Haier Washing Machine Error Codes
Haier washing machines display error codes as Err followed by a number — Err1, Err2, Err3 and so on, up to E10 or E13 on some models. The most commonly seen Haier codes are Err1 (door lock fault), Err2 (drain fault), and Err5 (fill fault). All current Haier washing machines use brushless Direct Motion motors with no carbon brushes, so motor fault codes do not relate to brush wear. Find your code in the table below.
Which Haier washing machines does this guide cover?
This guide covers all Haier washing machines and washer dryers sold in the UK, including the HW100, HW90, HW80, HW70 series (where the number indicates capacity in kilograms), the HWD washer dryer series, and the I-Pro Series 7 and I-Pro Series 7 Plus premium ranges. Haier is the world’s largest white goods manufacturer by volume and is also the parent company of Hoover and Candy through its Haier Europe division.
Haier washing machines display fault codes with the prefix Err — Err1, Err2, Err3 and so on. Some Haier models display higher numbered codes (E10, E13) without the Err prefix, but these follow the same general code system. Write the exact code down before doing anything else.
All current UK Haier washing machines feature the Direct Motion motor — a brushless direct drive inverter motor with no carbon brushes. This is important when diagnosing motor codes (Err6, Err7): brush wear is not a possible cause on Haier machines, unlike older Bosch, Hotpoint, or Indesit machines. Motor fault codes typically point to the motor itself, the speed sensor, or the inverter board.
Haier owns Hoover and Candy through Haier Europe, acquired in 2019. While Hoover and Candy continue to use the E code system inherited from their pre-acquisition platform, Haier-branded machines use the Err code system. The brands are owned by the same group but the error code naming differs between Haier and the Hoover/Candy product lines.
To clear a Haier error code, press and hold the START/PAUSE button for approximately 3 to 5 seconds. For a deeper reset, switch off at the wall socket, wait 60 seconds, and switch back on. Clearing the code does not fix the underlying fault — if the same code reappears, the fault is real and needs diagnosis.
Haier washing machine error codes: complete reference
| Code | Fault description | Most likely causes | Check first |
|---|---|---|---|
| Err1 | Door lock fault — machine not detecting the door is closed and locked | Door not fully closed. Failed door interlock mechanism. Faulty door wiring. Failed door latch. Power supply issue affecting the lock circuit. | Open and firmly close the door, ensuring nothing is trapped in the door seal. Many Err1 faults are resolved by simply closing the door more firmly. If the door closes correctly and Err1 persists, test the door interlock for continuity. Door interlock replacement is a common Haier repair — genuine parts are available through our spare parts section. |
| Err2 | Drain fault — water has failed to drain from the machine within the expected time | Blocked pump filter (the most common cause). Kinked or blocked drain hose. Standpipe too high. Foreign object blocking the pump impeller. Failed drain pump motor. Wiring fault to drain pump. | Clean the pump filter — behind the small access panel at the bottom front of the machine. Place towels and a shallow tray in front before opening as water will flow out. Unscrew anticlockwise, remove all debris, check the pump cavity for foreign objects, and refit firmly. See our full guide: washing machine not draining. |
| Err3 | Wash temperature sensor error — NTC thermistor fault | Failed NTC thermistor. Loose or corroded wiring connector to the thermistor. Limescale on the thermistor in hard water areas. Control board fault. | Test the NTC thermistor with a multimeter. In hard water areas, run a descaling cycle on a hot programme before testing or replacing components, as limescale on the sensor can produce this code without the thermistor actually failing. |
| Err4 | Overflow condition detected — too much water in the drum | Excessive foam from too much detergent (most common cause). Wrong type of detergent (standard detergent in an HE machine). Inlet valve stuck open allowing continuous fill. Pressure sensor fault. Pressure switch hose blocked. | Check through the door glass for visible foam. If foam is present, run an empty rinse-and-spin cycle to clear it. Reduce detergent quantity on future washes and use only HE-compatible detergent. If no foam is visible and water is genuinely overfilling, the inlet valve has likely failed. |
