Miele Dishwasher Error Code F75 — Drain Pump Blocked or Seized
What this means
Error F75 indicates that the drain pump specifically has failed to operate — either it is mechanically blocked or the motor has seized. Unlike F11 which broadly covers drainage issues, F75 is triggered when the control board sends power to the drain pump but detects no rotation or current draw inconsistent with normal operation. Food debris, broken glass, or a failed pump motor are common causes.
Alternate codes: F 75
Step-by-step fix
4 stepsDrain standing water manually
If the tub is full of water, scoop it out with a cup or use towels. Remove the drain filter and coarse filter to access the drain pump area.
Lay towels on the floor around the dishwasher — there may be residual water that flows out when you open the filter area.
Clear the drain pump
Locate the drain pump cover in the sump. Remove it and check for debris blocking the impeller. Remove any foreign objects. Try spinning the impeller manually — it should rotate freely in one direction.
The drain pump impeller on Miele dishwashers is designed to rotate in one direction only. Do not force it backward.
Test the drain pump motor
Unplug the dishwasher and access the drain pump from below. Disconnect the pump electrical connector and test the motor windings with a multimeter. Typical resistance is 100–300 ohms.
If the motor reads open-circuit, the windings have burned out and the pump must be replaced.
Replace the drain pump if needed
If the pump motor is electrically dead or the impeller shaft is seized in its bearing, replace the entire drain pump. It is typically held in with a bayonet twist-lock or 2–3 screws. Disconnect the hose and electrical connector, swap in the new pump, and reassemble.
When installing the new pump, ensure the hose clamp is tight to prevent a leak that could trigger F70.
When to call a professional
If the drain pump tests fine electrically but still does not run when the dishwasher commands it, the control board triac that drives the pump may have failed, requiring professional board repair.
