6.1 Dishwashing results

Check the following points if the dishes are not
clean (always begin by checking any fault codes
and the most recent fault indication in the
service menu):
• That the customer is using the right dishwash-
ing program.
• If heavily soiled dishes are being loaded, such
as pots or oven dishes, choose a heavier pro-
gram.
• Check that the customer is using a suitable
dishwashing detergent, preferably one with
proven good results.
• Detergent is a perishable product. Check that
the detergent is not too old and that the cus-
tomer is using the right amount. Most impor-
tantly not too much detergent.
• For machines with a water softener, dose as for
soft water.
• Check that the customer is loading the ma-
chine correctly.
• Check that no dishes are preventing the spray
arms from rotating and that the holes are not
clogged.
• Check that the machine has the right water
level (see page 9).
• Check that the gauge block on the left side of
the bottom drain by the drainage pump is in
place.
• Check that the machine heats to the right
temperature.
Film or marks on dishes after washing
• Is the water softener cover properly tightened?
• Is the rinse aid dispenser correctly adjusted?
• Is the water softener correctly adjusted?
• Is there any salt in the salt compartment?
• Is the right type of salt being used?

6.2 Common faults
If the dishwasher does not work, you should
first check whether this is due to a simple fault,
something that the customer can rectify. Use
the following questions to troubleshoot the
machine.
The machine will not start
• Has a fuse blown?
• Is the machine powered?
• Is the door properly closed?
• Is the water supply turned on?
If the answer to any of the above questions is
"YES" and the machine seems to lack power,
first check that there is power at the main
power switch and the control unit. Replace
any faulty components.
Water remaining in the machine
• Is the drainage hose blocked? Check the con-
nection to the household drain.
• Is the drainage hose bent?
• Are the filters blocked?
• Is the drainage pump blocked?
• Is the gauge block on the left side of the bot-
tom drain by the drainage pump incor-
rectly fitted?
If the fault cannot be found with the help of this
chapter, open the service menu and perform an
function test on all components.
