Dish washer not working at all. Signal buzzer stays on all the time. Happened right after a power surge in the house. Disconnected all wiring from module control asm.,plug in only power supply to module and signal buzzer still keeps on ringing. Put new module in dish washer,and still doing the same thing. Checked all wiring and looks good.Really need help on this one. I think I may have gotten a bad module from supply store,but what are the chances of that happening and doing the same thing.
