48
Possible cause
The dishes were not
loaded correctly. Dishes
were placed inside other
pieces, water could not
access all surfaces.
The outlet of the water
intake pipe for the middle
spray arm was covered.
An insufficient amount of
water flowed into the
middle spray arm.
The programme was not
powerful enough.
Not enough detergent
was dispensed.
Tall items are blocking the
path of the spray arms.
The spray arm jets are
blocked.
The filter combination in
the base of the wash
cabinet is not clean or is
not correctly fitted.
This may cause the spray
arm jets to get blocked.
The drain pump or
non-return valve may be
blocked.
Remedy
See notes in "Loading the
dishwasher".
Make sure that dishes
placed in the rear section
of the upper basket do not
cover the opening.
Select a more intensive
programme, see

end of these operating
instructions.
Use more detergent, see
"Operating the

Rearrange the items so
that the spray arms can
rotate freely.

arm jets, see "Cleaning
and Care".
Clean the drain pump and
