Miele Dishwasher Error Code F80 — Circulation Pump Blocked or Faulty
What this means
The F80 error code on Miele dishwashers indicates the main wash pump (circulation pump) is blocked, seized, or not running at the expected speed. This pump drives water through the spray arms during wash and rinse cycles. A jammed impeller from glass shards or food debris, a burned-out pump motor, or a failed capacitor can trigger this code. Without the circulation pump, dishes will not be cleaned.
Alternate codes: F 80
Step-by-step fix
4 stepsCheck for blockages in the sump
Open the dishwasher and remove the lower rack, lower spray arm, and the triple filter assembly. Look down into the sump area for broken glass, bones, or other debris that could be jamming the circulation pump impeller. Remove any foreign objects.
Miele dishwashers have a fine mesh filter that catches most debris, but small items like broken glass pieces can slip past.
Inspect the spray arms
Remove the upper and lower spray arms and rinse them under water. Check that the spray holes are clear and not clogged with food residue or mineral deposits. Blocked spray arms increase pump back-pressure and can trigger this error.
Soak the spray arms in warm water with white vinegar for 30 minutes to dissolve mineral deposits.
Reset the dishwasher
Turn off the circuit breaker for 10 minutes. Restore power and run a normal cycle. If the pump was temporarily stuck due to debris, clearing it and resetting may resolve the issue.
If the pump makes a loud humming or grinding sound when the cycle starts, the impeller is likely still obstructed.
Test the circulation pump motor
Turn off the breaker. Access the circulation pump from underneath the dishwasher. Disconnect the pump motor wires and test for continuity with a multimeter. Also check the pump capacitor if accessible. Replace any failed components.
Miele circulation pumps are typically a sealed unit. If the motor has failed, the entire pump assembly is replaced.
When to call a professional
Miele dishwasher circulation pump replacement requires specialized knowledge of Miele's assembly. A Miele-certified technician is recommended for pump motor replacement.
