Zanussi DW24 dishwasher intermittent fill

Washer will fill sometimes on program A and then refuse to fill
on future fill programs unless I tilt the machine to the right
at an angle of approx. 45 degrees.Have cleaned the program
switch contacts with contact cleaner and checked the solenoid
valve for correct operation and all seems ok.Any clues ??

Basically the antiflood device on your machine is being activated. There are several things that can cause this, from a faulty valve to blockage in the system or at worst a choked IWMS (water management system, large plastic thing on the left hand side of the machine).
Realistically it's pretty well much time to call in an engineer to diagnose.



Unplug your appliance before working on it.
