I initially replaced the inlet valve sensor which worked for a week. Then the dreaded oe error came back and the dw would not start after the initial fill up and would drain again. I realized this dw is just full of sensors and read inputs and sends outputs. After speaking we the appliances pro, I got the main relay board. Fairly easy to install as ive worked with mother boards and even fixed my own tablet. Seemed to have worked, but we dud get an oe code once this week at the end of a cycle... wasn't there but it was on normal cycle and dishes seemed clean. Wacky dw, bit has nice features. However I think this dw will give more problems...cross my fingers it wont.
