Cleaning the drain pump and
non-return valve
If the water has not been pumped away
at the end of a programme, the drain
pump or the non-return valve might be
blocked. They are, however, easy to
clean.
Disconnect the dishwasher from the
mains supply. Switch off at the mains
socket and withdraw the plug.
Take the filter combination out of the
wash cabinet (see "Cleaning and care
- Cleaning the filters").
Scoop the water out of the cabinet
using a suitable container or utensil.
Press the catch for the non-return
valve inwards
.
Lift out the non-return valve
, and
rinse well under running water.
Remove all foreign objects from the
non-return valve.
The drain pump is situated under the
non-return valve (see arrow).
Remove all foreign objects from the
drain pump (watch out for glass or
bone splinters which are particularly
difficult to detect and could cause in‐
jury). Turn the drain pump impeller by
hand to check that there are no more
obstructions. You will feel a little re‐
sistance when you turn the impeller.
Carefully refit the non-return valve
and secure it with the catch.
Ensure that the catch engages
correctly.
Be careful not to damage any
delicate components when cleaning
the drain pump and the non-return
valve.
