LG smart diagnosis
LG Smart Diagnosis transmits a series of tones from the appliance to a smartphone app or call centre, allowing remote fault identification. The app is free to download and includes some genuinely useful extras. However, the diagnostic information it provides to customers is limited to basic faults – anything more complex still results in an engineer call-out recommendation. The technology is useful but the “revolutionise after-sales service” claim is overstated.
LG’s Smart Diagnosis system was launched on their 2011 washing machine and dishwasher range, with planned extension to refrigeration appliances. It allows a customer to hold a phone to a button on the appliance, press it, and transmit a series of audio tones that can be decoded by the LG app or a call centre to identify the fault. This article looks at what it actually delivers.
How LG Smart Diagnosis Works
The appliance transmits a sequence of tones through the Smart Diagnosis button. These can be picked up by:
- The LG Smart Diagnosis smartphone app, which decodes the tones and displays a diagnosis
- An LG call centre agent who listens to the tones over the phone and identifies the fault code
The app is available as a free download and includes additional features beyond the diagnostic function – a fabric care guide, stain removal guide, and links to LG appliance help videos.
What Does It Actually Diagnose?
The meaningful question is not how the tones are transmitted, but what diagnostic information is provided once the system has decoded them. Based on available evidence, Smart Diagnosis reliably identifies basic, user-resolvable faults – the same handful of common issues already described in the machine’s instruction manual:
- Water tap turned off or water supply restricted
- Door not properly closed
- Pump filter blocked
- Basic error codes with user-actionable remedies
For more complex faults – motor issues, PCB faults, heating element failures – the expected outcome is still a recommendation to book an engineer. The system does not provide more diagnostic depth than existing error code displays already offer; it simply provides a different mechanism for conveying the same information.
Existing appliances without Smart Diagnosis already generate error codes that can be read from the display and relayed verbally over the phone. Smart Diagnosis replaces that verbal relay with an audio tone transmission – a different method rather than fundamentally more diagnostic capability.
The Genuine Concern: Access for Independent Engineers
A pattern has been developing in the white goods industry of manufacturers restricting access to technical information – particularly error code meanings – in ways that favour their own service networks over independent engineers. See our guide on appliance error codes: friend or foe? for more on this.
The relevant question for Smart Diagnosis is whether the tone-based diagnostic system is accessible to independent engineers or only to LG’s own service agents. If the decoding capability is restricted to LG’s proprietary app and call centre, independent engineers cannot benefit from it when diagnosing an LG appliance.
Genuinely useful aspects
- Free app available to all customers
- Useful additional content – fabric guide, stain guide, help videos
- Reduces unnecessary engineer call-outs for simple, user-resolvable faults
- Allows remote support without the customer needing to read an error code
Limitations
- Diagnostic depth is limited to basic faults regardless of the technology used
- Complex faults still require an engineer – the technology does not change this
- If tone decoding is proprietary, independent engineers cannot use it
- “Revolutionise after-sales service” is a significant overstatement of what the system provides
The Broader Principle
After-sales service quality is one of the most important factors when choosing a white goods appliance – arguably more important than the list of features. A system that genuinely gives customers and independent engineers more diagnostic capability would be a meaningful improvement. A system that simply routes customers more efficiently toward the manufacturer’s own engineers, while presenting this as a customer benefit, is a different thing entirely.
The jury remains open on where Smart Diagnosis falls. If LG makes the full diagnostic capability accessible to independent engineers and customers alike, the technology has genuine value. If it functions primarily as a more sophisticated funnel to LG’s own service network, it is a commercial tool dressed as a consumer benefit.

Frequently Asked Questions
What is LG Smart Diagnosis?
LG Smart Diagnosis is a feature on some LG washing machines and dishwashers that transmits a series of audio tones from the appliance to a smartphone app or LG call centre. The tones encode diagnostic information about the appliance’s status, allowing remote identification of certain fault conditions without a physical engineer visit.
Can LG Smart Diagnosis fix my appliance without an engineer?
For simple, user-resolvable faults – a turned-off tap, a blocked pump filter, an improperly closed door – it may identify the cause and allow the owner to fix it themselves. For more complex electrical, mechanical, or electronic faults, the outcome will still be a recommendation to book an engineer. The technology does not change what faults can be fixed remotely; it changes how the diagnosis reaches the customer.
Can an independent engineer use LG Smart Diagnosis?