| Err5 | Fill fault — machine cannot detect that it has filled with enough water within the expected time | Tap closed or partially closed. Kinked or trapped inlet hose. Blocked inlet hose filter. Low mains water pressure. Failed inlet valve solenoid. In cold weather, frozen inlet hose. Pressure switch fault. | Confirm the tap is fully open. Straighten the inlet hose. Unscrew the inlet hose from the back of the machine and clean the small mesh filter inside the inlet port. Check household water pressure is adequate. |
| Err6 | Heating fault — water not reaching target temperature | Failed heating element. Failed NTC thermistor. Wiring fault between element or thermistor and control board. Limescale heavily fouling the element in hard water areas. Overloading reducing heating efficiency. | Reduce the load if Err6 appeared on a heavily loaded cycle. Test the heating element for continuity with a multimeter — open circuit confirms failure. Test the NTC thermistor. In hard water areas, run a descaling cycle before testing components. |
| Err7 | Motor error — drive motor overheating or motor circuit fault | Main drive motor has overheated and the thermal cut-out (TOC) has tripped. Motor connection block fault. Wiring fault to motor. Failed motor windings. Inverter board fault. Important: Haier uses brushless Direct Motion motors — there are no carbon brushes to check or replace. | Allow the machine to cool fully before restarting (typically 30 minutes to an hour). If Err7 was triggered by overheating from a heavy load, reducing the load on the next cycle should prevent recurrence. If Err7 persists with normal loads, engineer diagnosis is required for motor and inverter board testing. |
| Err8 | Water level exceeds protective limit / service required | Failed pressure switch reading water level incorrectly. Inlet valve stuck open causing severe overfill. Failed control board. Drain system fault preventing water level from reducing. | Engineer diagnosis recommended. Confirm visually whether the drum is genuinely overfilled or whether the pressure switch is reading incorrectly. Check pressure switch hose for blockage. |
| Err9 | Service required — internal fault detected | Various — varies by model and software version. Often relates to communication faults between modules or pressure sensor issues. | Switch off at the mains for 60 seconds and restart. If Err9 clears, the cause was transient. If it persists, engineer diagnosis is required to identify the specific underlying fault. |
| E10 | Service required — control board / communication fault | Internal communication fault between the main control board and the inverter board. Wiring harness fault. Module failure. | Power cycle the machine. If E10 returns consistently, engineer diagnosis is required for the control or inverter board. |
| E13 | Drying fault on washer dryer models / lint buildup | Lint filter blocked on washer dryer models. Drying air outlet blocked. Drying heater fault. Drying fan fault. | Applies primarily to washer dryer models. Clean the lint filter thoroughly. Check drying air vents are not blocked. Engineer diagnosis required for drying heater or fan faults. |
The most common Haier washing machine faults
Blocked pump filter (Err2)
Drain faults are the most common cause of error codes on Haier washing machines, and the underlying cause is almost always a blocked pump filter rather than a failed pump. Coins, buttons, hair grips, and bra underwires accumulate in the filter over time. Cleaning takes five minutes and resolves most drain faults without any parts. Treat it as routine maintenance every few months regardless of whether a code has appeared.
Door interlock failure (Err1)
The door interlock is a common wear point on Haier washing machines, as on most brands. It locks the door during the cycle and releases it when safe — mechanical stress over thousands of cycles eventually leads to failure, typically between five and ten years of regular use. Replacement interlocks for most Haier models are widely available, and the repair is practical for a confident DIY user.
Excess foam triggering Err4
Err4 overflow on Haier machines is most often caused by too much detergent rather than an actual mechanical overflow. Modern washing machines use far less water than older machines, which means the same dose of detergent produces much more foam. The pressure sensor reads the foam as additional water and triggers an overflow code. Reducing detergent and using HE-compatible products usually resolves recurring Err4 faults without any component replacement.
