Miele washing machine error codes

Even the most reliable household appliances can malfunction over time due to component wear and tear or external influences. Miele washing machines feature self-diagnostics and, if any malfunctions are detected, display an error code on the display. To help you understand the meaning of the letter and number combinations displayed, we've provided a detailed description of Miele washing machine error codes.

Heating problems

To repair and troubleshoot a malfunction, you need to know what steps to take when a specific error occurs. Let's start by looking at the codes displayed when thermostats and heaters fail.

F01 indicates a faulty drying temperature sensor. This can be caused by a short circuit in the thermistor that monitors the temperature in the drying chamber. This can be resolved in two ways: by completely replacing the part or repairing the damaged wiring.
F02, F03, F04 indicate that there are some problems with the drying temperature sensor. There may be a disconnection in the thermostat connecting wires, a short circuit in the connecting circuit, or a broken sensor. To correct the situation, you should test all contacts between the thermistor and the module; if working with the connections does not help, replace the element with a working one.
F20 indicates a malfunction in the water heating system in the drum. The washing machine's heating element and temperature sensor should be checked for functionality. If one of the components is defective, it should be replaced.
F29 indicates that the dryer's heating element is not functioning. The heating element needs to be replaced immediately.
F83 indicates that the temperature in the drying chamber has exceeded the permissible limit. The thermistor and heating element should be checked for functionality; if faulty, replace the parts.

Before you begin repairing your Miele washing machine, be sure to turn off the power to the appliance and disconnect it from the house utilities.

Problems with temperature sensors or heating elements in automatic washing machines are easy to fix yourself. Before attempting any repairs, be sure to review the detailed instructions.

Problems with filling and draining water

In some cases, problems with water intake or wastewater drainage may occur. Error codes will alert you to these issues: Error codes related to water filling

F10 detects a problem with filling the tank with water. This could be caused by a clogged inlet hose, problems with the main control module, or a blocked shut-off valve. Depending on the cause, the solution may be opening the inlet valve, cleaning the hose, or diagnosing the control board.
F11 indicates that the water is not draining. This could be due to a clogged drain hose, filter, or pump, or low water pressure in the plumbing system. Check the water pressure; if it's normal, clean the drain hose, pump, and filter.
F15 indicates that the tank is filling with hot water. Check that the inlet hose is connected correctly.
F19 indicates a faulty water level sensor. Inspect the pressure switch; a foreign object may have lodged itself.
F51 indicates the need to replace the pressure switch.
F96 warns that the alternative water supply is not turning on. This error can be resolved by checking the relevant components.

Once you've identified the cause of your washing machine's malfunction and sorted out the root cause, you can restore the unit's functionality yourself, without calling in a professional for repairs.

Hatch door malfunctions

Two codes indicate problems opening and closing the sunroof. F34 indicates the sunroof is not closing properly. This could be due to worn door components (such as the lock, handle, or latch), or a faulty sunroof locking mechanism. Replace any broken components.

F35 states that the hatch cannot be opened. Most likely, there is a blockage in the keyhole, or a malfunction in the electronic board. Carefully open the hatch and clean the lock. If this isn't the issue, repair the control board.

Repairing the main control board requires certain skills and knowledge, so it is better to invite a specialist to carry out the work.

The electronics are faulty

If your Miele washing machine experiences any electronic malfunction, the following digital combinations will appear on the display:

F39, F41, F43, F45, and F50 indicate a failure of the main control module. Repairing or replacing the control unit can resolve the issue.
F46 warns that the display is not connected correctly. The wires may be broken or the control board may be damaged. Repairing or replacing the components can resolve the issue.
F47, F48 indicate problems with the BAE/SLT interface.
F55 warns that the element that controls the washing machine's operating time is not functioning correctly. To resolve the issue, the element needs to be replaced.
F62 indicates that the washing program selector handle is faulty and requires installation of a new selector.
F65 indicates that the drum backlight is faulty.
F93 indicates a defect in the auxiliary unit relay, which means the part needs to be repaired or replaced.
F100 indicates a disruption or complete interruption of communication with IK6. Diagnostics and repair of the connection components are required.

By taking into account the error codes in your washing machine's electronics, you can independently determine the cause of the machine's malfunction. And if you have sufficient washing machine repair skills, you can even repair the machine yourself.

Other codes

When using the machine, the following symbols may suddenly appear on the display:

F16 indicates a large amount of foam in the drum. This could be due to overdosing on detergent or a malfunctioning drainage system. Check the waste water drain hose and pump for blockages. You can remove foam by running the “Rinse” mode.
F53 indicates a faulty drum speed sensor. The part will need to be replaced.
F56 will indicate that the drum speed is significantly low, below 400 revolutions per minute. Most likely, the engine tachometer is faulty; check this component.
F63 indicates that the water flow control system is not functioning properly. The system should be checked and repaired if necessary.
F64 indicates damage to the trajectory sensor; the part must be replaced.
F92 warns of a high risk of fungal damage to the inside of the machine. It is necessary to immediately activate the self-cleaning mode for the drum surface or clean it manually.

Knowing the meaning of each Miele automatic washing machine error code will help you better understand any problems with the system. While some problems can be repaired yourself, it's best to call a professional for repairs and replacements of complex and serious parts.
