Problem Cause and remedy
Fault426, 526 Wash pressure is too low.
– Wash pressure is too low due to a heavy build-up of
foam. Spilled rinsing agent may not have been cleaned up
after being added.
Follow the instructions regarding foam build-up in
“Chemical processes and technology”.
Start the Rinsing programme in order to clean the wash
cabinet.
– The load carriers were loaded incorrectly or overloaded.
Only use mobile units, baskets, modules and inserts
suitable for the particular application.
Arrange hollow or deep-sided load items so that water
runs off them freely.
– The water lines are clogged or leaking.
Check and clean the filters in the wash cabinet and spray
arms.
Check the injector manifolds for possible leaks, e.g.:
– Are all caps and end caps in place?
– Are all connections fitted with nozzles, irrigation
sleeves, hose adapters or other irrigation connectors?
– Are installed silicone hoses undamaged?
Check the washer’s water connectors in the back panel
of the wash cabinet to ensure that they are attached
tightly, and remove any blockages.
– The amount of water is insufficient for the application.
Increase the amount of water (see “Programme
settings”). If necessary, consult the Customer Service
Department.
Fault433 Protruding load items or other objects, e.g. towels, are
preventing the door from being closed properly by the
Comfort lock.
Remove all objects and sort the load items so that they
do not obstruct the door.
Close the door.
