Hi I have a 6 year old integrated miele dishwasher (G1173 Vi). The pump will not cut out even with the machine switched off, have tried to run a wash but after 10 seconds it beeps and all the six cycle lights flash. I took the machine out of the cabinet and took the sides and base off to see if it was something obvious, run the machine and it worked fine , put it all back and same problem returned. Anyone got any idea what could be causing this?
