What the F11 error means

The F11 error code indicates that your Miele dishwasher has detected a problem with the drain pump or drainage system. This error typically appears when the dishwasher cannot remove water from the tub within the expected time frame, or when the drain pump itself has failed. The dishwasher’s control board triggers this error to prevent flooding and protect the internal components from water damage.

Common causes

  • Clogged drain filter or sump area with food particles, broken glass, or debris
  • Blocked drain hose due to kinks, twists, or internal obstructions
  • Faulty drain pump motor that has burned out or seized
  • Obstructed drain pump impeller caused by foreign objects like toothpicks, labels, or small utensils
  • Defective drain pump wiring or electrical connections
  • Blocked household drain or garbage disposal preventing proper water evacuation

How to fix the F11 error

  1. Check and clean the drain filter: Turn off the dishwasher and open the door. Remove the lower dish rack and locate the cylindrical filter assembly at the bottom of the tub. Turn the filter counterclockwise to remove it, then clean out any food debris, broken glass, or foreign objects. Rinse the filter under running water and reinstall it by turning clockwise until it locks into place.
  2. Inspect the drain pump area: After removing the filter, check the sump area beneath it for any debris or obstructions. Use a flashlight to look for small items that may have fallen through. Remove any visible blockages and wipe the area clean with a damp cloth. Ensure the drain pump impeller can spin freely by gently rotating it with your finger.
  3. Examine the drain hose: Pull the dishwasher out from under the counter to access the back panel. Locate the drain hose (usually corrugated and connected to the drain pump). Check for kinks, twists, or compression points that could restrict water flow. Disconnect the hose from both the pump and the drain connection, then flush it with water to clear any internal blockages. Reconnect securely.
  4. Clear the garbage disposal or sink drain: If your dishwasher drains into a garbage disposal, ensure the knockout plug was removed during installation and that the disposal isn’t clogged. Run the disposal with hot water for 30 seconds. If connected to a sink drain, check that the drain isn’t blocked with grease or debris.
  5. Test the drain pump: If the above steps don’t resolve the issue, the drain pump may be defective. Access the pump by removing the lower spray arm and filter assembly. Disconnect power to the dishwasher, then disconnect the wiring harness from the pump. Check for continuity using a multimeter (should read 50–200 ohms). If there’s no continuity or visible damage, replace the drain pump assembly (cost: $80–$150).
  6. Reset the dishwasher: After completing repairs, reset the error code by turning off the dishwasher at the circuit breaker for 5 minutes, then restore power. Run a rinse cycle to verify proper drainage and confirm the F11 error has cleared.
