Dishwashers that flash the UO error code are frequently experiencing problems with the dishwasher exhaust fan. You can access the dishwasher exhaust fan by removing the 2 mounting screws under your counter holding the dishwasher in place. In this case the dishwasher exhaust fan is located on top of the dishwasher. Check for any broken parts in the fan assembly and make sure that the wiring harness is connected properly. There may be chaffing on the wiring that could be causing the problem. Lastly, it could be the control board itself. In general, the problem will exist at the fan assembly, itself, and will need replacing. Thanks for watching!
