Safe checks, step by step

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.

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.

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.