Direct Motion motor faults (Err7)
Because Haier uses brushless Direct Motion motors, motor fault codes (Err7) typically point to the motor itself, the speed sensor, the inverter board, or the wiring between the motor and the control board. There are no carbon brushes to check or replace on Haier machines — looking for them is a common mistake when diagnosing motor codes. The advantage of brushless direct drive motors is significantly longer service life than traditional carbon brush motors before any intervention is needed.
What to check before calling an engineer
-
Power cycle the machine. Switch off at the wall socket, wait 60 seconds, and switch back on. Many transient codes — particularly communication errors and some board codes — clear on a power reset. If the same code returns consistently, it represents a real fault.
-
Clean the pump filter (Err2 drain code). The filter is behind the small access panel at the bottom front of the machine. Place towels and a tray in front before opening. Unscrew anticlockwise, remove all debris, check the pump cavity, and refit firmly. This single check resolves the majority of Err2 faults.
-
Check the door closes correctly (Err1 door code). Open and firmly close the door, ensuring nothing is caught in the seal. If the code persists, test the door interlock for continuity.
-
Check the water supply (Err5 fill code). Confirm the tap is fully open, the inlet hose is not kinked, and the inlet filter mesh inside the inlet port is clean.
-
Reduce detergent and clear foam (Err4 overflow code). If foam is visible through the door glass, run an empty rinse-and-spin cycle to clear it. Reduce detergent on future washes and use only HE-compatible detergent.
-
Allow the machine to cool (Err7 motor code). If the motor has tripped its thermal cut-out, the machine will not restart until the motor has cooled. Wait 30 minutes to an hour and try again with a smaller load on the next cycle.
-
Descale the machine (Err3, Err6 heating codes in hard water areas). Run an empty cycle on the hottest programme with a proprietary descaler before testing or replacing the heating element or thermistor. Limescale can produce false readings without any component actually failing.
-
Clean the lint filter (E13 on washer dryer models). Wash dryer models have a separate lint filter that requires regular cleaning. A blocked lint filter prevents proper drying and triggers fault codes.
Always switch the machine off at the wall socket and unplug it before accessing the pump filter, opening any panels, or inspecting internal components. Never work on electrical components with the machine connected to the mains. See our DIY appliance repair safety guide.
Can I fix a Haier error code myself?
Straightforward to check or fix yourself
Cleaning the pump filter (Err2 drain code). Checking and cleaning the inlet hose filter (Err5 fill code). Checking the door closes correctly and testing the interlock (Err1). Replacing the door interlock on confirmed failure. Reducing detergent and clearing foam (Err4). Power cycling to clear transient codes. Descaling for heating codes in hard water areas (Err3, Err6). Allowing motor to cool (Err7 motor overheat). Cleaning the lint filter on washer dryer models (E13). Replacing the heating element or NTC thermistor on confirmed failure. Replacing the drain pump on confirmed failure.
Requires an engineer or advanced competence
Direct Motion motor faults — there are no brushes to check, so any motor diagnosis requires engineer testing (Err7 if cooling and load reduction do not resolve). Inverter board faults. Pressure switch replacement (Err4, Err8) if hose checks are clear. Communication faults that persist after power cycling (Err9, E10). Drying heater or fan faults on washer dryer models (E13). Any control board fault. Any fault that persists after all basic checks have been completed.
Haier and the wider group: Hoover and Candy
Haier acquired the Hoover and Candy brands through its purchase of the Candy Group in 2019, forming Haier Europe. As a result, Haier is the parent company of three washing machine brands sold in the UK: Haier, Hoover, and Candy. Each brand uses its own error code system on legacy product lines — Haier-branded machines use the Err code system covered in this guide, while Hoover and Candy machines continue to use the E code system from their pre-acquisition platform.
