Washing Machine Door Glass Exploding: How Real Is the Risk?
Reports of washing machine door glass suddenly shattering have been documented across many brands and price ranges for years. While the risk is statistically low, it is real – and the unpredictable nature of these failures makes it worth understanding the causes, the risks, and what to do if it happens to you.
Washing machine door glass can shatter due to impact damage from objects in the drum, thermal stress, overloading, or in rare cases manufacturing defects. Modern door glass is toughened (tempered) safety glass, which is designed to break into small pieces rather than large dangerous shards – but fragments can still cause cuts. The risk of serious injury is very low, but the failure can happen without warning, including when the machine is switched off.
What Actually Happens When Door Glass “Explodes”?
The word “exploding” is commonly used by consumers to describe what happens – and while alarming, it is not quite accurate. What occurs is a sudden structural failure of toughened glass, which shatters rapidly into multiple fragments rather than breaking cleanly.
Washing machine door glass is made from toughened (tempered) safety glass. This type of glass is manufactured under high internal tension, which causes it to shatter into smaller pieces when it breaks – rather than large, blade-like shards. This design is intended to reduce injury risk in the event of breakage.
Incidents have been reported both while the machine is running and while it is switched off and not in use. The latter is less common but is harder to predict and prepare for – and is one reason why the issue generates significant concern.
How Common Is This Problem?
There is no official industry dataset, so it is not possible to give a precise figure. What can be said is:
The number of incidents is very low relative to the millions of washing machines in use – but reports have been consistent over many years and across many brands.
Reports involve budget and premium brands alike. There is no strong evidence that any one manufacturer is significantly more or less affected than others.
Serious injuries directly caused by door glass failure are extremely rare. The most common harm is minor cuts when clearing up broken glass afterwards.
Glass can fail during a cycle or when the machine has been switched off for hours. This unpredictability is what makes the issue particularly concerning for households with children and pets.
What Causes Washing Machine Door Glass to Shatter?
1. Impact damage – the most common cause
The most widely accepted cause is prior impact damage to the glass – often unnoticed at the time. Coins, keys, or metal objects left in pockets can strike the door glass during the wash. Belt buckles, zips, and metal buttons on clothing repeatedly hitting the door also cause micro-scratches and stress points over time.
Toughened glass can absorb this kind of damage and remain intact for some time – sometimes weeks or months – before suddenly failing without any further trigger. This delayed failure is one reason why the cause is often difficult to identify and disputed.
2. Thermal stress
Washing machines heat and cool repeatedly during normal use. Over time, this thermal cycling can place cumulative stress on weakened glass. The release of this stress may explain why some doors shatter when the machine is not running – residual tension in the glass discharges unpredictably, sometimes hours after the last wash cycle.
This phenomenon is not unique to washing machines – it is also documented in oven doors and double-glazed window units, which use the same type of toughened glass.
3. Overloading and drum impact
Consistently overloading the drum increases the force with which laundry strikes the door during the wash and spin cycles. While machines are designed to handle normal use, repeated heavy loading may contribute to long-term weakening of the glass – particularly in combination with items that have hard fastenings.
4. Manufacturing defects
In rare cases, a flaw introduced during the manufacturing process – such as incorrect tempering or a stress concentration – can cause a door glass to fail earlier than expected, and sometimes without any obvious external trigger. This is difficult to prove and manufacturers rarely accept it as an explanation, but industry knowledge of toughened glass acknowledges that manufacturing faults can and do cause spontaneous failures.
Why Does Toughened Glass Sometimes Fail Without Warning?
This is the question that concerns most people – and understanding it requires knowing a little about how toughened glass is made.
Toughened glass is created by rapidly heating and then cooling standard glass. This process puts the outer surfaces into compression and the inner core into tension. The result is glass that is significantly stronger than ordinary glass – but which, when it does break, releases all of that stored energy simultaneously. This is why it shatters suddenly and completely rather than cracking progressively.
The implication is that damage – whether from an impact, a manufacturing flaw, or gradual stress – may remain invisible right up until the point of failure. The glass gives no visible warning. This behaviour is inherent to the material, not a specific defect in any one machine.
