Below, we break down the most common Miele washer error codes, translate what they mean in plain English, and provide actionable fixes to get your appliance running again.
Key Takeaways
- Identify the issue: Miele error codes act as a diagnostic tool, pointing directly to problems like drainage blockages (F11) or water intake faults (F10).
- DIY solutions first: Many faults, such as excessive foam (F16) or trapped debris, can be fixed by cleaning filters, checking hoses, or adjusting detergent use.
- Know when to call a pro: Electronic failures (F40-F50) or motor issues usually require a certified technician and specific replacement parts.
- Safety is priority: Always turn off and unplug your machine before attempting any manual inspections or repairs.
Troubleshooting Miele Washing Machine Problems
Before diving into the specific codes, it helps to know the most frequent offenders. Miele washers often run into issues with machines not spinning, failing to drain, or activating the “Waterproof System” due to leaks.
Understanding these Miele washer fault codes empowers you to handle minor maintenance yourself. This guide helps you decipher the digital display so you can decide if it is a quick DIY fix or if you truly need to pay for a service call.
Miele Washer Error Codes
Your machine communicates through these codes. Here is your cheat sheet for interpreting the alerts and fixing the underlying issues.
F1 or F2 Error Codes
What It Means: The NTC (temperature) sensor has short-circuited. This relates to how the machine reads water or heating temperatures.
How To Fix It: Check the wiring connected to the sensor for any loose plugs. If the wiring looks fine, the sensor itself is likely faulty and needs replacement.
F10 Error Code
What It Means: Water intake is blocked or restricted.
How To Fix It: Ensure your home’s water supply valve is fully open. Inspect the intake hose for kinks or heavy objects resting on it. You should also check the mesh filter inside the water inlet valve; if it is clogged with sediment, clean it out carefully.
F11 Error Code
What It Means: Drainage fault. The water cannot leave the machine.
How To Fix It: This is one of the most common errors. Your washing machine is not draining because of a blockage. Open the access panel (usually bottom left), drain the water using the small tube, and unscrew the drain filter. Remove any coins, buttons, or lint blocking the impeller. If the filter is clear and the hose is not kinked, the drain pump itself may be dead.
F12 Error Code
What It Means: Water intake fault detected immediately at the start of a cycle.
How To Fix It: Verify the water supply is turned on. If the water pressure in your home is too low, the machine may time out before it fills.
F13 Error Code
What It Means: Water intake fault related to the heater pressure switch.
How To Fix It: This is often a component failure. Inspect the water intake valve and replace it if necessary.
F14 Error Code
What It Means: Heater pressure switch fault.
How To Fix It: This switch ensures there is enough water before the heater turns on. Check the wiring connections and the circulation pump capacitor. If these are functional, the pressure switch itself likely needs swapping out.
F15 Error Code
What It Means: Hot water intake fault.
How To Fix It: Ensure your hot water valve is open. If you only have a cold water connection, ensure your machine is programmed to “cold fill” mode so it doesn’t search for hot water that isn’t there.
F16 Error Code
What It Means: Excessive foam (oversudsing).
How To Fix It: You likely used non-HE detergent or too much of it. The machine struggles to spin when there is too much foam. Run a rinse cycle without detergent to clear it. In the future, reduce your dosage or switch to a high-efficiency detergent.
F19 Error Code
What It Means: Flow meter is stiff or stuck.
How To Fix It: The component that measures water volume isn’t spinning freely. You will typically need to replace the flow meter or the entire water intake assembly.
F20 Error Code
What It Means: Water is not heating up.
How To Fix It: This indicates a heater element failure or a bad relay. Inspect the heating element for continuity with a multimeter. If it is open (no continuity), replace the heating element.
F24 Error Code
What It Means: Heater relay contact is stuck or faulty.
How To Fix It: The relay that controls the heater has likely fused together or suffered moisture damage. Replace the heater relay.
F25 Error Code
What It Means: Target temperature not reached.
How To Fix It: This can be a bad heater relay, but it is also caused by excess suds insulating the water sensor. Ensure you aren’t overdosing detergent. If suds aren’t the issue, check the heater relay plug for corrosion.
F26 Error Code
What It Means: Boiling protection triggered. The sensor detected heat above 194°F (90°C).
How To Fix It: This is dangerous for your clothes and machine. It usually means the heater relay is stuck in the “on” position. Check the relay and the NTC temperature sensor.
F29 Error Code
What It Means: Steam heating element is inactive.
How To Fix It: If your model has a steam function, the dedicated heater for it has failed. Replacement is required.
F34 Error Code
What It Means: Door locking mechanism failure.
How To Fix It: Check for clothes trapped in the door seal. Clean the door latch area with rubbing alcohol to ensure the sensor can read the magnet. If the door clicks but won’t lock, the interlock mechanism needs replacing.
F39 Error Code
What It Means: Electronic unit fault (BAE).
How To Fix It: This is a main control board issue. It is rarely a DIY fix unless you are comfortable replacing circuit boards. Contact a technician.
F40 Error Code
What It Means: General electronic unit fault.
How To Fix It: Similar to F39, the brain of the washer is glitching. It may require a firmware update or a board replacement by a pro.
F41 Error Code
What It Means: Data transfer error; cycle aborted.
How To Fix It: This is a software glitch. Turn the machine off, unplug it for 60 seconds, and plug it back in. If the error persists after a hard reset, the control board may be defective.