The brands also occupy different positions in the market. Haier-branded machines are typically positioned at the mid to premium end with features such as Direct Motion motors, Wi-Fi connectivity via the hOn app, and 5-year warranties. Candy machines target the budget end of the market, while Hoover sits between the two. Despite the shared ownership, the underlying machine designs and platforms continue to differ between the brands.
If you have a Hoover or Candy machine rather than a Haier-branded one, see our Hoover washing machine error codes guide or Candy washing machine error codes guide respectively.
Haier error code pointing to a fault you cannot resolve?
If basic checks have not cleared the fault, a qualified engineer is the right next step. We cover Haier washing machine repairs nationwide with genuine spare parts available for most models including door interlocks, drain pumps, heating elements, NTC thermistors, and Direct Motion motor components.
Frequently asked questions about Haier washing machine error codes
What does Err2 mean on a Haier washing machine?
Err2 is a drain fault — the machine has been unable to drain water within the expected time. In the vast majority of cases the cause is a blocked pump filter rather than a failed pump. The filter is behind the small access panel at the bottom front of the machine. Cleaning it takes around five minutes and resolves most Err2 faults without any parts or engineer visit. If the filter is clear and Err2 persists, check the drain hose for kinks then test the drain pump motor.
What does Err1 mean on a Haier washing machine?
Err1 indicates a door lock fault — the machine is not detecting the door is properly closed and locked. First confirm the door closes fully with nothing obstructing the seal. Many Err1 faults are resolved by simply closing the door more firmly. If it closes correctly and Err1 persists, the door interlock has likely failed and requires replacement. Door interlock replacement is one of the most common Haier washing machine repairs.
What does Err7 mean on a Haier washing machine?
Err7 indicates a motor error — typically the main drive motor has overheated and the thermal cut-out has tripped, or a fault has been detected in the motor circuit. Allow the machine to cool fully before restarting (30 minutes to an hour). If Err7 was triggered by overheating from a heavy load, reducing the load on the next cycle should prevent recurrence. Important: Haier uses brushless Direct Motion motors with no carbon brushes — there are no brushes to check or replace, so any persistent motor fault requires engineer diagnosis for the motor, speed sensor, or inverter board.
Do Haier washing machines have carbon brushes?
No. All current UK Haier washing machines feature the Direct Motion motor — a brushless direct drive inverter motor with no carbon brushes. This is important when diagnosing motor codes (Err6, Err7): brush wear is not a possible cause on Haier machines, unlike older Bosch, Hotpoint, Indesit, or Zanussi machines that use traditional carbon brush motors. Direct drive motors typically last significantly longer than brushed motors before requiring any intervention.
How do I clear an error code on a Haier washing machine?
Press and hold the START/PAUSE button for approximately 3 to 5 seconds to clear the displayed code. For a deeper reset, switch the machine off at the wall socket, wait 60 seconds, and switch back on. Important: clearing the code does not fix the underlying fault. If the same code reappears as soon as you restart the cycle, the fault is genuine and needs to be diagnosed and repaired.
Are Haier, Hoover, and Candy the same company?
Yes. Haier acquired the Candy Group, including the Hoover and Candy brands, in 2019, forming Haier Europe. The three brands are now owned by the same group but occupy different market positions and use different error code systems. Haier-branded machines use the Err code system covered in this guide, while Hoover and Candy machines continue to use the E code system from their pre-acquisition platform. Despite shared ownership, the underlying machine designs and platforms continue to differ between the three brands.
Are Haier washing machine spare parts available in the UK?
Yes. Haier has expanded significantly in the UK market over the past decade and spare parts are widely available through Haier’s UK service network, through general appliance parts suppliers, and through independent appliance engineers. Common parts including door interlocks, drain pumps, heating elements, NTC thermistors, and pressure switches are widely available. Specialist parts such as Direct Motion motor components and inverter control boards are typically sourced through the official Haier service channel.