The same spontaneous failure behaviour has been observed in oven door glass, shower enclosures, and double-glazed window units – all of which use toughened glass. It is a property of the material, not a unique flaw of washing machine design.
How to Reduce the Risk
While the risk cannot be eliminated entirely, these practical steps significantly reduce the likelihood of door glass failure:
- ✅Always check pockets before loading – coins, keys, and small metal objects are a leading cause of glass damage
- ✅Zip up zips fully and turn garments with metal fastenings inside out before washing
- ✅Use mesh laundry bags for items with exposed metal buckles, decorative studs, or underwired bras
- ✅Do not overload the drum – excessive loading increases the force with which laundry strikes the door
- ✅Ensure the machine is level on stable flooring – excessive vibration increases stress on all components
- ✅Keep children and pets away from in front of the machine while it is running, as a precaution
What to Do If the Glass Shatters
-
Do not panic – while alarming, the risk of serious injury from the initial breakage is very low. Toughened glass is designed to break into smaller fragments rather than large dangerous shards.
-
Disconnect the appliance from the mains immediately. Do not attempt to use it or open it further until the power is off.
-
Wear protective gloves before touching anything. Even toughened glass fragments can cause cuts. Clear the glass carefully and thoroughly – check inside the drum, under and around the machine.
-
Photograph everything – the broken glass, the machine, the drum contents, and the surrounding area. This evidence is important if you need to make a complaint or claim.
-
Contact the manufacturer and the retailer. Report the incident to both. Read our guide on who is responsible for exploding door glass before speaking to them – manufacturers commonly attribute blame to the user, and knowing your position in advance is valuable.
-
Do not use the machine until the door assembly has been professionally inspected and replaced. Contact a qualified repair engineer to assess and repair the appliance.
Who Is Responsible – You or the Manufacturer?
This is one of the most contentious aspects of door glass failures. When consumers report incidents, manufacturers almost universally respond by attributing blame to the user – claiming overloading, metal objects in the drum, or incorrect use. In most cases, they cannot prove this – but equally, consumers typically cannot prove it was a manufacturing defect.
The glass was damaged by a foreign object, overloading, or incorrect use. They rarely accept that toughened glass can fail spontaneously – even though this is a documented property of the material.
If you washed normal laundry in line with the machine’s instructions, left no obvious foreign objects in the drum, and the machine was used correctly, it is reasonable to argue the failure was not your fault. Under the Consumer Rights Act, appliances must be of satisfactory quality and durable.

Frequently Asked Questions
Is it safe to stand in front of the washing machine while it is running?
For most people in most circumstances, yes – door glass failures are statistically very rare. However, as a precaution, it is sensible to discourage young children and pets from standing directly in front of a running machine. The risk of serious injury from a failure is extremely low, but the unpredictable nature of the event means basic precautions are reasonable.
My door glass shattered while the machine was switched off – how is that possible?
This is one of the most alarming aspects of this issue – and it is a documented behaviour of toughened glass. Residual stress built up through thermal cycling or prior impact damage can be released unpredictably, even hours after the last wash cycle. The glass gives no visible warning before failure. This behaviour is inherent to toughened glass and is not unique to washing machines.
The manufacturer is blaming me – what should I do?
This is a very common response. Manufacturers routinely attribute door glass failures to user error – overloading, foreign objects, or incorrect use – because it is almost impossible to prove a manufacturing defect after the fact. If you used the machine correctly and followed the instructions, you have grounds to push back. Read our detailed guide on who is responsible for exploding door glass, and our consumer rights guide for further support.
Are some brands more prone to this than others?
Reports involve a wide range of brands across all price points – including budget and premium manufacturers. Without verified industry-wide data, it is not possible to reliably rank brands by risk. Our broken door glass photos and brand tally page records reported incidents by brand, which may provide some useful context.
Can I claim for the cost of repair or a replacement machine?
Possibly – particularly if the machine is relatively new or still under warranty. Under the Consumer Rights Act 2015, appliances must be of satisfactory quality and last a reasonable amount of time. If the machine is within six months of purchase, the fault is presumed to be inherent unless the retailer can prove otherwise. After six months, the burden of proof shifts to you. See our Consumer Rights Act guide for full details.
