Problem Possible cause and solution
Fault426, 526 Wash pressure is too low.
– Wash pressure is too low due to a heavy build-up of
foam. Spilled rinse aid may not have been cleaned up after
being added.
Follow the instructions regarding foam build-up in
“Chemical processes and technology”.
Start the Rinse program to clean the wash cabinet.
– The load carriers were loaded incorrectly or overloaded.
Use only mobile units, baskets, modules, and inserts
suitable for the particular application.
Arrange hollow or deep-sided wash 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 the
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 washers in the water connectors in the back
panel of the wash cabinet to ensure they are flush and
remove any blockages.
– The amount of water is insufficient for the application.
Increase the amount of water (see “Program settings”). If
necessary, consult Miele Service.

Fault433 Protruding wash items or other objects, e.g., towels, are
preventing the door from being closed properly by the

Remove all objects and sort the wash items so that they
do not obstruct the door.
Close the door.