This depends on whether LG makes the tone decoding capability accessible to engineers outside their own service network. If the decoding is only available through LG’s proprietary app and call centre, independent engineers cannot benefit from it directly when working on an LG appliance out of guarantee.
Panasonic washing machines
Panasonic has an excellent reputation for consumer electronics, but white goods are a fundamentally different product category. The key questions for any washing machine brand are: how good is the after-sales service, are spare parts readily available, and do they have their own engineers or rely on third-party networks? On these measures, Panasonic’s track record in the UK white goods market is limited and the answers have historically been less reassuring than established white goods manufacturers.
Panasonic’s reputation in consumer electronics is well deserved. The question of whether that reputation translates to washing machines is less straightforward than it might initially appear.
Why Brown Goods Reputation Doesn’t Automatically Transfer to White Goods
Consumer electronics and white goods are manufactured in completely different ways, require different engineering disciplines, and present different reliability challenges. A television is a sealed unit with no moving parts in normal operation. A washing machine is a water-handling, heat-generating machine with multiple motors, pumps, bearings, seals, valves, and a drum rotating at up to 1600rpm under heavy load. Reliability is significantly harder to achieve and maintain in white goods than in consumer electronics.
Panasonic’s strengths
- Established reputation for quality in consumer electronics
- Strong commercial incentive to maintain quality standards across product categories
- Positioned in the mid-to-upper price range, suggesting quality focus rather than budget positioning
Reasons for caution
- Limited white goods track record in the UK compared to brands that have been producing washing machines since the 1950s
- Spare parts availability and technical information have historically been more difficult to obtain than from established white goods manufacturers
- No directly employed service engineers in the UK – relies on third-party repair networks
- White goods repair requires a very different infrastructure from brown goods servicing
Why After-Sales Service Matters More for White Goods
Consumer electronics rarely need repairs during their working life. Washing machines, by contrast, have significantly higher repair rates and require a well-established infrastructure of spare parts, technical documentation, and trained engineers to support them through their service life.
Spare parts availability
Washing machines need spare parts – pumps, bearings, door seals, carbon brushes, control boards. Established white goods brands have spare parts supply chains developed over decades. Newer entrants take time to build the same depth of parts availability, and the difference is felt by engineers trying to repair out-of-guarantee machines.
Technical documentation
Independent engineers need access to technical service documentation to diagnose and repair appliances. Some manufacturers make this readily available; others are reluctant to share it. Where technical documentation is difficult to obtain, machines become harder for independent engineers to repair effectively.
Engineer network quality
Panasonic, like most brown goods manufacturers that have moved into white goods, does not employ its own service engineers in the UK. It relies on third-party repair networks. The quality and consistency of third-party networks varies more than directly employed engineers. See our guide on manufacturer vs independent engineers.
How Panasonic Compares
Panasonic’s white goods are positioned in a similar price range to LG and AEG. At this price point, the relevant questions are: what does Panasonic offer that AEG or LG do not, and how does the after-sales proposition compare? Panasonic may perform well on reliability or features in specific areas, but the after-sales infrastructure is an important part of the overall value of a washing machine purchase – particularly when considering that most washing machines will need at least one repair during a typical service life.
For a thorough comparison of which brands offer the best combination of quality, reliability, and after-sales support at different price points, see our guide on which is the best washing machine to buy.
The Panasonic washing machine range was launched in the UK in 2009. The brand’s track record in UK white goods is consequently limited compared to manufacturers that have been producing washing machines here since the 1950s and 60s. A short track record is not a reason to avoid a brand, but it is a reason to look carefully at the after-sales provision before purchasing.

Frequently Asked Questions
Are Panasonic washing machines good quality?
Panasonic’s reputation in consumer electronics is strong and there is no reason to assume their washing machines are poorly built. However, washing machine quality is not simply a matter of initial build standard – the availability of spare parts, quality of the service network, and access to technical documentation all affect how well an appliance is supported over its service life. On these measures, Panasonic has less established provision in the UK than brands with decades of white goods history.
How does Panasonic compare to LG or AEG at the same price?
LG has been selling white goods in the UK significantly longer than Panasonic and has had more time to develop its parts and service infrastructure. AEG is part of the Electrolux group with a long white goods heritage. Panasonic at the same price point may offer comparable features and initial quality, but the after-sales comparison should be checked carefully before purchasing, particularly regarding parts availability and service engineer networks.
Does Panasonic have its own engineers in the UK?
