How to fix Miele dishwasher error code F11 (safe owner checks)

Safety first: disconnect power before you remove any panel or reach into the sump or drum. Do not touch wiring, the control board or the motor. If you see water near electrical parts, stop and call a technician. These steps are based on Miele's published guidance [1], rewritten for clarity.

Unplug. Switch off and unplug the dishwasher.
Remove filters and water. Take out the filter combination and scoop out the water.
Clean the non-return valve. Press its catch in, tip it to release the cover, and rinse it under running water. Watch for glass splinters.
Clear the pump. Push a small sponge through the impeller, remove foreign objects, and turn the impeller by hand.
Reassemble. Refit the valve vertically so it's flush with the catch engaged, lay the filters flat, and restart.
