Frigidaire dishwasher error code UO – How To Fix
THE VENT AND FAN ASSEMBLY ARE LOCATED ON THE TOP BACK RIGHT CORNER OF THE DISHWASHER TUB.
The vant and fan opens to assist to dry the dishes at the end of the washing cycle.
If the control board senses that the vent is open it will not start the wash cycle.
The Frigidaire manual advises to check the wiring harnesses and all connections.
If you find the wiring and all connections to check out good, then replace the vent assembly.
If the error code uo comes back, then replace the main control board.

Where is vent assembly on Frigidaire dishwasher? I’m getting error code UO or uo.
Rudy R,
If the main board in your dishwasher has a shorted area or “closed” circuit on it, it may be supplying power to the Frigidaire dishwasher pump motor at all times.
Replace the main board and this should solve your issue.

Frigidaire dishwasher #FiGD2466QF4A control panel shows dishes are clean however pump motor still running. There is still some small amount of water in sump under the filter screen. Turned power source to dishwasher off for 40 min to see if maybe display board will reset itself to no avail. Pump still on with dishwasher off. I believe its the motherboard but i wanted to get a second opinion.
Mike,
The control board may be faulty or the keypad may be stuck on your Frigidaire dishwasher.
Be sure the door switch is in working order because if not the dishwasher may think the door is open if the door switch is faulty.
Use a meter to be sure.
If the door switch is in working order and the dishwasher still does nothing, then you may have a faulty control board.
Also be sure it is not something simple such as a loose wire or wire harness before replacing the main control board.

My frigidaire dishwasher will let me select normal cycle but when I push the start/cancel button, nothing happens, I ran jumper wires between the wires on the switch connecting black to black and white to white, but it still doesn’t start up, then when I try to put it in test mode after unplugging the dishwasher and holding on the the air dry and start cancel bottons, nothing happens at all, what do you think the problem might be?
Larissa,
Frigidaire dishwasher displaying code i30 = Water leak or overflow in bottom drain pan.
CHECK FOR WATER LEAKS – CHECK HOSES AND PUMP
Frigidaire dishwasher displaying code i40 = Clogged filters or drain line plugs or pinches.
CHECK TO BE SURE DRAIN LINE IS NOT CLOGGED
Try a reset by pressing the High-Temp and Start-Cancel buttons on the dishwasher and hold them for about 10 seconds.