Is the glass inside the drum safe after a failure?
Not immediately. After a door glass failure, fragments will be present inside the drum, on the door seal, and on the floor around the machine. Do not attempt to use the machine, and do not reach inside without wearing protective gloves. The drum contents will likely be unusable. The machine will need a full door assembly replacement by a qualified engineer before it can be safely used again – book a repair engineer to assess it.
Our dedicated page features reader-submitted photos of shattered door glass across many brands, along with a running tally of reported incidents by manufacturer.
Disconnect power immediately. Wear gloves before touching anything. Photograph everything before clearing up. Do not use the machine until professionally repaired.
I’ve just had a Miele engineer out to my 4 and half year old Miele washing machine WWE320 power wash because the glass door shattered mid spin cycle.
It’s shredded the clothes inside and the rubber seal and we’re lucky it didn’t pierce the plastic outer door casing and kill us!
Miele do not accept responsibility that there maybe a manufacturing fault and have condemned the machine as beyond repair.
They have attempted to charge us their mandatory £175 call out fee and have offered to put me in touch with their sales team to do a “deal” on a new washing machine.
Flabbergasted!!!
Hello Rachel. Yes, that is very poor indeed. And £175 just to tell you that your washing machine is not worth repairing is outrageously expensive. It just goes to show that sadly, Miele appliances, whilst still the best available, are not the solid investment that they always used to be any more.
I have 3 or 4 articles on this particular subject, so make sure you have read them all (they should all be linked to in this article). That way, you can fully understand the issue. Pay particular attention to the, “who’s fault is it?” article. Unfortunately, that article points out how it is impossible to prove that it has been caused by a manufacturing fault. However, at the same time, it is also usually impossible to prove that it has been caused by the customer.
Manufacturers should be well aware of this, and offer to at the very least meet customers half way. Unless they can show that the washing machine has not been used in accordance to instructions, and that has led to the broken glass, then they cannot say that it is caused by a customer.
Anyone who knows anything about high tension safety glass knows that it is potentially volatile, and can shatter spontaneously, often with no clue as to why. Although such incidents are commonly caused by damage to the glass, often micro scratches, I can say is an experienced engineer, that a washing machine door glass is always receiving micro scratches during its normal use.
Any item with metal buttons, zips etc. will typically be hitting the door glass during the wash cycle. So it is perfectly reasonable to assume that small scratches are a normal result of washing laundry. Read the instruction manual carefully. Does it say anything about not washing any items with certain types of buttons or zips? If it says something like you should zip or button them up, and/or wash them inside out, or inside net bags etc. then they have arguably covered this.
If there is no mention at all, and the implication is that you are perfectly entitled to wash all of your normal laundry (some of which may have zips or even metal buttons), then unless you have left coins inside pockets, or washed something with obviously unsuitable buckles etc. then you should be able to argue you have done nothing wrong. (But you can’t prove it, and can they prove otherwise?)
I would ask the manufacturers to demonstrate, or point you to evidence as to how it is NOT possible for this type of high tensioned safety glass to shatter due to manufacturing flaws, or due to normal wear and tear caused by zips etc. hitting it during a normal wash cycle.
As I said before, ultimately, it is extremely difficult for either party to prove that it is the other party to blame. Manufacturers just wash their hands of it because the last thing they want to do is accept responsibility, or accept that yes they can just suddenly shatter for reasons very few people understand. It is extremely easy for them to just blame the customer, and it seems to be what they all do, and they know that most customers will not or cannot fight that.
Have a Whirlpool model WFW86HEBW1 which blew out the glass into large shards, small pieces and tiny slivers right at the beginning of a wash cycle, while I was watching through the door at the time. Had just loaded a mattress pad I have washed in it many, many times before. No metal of any kind within.
The glass door on my Beko 1200 exploded this morning part way through a 90 degree wash.
It was terrifying and I was shocked and shaken. There were shards of sharp glass on the kitchen floor and in the clothes in the machine.
