Maintenance; Cleaning The Drain Pump And Non-Return Valve - Miele PG 8581 Operating Instructions Manual

Cleaning the drain pump and non-return valve

If water has not pumped away at the end of a program there may be
a foreign object in the drain pump or blocking the non-return valve.
Take the filter combination out of the wash chamber (see

Maintenance/Cleaning the filters in the wash chamber").
Open the locking clamp.

Lift out the non-return valve and rinse well under running water.

Make sure that the vent on the outside of the non-return valve is not

blocked (this vent is only visible after the non-return valve has been
taken out). If it is blocked, use a pointed object to release the
blockage.
The drain pump impeller is situated under the non-return valve (see
arrow).
Check the impeller for blockages and remove them if necessary

before refitting the non-return valve.
Carefully replace the non-return valve and secure it with the clamp.
