Miele Washer Error Code F4004

F4004 is an informational code that means the washer's control system is detecting that the door is open or not fully latched. It is not a component failure code but rather a condition notice. The machine will not operate until the door is properly closed and the interlock registers a secured state.

The washer will not start a cycle while F4004 is active, which is by design. The door interlock is a critical safety feature that prevents the drum from spinning with an unsecured door. Do not attempt to bypass the interlock to force the machine to run.

If the fix is simply closing the door properly, there is no cost. If the door latch or interlock switch needs replacement, parts and labor costs typically range from around $100 to $300 depending on your location and service provider. Wiring repairs may fall at the lower end of that range.

Start by firmly pushing the door shut until you hear the latch click, then check if the code clears. If it persists, inspect the door latch, gasket, and hinges for damage or obstructions. If those components look intact, the door interlock switch may need testing or replacement.

A reset will not permanently clear F4004 if the underlying condition, meaning an open or unlatched door, still exists. Because it is an informational status code, it will clear automatically once the control board detects that the door is properly closed and latched. Address the physical or mechanical cause first.
