Cleaning the drain pump and non-
return valve
If the water has not been pumped away at
the end of a wash program (excluding the
Rapid program), there may be a foreign ob-
ject blocking the drain pump or the non-re-
turn valve. These are easy to remove.
 Disconnect the dishwasher from the water
supply and the power supply (switch the
dishwasher off, unplug the electrical plug,
or disconnect or disable the breaker).
 Take the filter combination out of the wash
cabinet (see “Cleaning and care”).
 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 block-
age.
The drain pump is situated under the non-
return valve (arrow).
 Check for foreign objects blocking the
drain pump before replacing the non-re-
turn valve.
 Carefully replace the non-return valve and
secure it with the clamp.
