How do i replace upper vent on a frigidaire dishwasher 4000series aquasurge

Good Afternoon Friend,

I understand your Frigidaire dishwasher, model# PLD3465REC, will not start. I suggest resetting your appliance, by either unplugging it or shutting the power off at your home's circuit breaker, for 20-30 minutes. Restore power and start any cycle. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your appliances status has changed successfully. Hope this is helpful.

-Best Regards-

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.

is drain hole itself clogged?

Try to reset unit to factory defaults. If necessary contact mfg for protocol to accomplish this

You might remove the front panel (screws on the sides) pop off the front plate, and remove the fuse. Put it back in after 5 minutes... sometime this fixes it

I would suspect a faulty touchpad/console. They get moisture in them and short out causing all sorts of problems.

the low light refers to the rince aid being empty. fill it back up and the light will turn off

VO is vent sticking open, in top of tub upper right. You may be able to clean if not replace it.

Mary,

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.

Good Luck
