Frigidaire Dishwasher Error Code uF

The uF code means the control board did not receive proper feedback from the vent fan motor during the drying cycle. The board monitors fan speed to confirm the fan is running correctly, and when that confirmation signal is missing or incorrect, the control shuts the drying operation down. This protects the appliance and alerts you to a problem with the vent fan system.

The uF fault causes the control to shut down the drying cycle, so the dishwasher may still complete the wash portion of the cycle. However, continuing to run the appliance without addressing the fault means your dishes will not dry properly, and the underlying fan issue could worsen over time. It is best to diagnose and resolve the fault before regular use continues.

Repair costs depend on which component has failed. Wiring repairs or clearing an obstruction may cost little to nothing beyond your time. A replacement vent fan motor typically runs in the range of $30 to $80 for parts, while a control board replacement can range from $100 to $250 or more for parts alone. Adding professional labor generally increases the total cost by $75 to $150 depending on your area.

Some causes of the uF error are DIY-friendly. You can start by checking for obstructions in the vent and fan area, inspecting wiring connections for looseness or corrosion, and confirming the fan blade spins freely. If the motor has failed or the control board is defective, those repairs typically require replacing components and may be better handled by a technician if you are not comfortable working with appliance wiring.

A reset may temporarily clear the uF code, but it will return as soon as the dishwasher runs through a drying cycle again if the underlying fault has not been corrected. Resetting is useful for confirming whether the error is persistent, but it does not fix the fan, wiring, or vent issue causing the code.
