Miele Washer Error Code F4141

F4141 means the washer detected a problem with its heating circuit during the heating phase of a wash cycle. The machine checks that both heating-dry protection contacts close and that the NTC sensor registers a minimum 5 degree Celsius temperature increase within 3 minutes. If either condition is not met, the fault is stored and displayed. The likely causes include failed heater relays, faulty protection contacts, a bad NTC sensor, or a problem with the level switch.

No, you should not continue running the washer with this fault active. The F4141 code indicates the heating system is not operating correctly, and continuing to run the machine could result in incomplete wash cycles or potential electrical issues. The washer should be inspected and repaired before further use.

Repair costs depend on which component has failed. Replacing a heater relay or NTC sensor is generally less expensive, typically in the range of 100 to 250 dollars including labor. If the heating element or a more complex control component requires replacement, costs can rise to the range of 250 to 500 dollars or more. Getting a diagnostic visit from a Miele-authorized technician will provide a firm estimate for your specific situation.

Some diagnostic steps, such as checking for obvious wiring damage or testing the level switch, can be performed by a knowledgeable DIYer with a multimeter. However, testing heater relays 1K1 and 2K1, the heating-dry protection contacts, and the NTC sensor requires comfort with disassembly and electrical measurement. Replacing relays or internal control board components is generally better suited to a qualified technician.

A reset may temporarily clear the fault display, but it will not resolve the underlying problem. If the heating-dry protection contacts, relays, NTC sensor, or level switch have a genuine defect, the fault will return as soon as the machine attempts to heat water again. A reset is only useful for confirming whether the fault is intermittent or persistent.
