Possible cause
203
No change detected by the level
switch during emptying
Boost pump defective
Booster pump plug connector loosened
Start capacitor defective
Plug connector loosened

Following the end of post-rinse
time, still no change detected
at the level switch
See 203
205
Temperature increase not
reached

206
Wash time increase
Boiler not ready for rinsing early enough
(boiler level/ boiler temperature)
Boiler heating defective / thermal fuse

Actual boiler temperature too high Contactor sticking
Incorrect sensor / defective sensor
Check sensor / cable (contact plug
