We are having problems with our zanussi da6141 dishwasher, it works on rinse hold, but when you set it to A it goes through the cycle upto point B, then gets so far round and keeps running, the knob stays in the same position for ever! Ive done a little research and brought the 56 degree thermostat, fitted it and tested it. And it still does the same. Has anyone have any ideas on what eels I can test?

rather difficult to go further remotely. could be temp sensor. another place to look is at the module - have known quite frequently dry joints at the heater output. examine it carefully

Hello Paul, The first thing to try is to clean the filters at the rear pipe(s) that connect to the main water supply. It is quite common that when the water-flow is impeded, the programs may stop with flashing lights depending on the rate/amount of blockage.
So, pull out the unit and disconnect the rear pipe and give the in-line filters(s) a good going-over. Please let me know if this does the trick...
Best Regards,

Peter...
