Miele is a renowned German electronics manufacturer, widely recognized for producing high-quality appliances, including their popular washing machines. Miele washing machines are known for their exceptional performance, long service life, low noise levels, and impressive A+++ energy ratings, which ensure that your laundry receives the best possible care.
However, even with the superior quality of Miele washing machines, occasional issues may arise. Fortunately, Miele has incorporated a helpful feature into their machines – error codes. These error codes provide valuable information that can assist in diagnosing and resolving problems, even if you are not able to fix the issue yourself.
Here is a list of some common Miele washing machine fault codes:
Miele washing machine fault codes
Error codes can help diagnose an issue with your Miele washing machine. The specific number identifies what the error is in the system, and can be helpful in finding a resolution to the problem, even if you can’t fix it yourself.
A Miele washing machine fault codes list includes:
Code F1/F2
Indicates a short-circuit in the NTC sensor, typically caused by water or heating-related problems.
What it means: The temperature sensor is reporting impossible readings, often due to water ingress or a failing heating element.
DIY check: Switch off at the wall, wait five minutes, then switch back on. If the code returns, switch off again, remove the rear panel (if you’re confident) and look for corrosion around the sensor wiring.
Next step: If still locked on, book a sensor or element replacement.
Code F10
Indicates a water intake issue.
What it means: Your machine isn’t getting sufficient water. Could be a closed stopcock, blocked inlet filter or faulty inlet valve.
DIY check: Turn off the water, unscrew the inlet hose, clean the mesh filter and reconnect. Make sure the stopcock is fully open.
Next step: If that doesn’t clear it, arrange an inlet-valve inspection.
Code F11
Points to difficulties in water drainage.
What it means: Water cannot exit the drum fast enough. Usually a blocked filter, kinked hose or faulty drain pump.
DIY check: Remove the lower kick-strip, clear out the debris filter, then straighten the drain hose behind the machine.
Next step: Persistent F11? Book a drain-pump service.
Code F15
Indicates a fault in hot water intake.
What it means: The machine isn’t detecting the correct temperature on the hot-water feed.
DIY check: Verify that the hot-water supply valve is open and that the hose isn’t kinked.
Next step: If still locked, get a hot-water inlet-valve replacement.
Code F16
Signals the detection of excess detergent.
What it means: Too much or the wrong type of detergent has caused foam overload.
DIY check: Run a rinse cycle without detergent. Wipe any residue from the drawer and switch to the recommended low-foam detergent.
Next step: If code returns, have the foam sensor checked.
Code F19
Indicates a slow flow meter, leading to rotation complications.
What it means: The device that measures incoming water flow is blocked or failing.
DIY check: Clean the small filter screen on the flow-meter (inside the inlet valve).
Next step: If that fails, book a flow-meter replacement.
Code F20
Points to heating malfunctions.
What it means: The heater element is not reaching target temperature.
DIY check: Switch off, unplug and test for continuity with a multimeter (only if qualified).
Next step: Otherwise, arrange for a heating-element inspection.
Code F29

What it means: The control board isn’t loaded with the correct programme map for your model.
DIY check: None.
Next step: You’ll need a firmware re-flash from a trained technician.
Code F45
Suggests defective Flash Ram, resulting in incorrect data supply.
What it means: Non-volatile memory is failing to store settings.
DIY check: None.
Next step: Arrange for a Flash-RAM replacement.
Code F50
Indicates a drive issue.
What it means: The motor drive is reporting overload or failure.
DIY check: Reduce load size and retest.
Next step: If unchanged, have the drive inverter and motor inspected.
Code F51
Points to a level switch or sensor pressure problem.
What it means: The machine can’t detect correct water level.
DIY check: Check and clean the pressure hose behind the tub.
Next step: Persistent? Book a pressure-switch service.
Code F53
Miele washing machine fault code F53 indicates a speed sensor fault has been detected
What it means: The tachometer that measures drum speed has failed.
DIY check: None.
Next step: A speed-sensor replacement is required.
Code F56
Indicates that the final spin speed is less than 400rpm.
What it means: The final spin cannot reach minimum speed. Often caused by heavy or uneven load.
DIY check: Even out laundry, remove a couple of items and retry.
Next step: If problem continues, have the spin assembly checked.
Code F62
Points to a defective program selector.
What it means: The dial or electronic selector switch isn’t registering changes.
DIY check: Rotate several times through all programmes.
Next step: If no joy, book a selector-knob replacement.
Code F63
Indicates a failure in the water path control unit.
What it means: The central module that directs water flow is at fault.
DIY check: None.
Next step: Requires a specialist water-unit exchange.
Code F65
Suggests that the drum lighting cap is missing.
What it means: In models with drum-illumination, the safety cover is not detected.
DIY check: Insert the cap into its slot and ensure it clicks home.
Next step: If tray or cap is broken, arrange a replacement.
Code F81

Miele washing machine troubleshooting
Miele washing machines have built-in diagnostic tools that recognise when the appliance is experiencing difficulties. Error codes may be accompanied by flashing or solid messages. See a range of troubleshooting implications here:
Washing machine without display
If your washing machine has a blank display and the stop/start button doesn’t light up, it indicates a lack of power. This could be due to a power supply problem, a faulty plug or power socket, or a blown fuse. Another possibility is that the display has automatically switched off to conserve energy. If the fault persists, it is recommended to contact a qualified appliance repair engineer to address any electrical-related issues.
Washing machine inlet/drain light flashing
This flashing light could be caused by various factors, such as a closed stopcock, a clogged water inlet filter, a kinked inlet hose, or low water pressure. Other issues that could trigger this flashing message include improper positioning of the end of the drain hose or obstruction of the drain pump. Additionally, the water protection system may activate and result in this flashing message.
Technical fault with exclamation mark flashing
In this case, it is advisable to switch off the washing machine and disconnect it from the power supply. Seeking professional advice and assistance is crucial for fixing the identified technical fault, which could involve connectivity issues, wiring problems, or control panel difficulties.
An audible signal accompanying Call Service message
This signal indicates that the drum lamp is not fitted correctly and may require repositioning. As accessing the drum lamp involves inserting a lever into the drum lighting slot, it is best to leave this task to the experts.
Other troubleshooting issues that may arise with Miele washing machines include leakage, which could be caused by a damaged door seal or connection problems with the drain hose.
If the leak is from around the door this could be due to a damaged door seal where small items have become trapped. Leaks from under the appliance indicate a connection problem with the drain hose.