I then spent most of the day on the phone to Beko. First they wanted full details of the machine and purchase info. Then they said there was nothing they could do as it was out of warranty. I appreciate the machine is 17 months old but this is a safety issue not a warranty one.
I tried again and was told to send them all the info in an email to customer services.
I don’t know where to go next as I think I will be ignored.
Any advice would be gratefully received. Having a washing machine is like having an unexploded bomb in your house
Brand new Haier I-Pro Series 3 HW80-B14939 8Kg 1409 spin washing machine. Bought 7th Nov, delivered & installed (by the company) on 15th Nov. Single wash run at low temperature. No metal on clothes / in pockets. While I was out at work yesterday the glass shattered. Nobody was in the house. Nothing has hit the door. My previous machine (also Haier) stood in the same place for 13years and the glass was not the thing that failed.
Our Miele w1 washer door shattered, glass was contained in unit and outer glass of door didn’t break. Appears to have continued spin cycle , shredding clothes. There was only sportswear and a night gown in the unit. Have called miele but so far no response from their repair service. What should our expectations be? Do we need a replacement machine because of all the glass shards or is it repairable? We bought unit in 2021 and bought the three year warranty.
Hello Jay. Unfortunately it’s not possible to predict what a manufacturer will say or do. As my article suggests, most manufacturers tend to blame the user. So if they say it is caused by the user, they are unlikely to be very helpful. However, if they say it is caused by overloading, I would ask them why their washing machines are not designed to cope with the simple case of overloading, which virtually everybody does at one time. If they say it is caused by some metal object, such as a belt buckle or even a coin, I would also ask them why their washing machine, a premium brand, is not strong enough to cope with that?
At the end of the day, it is not a strong position to be in because we can’t really prove that it is a design fault, even if that is strongly suspected. Some manufacturers have apparently done free repairs or replacement machines. The best advice I can give is to carefully read this article, and all the comments, which all give people’s personal experience of this issue. Then read this article Broken door glass – who’s fault is it?. That way you will at least have a very good understanding of the issue
Bosch door exploded – absolutely gutted happy to send pics – luckily had a plastic outer piece so safety covered in part but devastated about clothes which will be ruined – have booked engineer visit as under warranty but not sure they can ‘fix’ as machine us full of glass now – shocking
My Bosch washing machine exploded yesterday while I was cooking in the kitchen . It was not operating at the time. I had sometime before put a small dark load with the intention of more items later in the day . I can only describe it like an explosion followed by the sound of shattering glass. I didn’t know initially where it had come from. My machine was purchased 28th March 2022 so is less than a year old .It shattered into many sharp dangerous pieces. I took photos and then took along time clearing up the mess and shards of glass. I got it from John Lewis . They said contact Bosch . The Bosch representative I spoke to clearly did not believe me and said I must have overloaded the machine even though I had explained that the machine was not on when it happened. They are sending an engineer to determine the cause and say I will have to claim on my house insurance if it is classed as accidental damage . I am furious that they are suggesting it is my fault.
Hi Dawn. It’s frustrating because all the manufacturers say exactly the same thing. First they say they’ve never heard of the problem, and secondly they say you must have overloaded it, or you must have left something metal inside the washing machine. To be fair, my impression is that it is quite a rare incident these days. It seemed to happen a lot several years ago when I first wrote these articles, but then petered out. Maybe manufacturers improved something?
But what I can say is that I have been repairing washing machines since 1976, and this never used to happen.
I’ve seen many washing machines so badly overloaded, and so badly out of balance (this is before they invented out of balance control) that washing machines literally jumped up into the air, and walked across the kitchen. Sometimes as far as the attached hoses would allow them. I’ve seen them bash great big dints in both sides of the washing machine’s casing and damage cupboards.
I’ve also seen great big scars on the door glass where the revolving drum lip had caught relentlessly on it during spin, and cut big marks into the door glass. I’ve also seen countless washing machines with pen knives, large coins, large buckles etc. stuck inside the washing machine. These objects caused extensive damage to the inner drum and the outer tub, but never damaged the door glass.
