TROUBLESHOOTING

6. Troubleshooting

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

customer is using the right amount. Most

importantly 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 29).

• Check that the gauge block on the left side

of the bottom drain by the drain pump is in

place.

• Check that the machine heats to the right

temperature.

6.2 Common faults

If the dishwasher does not work, you

should rst 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,

rst 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 drain hose blocked? Check the con-

nection to the household drain.

• Is the drain hose bent?

• Are the lters blocked?

• Is the drain pump blocked?

• Is the gauge block on the left side of the

bottom drain by the drain pump incor-

rectly tted?

If the fault cannot be found with the help of this

chapter, open the service menu and perform an

function test on all components.