No. Like most brown goods manufacturers that have moved into white goods, Panasonic relies on third-party repair networks rather than directly employed engineers. This is common across many brands but is worth factoring into the decision, as the quality and consistency of third-party networks varies more than directly employed service engineers.
Gorenje washing machines
Gorenje (pronounced “Gorenya”) is a well-established Slovenian appliance manufacturer selling in over 70 countries. In the UK they occupy the mid-to-upper market and are notable for offering a 5-year parts and labour guarantee on their washing machines, which is significantly better than the standard 1 or 2 year guarantees offered by most mainstream brands. They also have a reputation for working well with independent repair engineers – an important after-sales consideration.
Gorenje is a Slovenian appliance brand that has been less prominent in the UK market than some European competitors but is well established globally. Their washing machines are positioned in the mid-to-upper price tier with a stronger after-sales proposition than many mainstream brands.
What Makes Gorenje Notable in the UK?
5-year parts and labour guarantee
Gorenje offer a 5-year parts and labour guarantee on their washing machines – considerably better than the 1-year standard guarantee most mainstream brands provide. This is a meaningful commitment from the manufacturer and suggests confidence in their product’s durability. See our guide on what 5-year guarantees actually cover to understand exactly what is included.
Works with independent repairers
One of the most practical factors in assessing a washing machine brand is how well independent engineers can service them after the guarantee period. Gorenje’s approach of working closely with independent repairers and making spare parts and technical information accessible to the trade is a significant advantage over brands that restrict access to their own service networks. See our guide on manufacturer vs independent engineers.
Established global manufacturer
Despite being less well known in the UK than brands like Hotpoint, Bosch, or AEG, Gorenje has been producing appliances since 1950 and sells in over 70 countries. The brand is owned by Hisense, one of the world’s largest appliance manufacturers. This provides significant manufacturing and engineering resource behind the brand.
The j is pronounced as a y and the final e as an “a” sound – so “Gor-en-ya”. This is worth knowing if asking about parts or service by telephone.
Considerations Before Buying
The strengths – 5-year guarantee, independent repairer access, global manufacturing – make Gorenje a brand worth considering at the mid-to-upper price point. The questions to ask before purchasing any brand apply here too:
- Does the specific model have the features needed (drum size, spin speed, programme options)?
- Is the guarantee 5 years parts and labour, or parts only? Read the specific terms rather than assuming. See our guide on what 5-year guarantees actually include
- Are spare parts and repair support available locally if needed out of guarantee in future?

Miele washing machine user review
The Miele W3740 consistently draws praise from owners for its very low noise level, build quality, and straightforward operation. The one quirk worth knowing about before purchasing: the door cannot be opened without the machine being switched on, even after a cycle has completed. This is a minor operational point rather than a fault.
Miele W3740: What Owners Report
Exceptionally quiet operation
The Miele W3740 is consistently described by owners as very quiet – significantly quieter than budget or mid-range machines. Miele’s direct drive motor and heavy-gauge construction both contribute to reduced vibration and noise. At its quietest, the machine running in another room can be difficult to detect at all.
Sturdy, quality construction
Owners consistently note that every part of the machine – controls, door, drum, housing – feels solid and well-made compared to mainstream alternatives. The external finish is described as functional rather than design-led, which suits some buyers and not others.
Straightforward to use
The W3740’s control layout is clear and straightforward despite the range of programme options. New owners typically find the machine easy to use from the first wash without needing to consult the manual for basic operation.
Door only opens when switched on – one quirk to know about
The W3740 door cannot be opened without the machine being switched on at the main power button. After a cycle completes, the door remains locked until the machine is powered on to release it. This is by design rather than a fault, but it can catch new owners by surprise and differs from most mainstream machines where the door releases automatically after the cycle ends.
The Value Case for a Premium Machine
The most common objection to Miele washing machines is the purchase price. The counter-argument made consistently by owners who have switched from cheaper machines is one of total cost over time rather than upfront cost.
The budget machine calculation
A budget washer-dryer at around £350 that fails after four years costs approximately £87 per year. If replaced with a similar machine, the cycle repeats. Over 20 years, four or five machines are purchased, four or five machines are manufactured and disposed of, and the total expenditure significantly exceeds a single quality machine.
The Miele calculation
A Miele washing machine at approximately double the price of a budget machine, lasting five times as long, costs significantly less per year of use. A machine designed and built to last 20 years or more amortises its purchase cost over a much longer period than a machine expected to last four to seven years.
