Model w10311121b no power
Hi Scott. It appears you have the same dishwasher as mine bought in 2010- it worked sporadically for several years. I bought one year warranty ($289) in Feb2014 . Over 2 months, service technicians replaced 3 parts (user control board, motor control board and water sensor) hoping that each would fix it. They told me to run hot water before starting a wash cycle. Dish washing cycle failures were still sporadic and it finally lost all power in May2014. Service techs would not come out so I confirmed house power supply with a multimeter and then took the door apart to access the latch. I determined the latch kill circuit was not assembled properly and it had carbon buildup which I scraped off.
If your warranty has ended and you attempt this, do not use a power screw driver with these Torx screws as you can easily strip the threads or damage the plastic user control housing by screwing in too far on the top screws. (especially if you forget to reinstall the internal handle which acts as a spacer).
To disassemble: Remove the top 4 screws and top side screws, loosen the middle and lower side screws as needed. Separate the washer door face wide enough to remove the user control board, let it hang by the cord. The handle will be loose in the way, remove it. The latch has a white plastic kill circuit which is held to the latch with tabs. Unplug the circuit and carefully remove it. The circuit comprises 2 flat metal sheets that are pushed together by the latch lever when the door is shut. These plates separate when the door is open to kill washer power. The latch lever should be under both circuit plates with the shorter plate on the bottom. (long plate, short plate, lever, white housing). Reassemble, remember to include the handle My dishwasher operates properly now.
