Cleaning the drain pump and non-return valve
If water has not been pumped away at the end of a programme there
may be a foreign object in the drain pump or blocking the non-return
valve.
Take the filter combination out of the wash cabinet (see
“Maintenance/Cleaning the filters in the wash cabinet”).
Lift the locking clamp.
Lift out the non-return valve and rinse well under running water.
Make sure that the vent on the external part of the non-return valve
is not blocked. (This vent is only visible when 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.
Carefully replace the non-return valve and secure it with the clamp.