Manufacturing and disposing of multiple cheap appliances over the same period produces significantly more waste than a single quality machine. The energy and materials involved in manufacturing five budget machines over 20 years substantially exceeds that of one Miele. For households where environmental impact is a purchasing consideration, machine longevity is a relevant factor alongside running efficiency.

Frequently Asked Questions
Why won’t the door open on my Miele washing machine?
On the Miele W3740 and some other Miele models, the door release requires the machine to be switched on at the main power button. The door does not release automatically at the end of a cycle. Switch the machine on and the door should release. This is a design feature rather than a fault.
Is a Miele washing machine worth the extra cost?
Over the lifetime of the machine, yes for most households. A Miele is designed and built to last significantly longer than mainstream alternatives – often 15 to 20 years or more with normal domestic use. When the purchase cost is divided across a longer service life, the annual cost of ownership compares favourably to replacing a cheaper machine every four to seven years. The quieter operation, fewer repairs, and better build quality are additional factors most owners value.
Indesit Moon washing machine
The Indesit Moon was marketed with the tagline “Future Friendly” but proved to be neither. Independent testing found it performed poorly on the 40-degree wash most people use. Its novel soap dispenser behind the door prevented seeing inside the drum. And a design flaw preventing a 90-degree wash made it uniquely vulnerable to the black mould and grease build-up that eventually attracted a BBC Watchdog investigation.
The Indesit Moon was the subject of a BBC Watchdog investigation following widespread complaints about a severe black mould and grease build-up problem. The machine is uniquely unable to perform a 90-degree maintenance boil wash – the standard remedy manufacturers recommend for this type of build-up. If already owned, the mould problem can be managed but not fully resolved without a 90-degree cycle. The model is now discontinued.
The Marketing vs the Reality
The Indesit Moon was launched with a high-production TV advert using a soundtrack by New Order, futuristic visuals of robots integrated into human society, and the tagline “Future Friendly”. It was a memorable and well-made piece of advertising for one of the most budget-positioned brands in the UK washing machine market.
The “future friendly” tagline could reasonably imply an appliance built to last, or one so technically advanced it would not quickly become obsolete. Neither proved to be the case. For a product to be genuinely future-friendly, it must be reliable enough to justify repair when it fails, with spare parts priced at a level that makes repair economical. The Indesit Moon did not meet either criterion.
What Was Different About the Indesit Moon
What worked
- Extremely simple controls. A single control with just four wash programmes. For buyers who want simplicity over a confusing array of options, this was genuinely appealing
- Good rinsing performance. Independent testing found the Moon was notably good at rinsing – an unusual finding for a budget machine in a period when rinsing performance had become a widespread problem across the market
What did not work
- Poor wash performance at 40 degrees. Independent testing found the Moon performed poorly at the 40-degree wash most people use for the majority of their laundry – only adequate for light stains
- Soap dispenser behind the door removes the window. The novel dispenser placement replaced the standard door glass, eliminating the ability to see inside the drum during a wash. Visibility inside the drum is occasionally useful – for spotting something that should not be there
- Cannot do a 90-degree wash. The machine’s maximum wash temperature was below 90 degrees – which meant the standard maintenance boil wash that removes grease and mould could not be performed
- Severe black mould and grease problem. BBC Watchdog investigated the Moon following a high volume of complaints about grease, slime, and black mould build-up inside the machine. The absence of a 90-degree option made this particularly difficult to manage
The BBC Watchdog Investigation
The Watchdog programme featured the Indesit Moon due to the volume of complaints about grease, sludge, and black mould accumulating inside the machine. Black mould inside washing machines is a known issue across many brands – it is caused by washing predominantly at low temperatures, using liquid detergents, and not running regular maintenance washes. Most manufacturers recommend an occasional 60 or 90-degree cycle to clear the build-up.
The Indesit Moon had a specific design problem: it could not reach 90 degrees. This meant the primary remedy manufacturers recommend – and that Indesit itself recommends for other models – could not be applied to this machine. Owners were left managing the problem at 60 degrees, which is less effective.
For any owner of an Indesit Moon experiencing this problem, the guidance is:
-
Use powder detergent containing a bleaching agent rather than liquid detergent – liquid detergents contribute to build-up more than powders -
Run a 60-degree maintenance wash regularly with no laundry, using a machine cleaning product or soda crystals in the drum -
Leave the door ajar after each use to allow the drum to dry out -
Clean the door seal regularly, particularly in the fold, where mould accumulates

Frequently Asked Questions
Why is there black mould in my Indesit Moon washing machine?
