The power starts to work and looks like it is going to run. As soon as it gets started, it goes off and flashes ER UO over and over. It will not work.
The ER UO error indicates a vent open error. While in wash cycle, Main Control Board does not receive signal from vent assembly that vent plunger is closed. Plunger status is sensed with optical sensor in vent assembly. Check wiring between vent assembly and Main Control Board. If wiring correct, replace vent assembly. If error still exist, replace Main Control Board.
Recently our power went out and when it came back on, our dishwasher is displaying the number 8 only. We've tried to turn off the power for 30 minutes in hope of resetting, but have had no luck. All buttons appear to not be functioning - is there something we can replace to make this guy work again? Thanks!
Answer Steven, Yes, you want to start by replacing the control panel assembly 807545704. It is the more likely issue, based on your description.
The number 8, and the other buttons not working indicates several keypad circuits have failed and are inputting too many circuits and causing the control board to "lock up" and not operate.
