Risk level

Proceed carefully and stop if the check is unclear.

Urgency

High

Quick answer

F11 with water left in the wash cabinet means the documented Miele dishwasher has not drained correctly. Disconnect power and identify the family before checking the accessible drain area.

Safety first

Stop and check this first

  • Disconnect power before opening the drain area and take particular care because broken glass may be hidden inside the drain pump.

Safe checks you can perform

  • Confirm the dishwasher family
  • Disconnect power and remove standing water
  • For G1xxx-G6xxx, clean the non-return valve and pump area
  • For G7xxx/G5xxx Discovery, clean the drain-pump area
  • Refit the family-specific parts and test once

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Diagnose a persistent F11 drain fault

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Diagnose a persistent F11 drain fault

    What they doMiele Customer Service or a qualified appliance technician should inspect the drainage system when F11 returns after the documented accessible cleaning.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Confirm the dishwasher family

    No special tools

    Identify whether the dishwasher is G1xxx-G6xxx or G7xxx/G5xxx Discovery before opening the drain area. The two groups use different access parts and refitting steps.

    Do not interchange the non-return-valve procedure with the drain-pump-cover procedure.

  2. Disconnect power and remove standing water

    No special tools

    Switch the dishwasher off and unplug it. Follow the guide for the identified family: G7xxx/G5xxx Discovery also requires removing the lower spray arm before the filter combination. Scoop standing water out with a small container.

    Keep the appliance disconnected while the drain area is open.

  3. For G1xxx-G6xxx, clean the non-return valve and pump area

    No special tools

    Release the non-return valve as shown in the matching Miele guide. Rinse the valve and carefully remove only visible foreign objects from the pump area. Check that the impeller can turn without forcing it.

    Broken glass can be difficult to see. Protect your hands and do not probe blindly or dismantle internal parts.

  4. For G7xxx/G5xxx Discovery, clean the drain-pump area

    No special tools

    Follow the newer-family guide to release the drain-pump cover, remove only visible foreign objects and check the impeller without forcing it. Refit the cover in the documented position.

    Broken glass can be difficult to see. Protect your hands and do not probe blindly or dismantle internal parts.

  5. Refit the family-specific parts and test once

    No special tools

    Refit the valve or pump cover exactly as shown for the identified family, then reinstall the filters and any removed spray arm. Run one wash programme to check whether the water is pumped away.

    Stop the test if water leaks or the pump makes an abnormal mechanical noise.