The Indesit Moon is particularly susceptible to black mould and grease build-up because it cannot perform a 90-degree maintenance wash – the most effective way to clear this type of build-up. The problem was the subject of a BBC Watchdog investigation. Managing it on a Moon requires regular 60-degree maintenance washes using powder detergent with a bleaching agent, leaving the door ajar after use, and cleaning the door seal regularly. See our full guide on washing machine smells and black mould.
Can the Indesit Moon do a 90-degree wash?
No. This is the core design flaw that caused the widespread black mould complaints. The machine’s maximum wash temperature is below 90 degrees, which means the boil wash that manufacturers recommend for clearing internal build-up cannot be performed on this model. This limitation was not prominently disclosed at point of sale.
Is the Indesit Moon still available?
No. The Indesit Moon is a discontinued model. It is no longer in production or available new. Second-hand examples may occasionally appear but given the well-documented mould problem and the inability to perform a 90-degree maintenance wash, purchase of a used Moon is not recommended.
Miele direct enamel coating
Miele’s direct enamel coating is a fired enamel finish applied directly to the steel casing of their washing machines. Unlike paint applied over metal, enamel is extremely hard and chemically bonds with the steel surface. Miele guarantees the coating will never fade, chip, or corrode. In testing, the enamel resists hard coin strikes that would immediately strip the paint from standard appliance casings down to bare metal.
What Is Direct Enamel?
Most domestic appliances are finished with a powder-coated or wet-sprayed paint. This paint sits on top of the steel and, while durable under normal use, is vulnerable to chips and scratches from harder impacts. Once the paint layer is broken, the exposed steel beneath is susceptible to rust.
Miele’s direct enamel is a different type of finish. Enamel is a glass-based coating fired at high temperature directly onto the steel substrate. The process fuses the coating into the surface rather than simply layering it on top. The result is a coating that is significantly harder than paint and chemically bonded to the steel rather than sitting on its surface.
Miele direct enamel
- Fired into the steel surface at high temperature
- Extremely hard – resists hard coin strikes without scratching
- Guaranteed by Miele never to fade, chip, or corrode
- No exposed steel beneath even under heavy impact
- Finish remains intact throughout the machine’s designed 20-year service life
Standard painted appliance casing
- Paint applied over the steel surface
- Vulnerable to chipping and scratching from moderate impacts
- Scratches through the paint expose steel beneath
- Exposed steel areas can rust over time
- Finish may deteriorate before the end of the appliance’s service life
How Durable Is It in Practice?
Testing the enamel against a standard painted appliance casing reveals the difference clearly. A moderate strike with a coin against a standard painted appliance removes the paint immediately, exposing bare metal. Repeated hard strikes against Miele’s enamel casing produce no visible mark – not even a faint scratch.
This level of scratch resistance has practical implications for a domestic appliance. Washing machines regularly receive knocks from items being loaded, laundry baskets, furniture, and the normal traffic of a busy kitchen. The enamel finish will remain intact under normal domestic use in a way that painted casings typically will not over a machine’s full service life.
The direct enamel coating is one element of a broader build philosophy – components and finishes are specified to last the machine’s intended 20-year service life rather than to meet a minimum functional requirement. See our full guide on Miele washing machines for a broader overview of build quality and reliability.

Frequently Asked Questions
What is Miele direct enamel coating?
Miele’s direct enamel is a glass-based coating fired at high temperature directly onto the steel casing of their washing machines. Unlike paint, which sits on the surface of the steel, enamel is fused into it. The result is an extremely hard coating that Miele guarantees will never fade, chip, or corrode over the machine’s lifetime.
How does Miele enamel compare to standard appliance paint?
The difference is significant under impact. A moderate coin strike against a standard painted appliance casing removes the paint immediately, exposing bare steel that can subsequently rust. The same or harder strike against Miele enamel leaves no visible mark – not even a faint scratch. The enamel is substantially harder and more durable than painted finishes.
Does the enamel coating affect the rest of the washing machine?
The direct enamel is applied to the external casing. It does not affect the mechanical or electrical components of the machine. Its significance is that the casing finish matches the machine’s intended 20-year service life – unlike painted casings that may chip and rust long before the machine reaches the end of its operational life.
