Two weeks ago I dishwasher stopped working. Replaced the electronic control circuit and everything was working OK until last weekend.
Dishwasher will not fill and start program. Rest of lights on control panel working OK and the dishwasher will run through its cancel/drain cycle ok – just will not start its was cycle.
Tried replacing control panel thinking that the start button was worn. No difference. Have checked that the latch door and fill overflow switch with a multimeter and they seem to be ok and working correctly. Also measured the resistance of the water inlet valve and this seemed ok.
Any ideas on what to check next? Could the replacement electronic box/circuit have already malfunctioned?
Measure the voltage at the fill valve when it should be filling if you have 120 volts AC, then either the valve is toast or the screen filter on it’s input side is clogged.
If it is a clogged screen filter just clean it, as it is there to prevent crud from getting into the valve, holding it open and causing a flood
Thanks for the post. The plot deepens - now have it filling! Water comes in and fills to the correct amount. The machine then “lightly buzzes” for a short while and then empties. The washing part of the program does not start. Yesterday I removed the sump and cleaned it out (down to the cutter blade and fine mesh). The only way I describe is that it sounds like the machine does not want to through the water a round in side (does that make sense).