Washing machines door glass used to be extremely thick, and strong. I can only speculate that at some point in relatively recent history, manufacturers changed the type of glass that they use to what is called safety glass. Safety glass is created under high tension, and designed to shatter into many small pieces if it breaks. The idea is that in a breakage, glass will shatter into small “safe” pieces.
However, my experience shows that safety glass was completely unnecessary. I only ever had to replace a couple of washing machine door glasses in 30 years. As far as I recall they were all due to unusual incidences such as someone dropping something heavy onto the open door of a washing machine, causing it to crack (not break).
So why would they start to make them out of safety glass all of a sudden? Possibly there could have been some legislation that forced it. Or maybe they reduced the thickness of the door glass in order to cut costs, and realised that they had better now make it out of safety glass because it is now vulnerable to being broken?
This is obviously just speculation. I do not know the answer. An important thing to understand is that safety glass seems to have an ability to spontaneously explode. It’s happened for many years on the glass on oven doors. It can even happen on double-glazed window units. It happened to me. We had a double-glazed unit in our conservatory roof which just spontaneously exploded one (very) hot day after 9 years.
A major problem seems to be that it’s extremely difficult or even impossible to ascertain exactly what caused any glass to spontaneously explode. Manufacturers who use this type of glass just seem to accept that this is what it does, it’s one of those things, it’s rare but it just happens. However, this is not really good enough when we the consumers suffer financial loss because of it. No one says when you buy these products that the glass can sometimes spontaneously explode for no apparent reason and that this is normal, and just one of those things.
When I have researched it, though, I have seen references to manufacturing faults. It’s possible that during manufacture, some flaw or error is introduced, which results in door glass failure sometime in the future. It’s also possible that some force from a metal object could damage the door glass and either cause it to break instantly, or introduce a weakness that causes the explosion some time later. Possibly due to change in temperature.
My experience is that any company faced with having to replace any of this glass that has exploded always acts the same. They say it’s nothing to do with them, and you have to pay for it. We would probably need some glass experts to advise on this issue.
In my case, when my conservatory roof spontaneously exploded, I argued with the company that fitted it, that many sources on the Internet that say a manufacturing fault can cause it. Or that it can happen if it is fitted poorly, and under some sort of pressure. The company replaced my conservatory roof double-glazed panel, and did not charge me.
Thank you so much for writing this reply . Thank you for taking the time and also your expertise in this matter. The engineer is coming today to determine the cause and it really helps to have some background knowledge on this especially if there is disagreement.
Kind regards
Dawn Parkinson.
Tally on the Electrolux washer glass explosion. Happened as it was not on/running a load as the last load was done 8 hours earlier.
Thanks Melissa. I’ve added yours to my list here – https://www.whitegoodshelp.co.uk/broken-door-glass-photos/
The glass in the door of our front load washer suddenly shattered. Thankfully, no one was in the room when it happened. It was not running at the time.
Electrolux
Model EFLS517SIW0
Produced in No 2017
We purchased in Dec 2017
Incident occurred in Jun 2023
Electrolux response
“ Was anyone hurt? Any property damaged?”
When I said no, response was “we will give you a 20% discount on a new glass.”
I appreciated the discount but I really want to know if anyone is tracking incidents and if Electrolux is determining why the glass is shattering.
Since I do not put belts or other items that could bang against door in the washer, that could not be the cause.
My beko washing machine door exploded on me last week it totally shattered into big and small pieces I just literally left the kitchen when I happened luckily my little boy was sat in the living room and no one was hurt. I’ve never been so shocked in my life with the loud bang that it created. I have photos on my phone as my friends and family didn’t believe me.
Hello Angela. Consequential loss is when you are forced by law to compensate someone who suffered a consequential loss due to something that was your fault. If a customer is claiming consequential loss then that’s a matter for the small claims courts and the consumer law. No one decides whether to comply to that are not. They are either liable under consumer law, or not. It’s a bit disappointing when companies do this, especially a company like Miele who strive for the highest standards. The amount of money that it is likely to cost them to compensate you is peanuts to them. I don’t understand why they would rather lose a customer and gain extra bad publicity.
