Customer Questions and Answers for Dishwasher Vent Blower Assembly by Frigidaire

Don, The vent motor assembly 5304523304 is located in the right rear top corner of the dishwasher tub assembly, so you'll need to remove the dishwasher from the cabinet. " Drying System The Drying system consists of a Fan/Vent assembly, Heater, and Air Baffles. The way the systems performs is; as the dry portion of a wash cycle is reached the control activates the heater, if selected, and opens the vent door, located in the top right rear of tub, this allows the vent fan to draw in outside air resulting in hot air being forced out the bottom of the outer door panel." The codes you supplied indicate two issues for your dishwasher: "Er"-Membrane Switch failure- When the control verifies that any of the pads on the membrane switch has been closed for one minute the failure will appear in the display. "uo"- Vent open - When in a wash cycle the control does not receive the proper indication that the vent is closed. The control will try to reseat the vent if after 5 attempts the vent does not close the failure will appear. The cycle will not start. Both repairs can be performed by the basic "do it yourselfer", with basic hand tools and a little time.
