Cleaning The Drain Pump And Non-Return Valve - Miele PG 8080U Operating Instructions Manual

Cleaning the drain pump and
non-return valve
If the water has not been pumped away
at the end of a program, the drain pump
or the non-return valve might be
blocked. They are, however, easy to
clean.
 Disconnect the commercial
dishwasher from the electrical supply
(turn the commercial dishwasher off,
unplug it or disconnect or disable the
fuse).
 Remove the filter combination from
the wash cabinet (see "Cleaning and
care, Cleaning the filters").
 Scoop the water out of the wash
cabinet using a small container.
 Press the catch for the non-return
valve inwards .
 Lift the non-return valve  and rinse
well under running water.
 Remove all foreign objects from the
non-return valve.
The drain pump is located beneath the
non-return valve (arrow).
 Remove all foreign objects from the
drain pump (watch out for glass
splinters which are particularly
difficult to detect and could cause
injury). Turn the drain pump impeller
by hand to check that there are no
more obstructions. You will feel a little
resistance when you turn the impeller.
 Carefully replace the non-return
valve.

Make sure the catch engages
correctly!
Be careful not to damage any
delicate components when cleaning
the drain pump and the non-return
valve.