F42 Error Code
What It Means: Mains frequency error.
How To Fix It: The machine isn’t reading the electrical frequency (50Hz/60Hz) correctly. Verify your home’s power supply is stable. If other appliances are fine, the washer’s power unit is faulty.
F43 Error Code
What It Means: Model type not programmed.
How To Fix It: The control board has “forgotten” which machine it is installed in. A service technician must connect a laptop to reprogram the unit.
F45 Error Code
What It Means: Flash RAM defective.
How To Fix It: Memory failure on the main circuit board. The electronic module needs replacement.
F46 Error Code
What It Means: LCD display connection fault.
How To Fix It: The wire connecting the main board to the screen is loose or broken. Open the top panel and check the ribbon cables.
F47 Error Code
What It Means: Interface BAE/SLT defective.
How To Fix It: Another communication error between internal boards. Requires professional diagnostic tools.
F50 Error Code
What It Means: Drive error; motor not turning.
How To Fix It: Check if the drum is physically stuck by rotating it by hand. If it spins freely, the issue is likely the motor or the inverter board.
F51 Error Code
What It Means: Pressure switch fault.
How To Fix It: The sensor that detects water levels is sending bad signals. Inspect the small rubber hose connected to the pressure switch for holes or blockages before replacing the switch.
F52 Error Code
What It Means: Heater pressure switch reset during heating.
How To Fix It: Often caused by excessive suds lifting the water level sensor. Run a clean cycle. If suds aren’t present, the pressure switch is defective.
F53 Error Code
What It Means: Speed sensor (Tacho) fault.
How To Fix It: The machine cannot tell how fast the drum is spinning. This is usually a loose magnet on the motor shaft or a faulty tachogenerator coil.
F56 Error Code
What It Means: Spin speed not reaching 400 RPM.
How To Fix It: The motor is struggling. Check the carbon brushes (if your model has them) for wear. If they are worn down, replace them. Otherwise, check the tachometer coil.
F62 Error Code
What It Means: Program selector switch is defective.
How To Fix It: The knob you turn to select cycles is broken or disconnected electronically. The selector unit needs replacing.
F63 Error Code
What It Means: Water path control unit fault.
How To Fix It: Issues with the diverter that sends water to the detergent drawer vs. the drum. Inspect the diverter mechanism for jams.
F65 Error Code
What It Means: Drum light fault.
How To Fix It: The light inside the drum isn’t working. Check the bulb and the connector tab. It won’t affect the wash performance, but it is annoying.
F67 Error Code
What It Means: Circulation pump speed too low.
How To Fix It: The pump that sprays water over the laundry is clogged. Remove the filter and check the pump impeller for hair, lint, or debris.
F68 Error Code
What It Means: Circulation pump running when it shouldn’t.
How To Fix It: An electronic relay on the control board has fused shut, keeping the pump powered constantly. The board or relay requires replacement.
F69 Error Code
What It Means: Circulation pump blocked.
How To Fix It: Similar to F67, but the pump is completely seized. Take the pump apart and clean it thoroughly. If it still won’t spin, replace the pump.
F70 Error Code
What It Means: Waterproof System (WPS) activated.
How To Fix It: This is a critical safety feature. Water has leaked into the base pan of the machine. The float switch has triggered to stop flooding. Turn off the water supply immediately. Tilt the machine (carefully) to drain the base pan, then hunt for the leak source, usually a loose hose or door seal.
F81 Error Code
What It Means: Steam heater fault.
How To Fix It: The steam generation unit isn’t working. Check the thermal fuse on the steam heater unit.
F83 Error Code
What It Means: Steam heater overheating.
How To Fix It: The electronic thermostat meant to regulate steam temperature has failed. Replace the power electronic or steam unit.
F92 Error Code
What It Means: Bacterial contamination risk.
How To Fix It: You have been washing at low temperatures for too long. Mold or bacteria is building up. Run a “Sanitize” or “Clean Machine” cycle with hot water (above 165°F) and a machine cleaner.
F138 Error Code
What It Means: Water detected in the drip tray.
How To Fix It: This is essentially the same as F70. The leak protection system is active. Dry the tray using a sponge or towel and inspect internal hoses for leaks.
F220 Error Code
What It Means: Water supply fault.
How To Fix It: Similar to F10. The machine isn’t getting water fast enough. Check that the tap is fully open and the inlet hose isn’t kinked behind the machine.
How to Reset Miele Washing Machine
Sometimes the computer just needs a reboot. Not all Miele washers have a dedicated “Reset” button. If yours does, it is typically near the display screen. Press and hold it.
If you don’t have a button, try this hard reset method:
- Turn the program dial to the “Off” or “Stop” position.
- Unplug the machine from the wall (or flip the breaker) for at least 5 minutes.
- Plug it back in and turn it on. Open and close the door firmly to re-engage the latch.
- Select a “Drain/Spin” cycle to test if the error clears.
FAQs
Do Miele Washing Machines Need Servicing?
Yes, regular maintenance is vital. While Miele machines are built to last, ignoring manufacturer guidelines, like cleaning filters or descaling, can invalidate your warranty and lead to premature breakdowns.
How Long Are Miele Washing Machines Guaranteed For?
Most Miele washing machines come with a standard 1-year or 2-year manufacturer warranty, depending on your region. However, Miele is famous for engineering machines to last 20 years, and they often offer extended 5-year or 10-year warranty packages for purchase.
