Question

Re; Smeg DWD612CSS dishwasher. Please help.On setting our dishwasher to operate overnight, we were awoken by a loud bang only to find a strong rubber burning smell and the trip had blown. After investigating we found that the part no DWF 409 interface filter required replacing which we have done. Now however the dishwasher runs to the middle of its cycle and stops. The troubleshooting page of the manual tells us code E3 applies i.e.first 2 phase lights are lit and states "The appliance is not able to pump out water", but the machine is empty of water. It would also appear to be cold inside so we assume that it has not been able to heat the water during the wash. Any ideas to help with this problem will be very gratefully recieved. Pete
