Miele Washer Error Code F4041

F4041 means the washer detected that the water temperature was increasing too quickly during the heating phase, indicating the heater power is higher than expected. The machine stops operation as a safety measure to prevent overheating. Possible causes include a stuck heater relay, a faulty NTC temperature sensor, or excessively high supply voltage. A full diagnostic of the heating circuit and related sensors is required to resolve the fault.

No, you should not continue running the washer with F4041 active. The error indicates the heating system is operating outside safe parameters, and continued use risks overheating the water, damaging fabrics, or causing further harm to internal components. Leave the machine off until the fault is diagnosed and corrected.

Repair costs vary depending on which component has failed. An NTC sensor replacement is generally on the lower end of the cost range, while a control board with an integrated relay or a full board replacement can be significantly more expensive. Including labor, total repair costs typically range from around $150 to $500 or more, depending on parts needed and local service rates.

Some basic checks, such as inspecting wiring connections and measuring supply voltage, are within reach of a knowledgeable DIYer with a multimeter. However, replacing the heater relay, control board components, or NTC sensor typically requires disassembling parts of the machine and working near high-voltage components. If you are not comfortable with electrical diagnostics and appliance disassembly, a qualified technician is the safer choice.

A reset may temporarily clear the code, but F4041 will return if the underlying problem in the heating circuit is not repaired. Resetting without fixing the root cause means the machine could overheat again during the next wash cycle. A proper diagnosis of the relay, NTC sensor, voltage supply, and heater element connections is necessary for a lasting repair.
