Question about Frigidaire Dishwashers
Fills then error code UO flashes
You are experiencing a vent issue - 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.

The problem you are having is the vent assembly blower part number 154562802 for 4000 series aquasurge dishwashers by Frigidaire. The service manual will tell you to replace this part but it can be fixed in most cases. This part is located on the top, right back of the tub. You will have to remove the unit from the cab to get access. Remove the part and disconnect the wires. There are two fasteners on the cover of the vent assy unit with the note "Do not remove cover no serviceable parts". Inside you will most likely find the rubber valve clogged up preventing the valve from closing enough for the pickup to break the contacts with the switch board. I would recommend removing the rubber value from the unit by pulling the wire clip pin. Clear the rubber valve and reinstall. Make sure you have the valve in the correct position and reinstall the pin and fan and replace the cover and reinstall the vent assy. You should be good to go for another year or so until the build up needs to be cleaned again. This is a very poor design by Frigidaire.

SOURCE: Error code ER then UO any ideas?
So far so good. I fixed mine by removing the vent and even though it says no repairable parts I disassembled it then removed the rubber gasket and cleaned it with a brush under hot water. I then cleaned the plastic ring it seals against. Next I removed the spring and stretched it to make it about a quarter inch longer and then reinstalled the spring then the rubber gasket and then closed up the unit. So far it is working fine. I suspect the real problem is that there is a tiny sensor that needs to be covered when the vent is closed. If this is not covered the uo error code is generated.

this is a vent problem you need to check the vent motor and make sure tha the wire have not been pinched by the door spring and make sure it is connected properly.the vent should be located on the top or possibly the right side of the cabinet.

Good Afternoon Jean, thanks for your inquiry!
I understand that your Frigidaire dishwasher is displaying an error code of "E R U O". From the code you provided it sounds like the code is "UO" which means the vent is open. This could be a possible issue with your vent assembly, wiring harness, or control panel. I would suggest checking the vent assembly to assure it is opening and closing. If the vent is working properly I would advise you to perform a reset on your dishwasher and you can do that by flipping the household circuit breaker off for at least ten minutes. If this does not resolve your issue I would recommend having a professional technician out to perform proper repairs. This will prevent you from purchasing unnecessary parts. -Matt

Hello Teresa Ann - Typically error code UO indicates that while the dishwasher is in wash cycle, the main control board is not receiving signal from the vent assembly and that the vent plunger is in a closed position. A professional will need to check the wiring between both parts and depending from the results either part may need replacing.
