pumped away at the end of a program,
the drain pump or non-return valve may
be blocked. You can remove the
blockage yourself.

the wash cabinet.
^
Flip the fastening clamp to the side.
^
Pull the non-return valve up and out
and rinse it under running water.
,Caution: Use proper eye
protection when removing the
non-return valve.The drain pump is located beneath the
non-return valve (see arrow).
^Before putting the non-return valve
back into place, check that the drain
pump is not blocked.
^Carefully put the non-return valve
back into place and close the
fastening clamp.
For safety reasons, the load should
be washed again.

							Cleaning the filter in the water
inlet
There are filters in the screw connection
of the water inlet hose to protect the
water inlet valve. When the filters
become dirty, they need to be cleaned
so that enough water can flow into the
wash cabinet.
,The plastic housing of the water
connection contains an electrical
component. It must NOT be
submerged in water.Cleaning the filter
^Disconnect from the power supply.
^Turn off the water supply and
unscrew the water inlet hose.
^Clean the large area filter (1) and fine
filter (2) and replace with new filters if
needed.
^Put the filter and seal back into place
and make sure they are sitting
correctly.
^
Reconnect the water inlet valve to the
water valve, making sure it goes on
straight.
^
Slightly open the water tap.
If there is a leak, check that the
connection is on straight and tight
enough.
^
Straighten it to sit correctly, then
tighten and test again.
