What UF (uF) means

On Frigidaire Professional fully integrated direct-feed dishwashers, such as PLD4555RFC0 and PLD4375RFC0, uF means the fan is not running. In dry mode the control expects feedback from the vent that the fan is turning at the right speed. When it does not get that feedback, the failure appears and the control shuts the cycle down. You will see uF on the display and the dishes may be wet at the end. These are older dishwashers still in many homes, and we repair them.

Common causes of UF (uF)

  • The vent fan motor and its connection
  • The vent assembly and anything that blocks its movement
  • The feedback wiring from the vent to the control
  • The control that reads the feedback
✓ One safe check you can try

1. Cancel the cycle and let the dishwasher rest for a few minutes. 2. Check that nothing blocks the vent opening on the door or tub. 3. Run a short cycle that finishes with the dry mode. 4. If uF returns, stop using the drying step and call us to schedule service.

! Why to stop there
  • The dishwasher may wash fine and only stop at the drying stage, so your checks cannot show whether the fan or the feedback is the problem.
  • We test the fan, the vent movement and the wiring in that order.
  • We tell you plainly if the repair is not worth it on a dishwasher this age.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

UF (uF)UF (uF) questions
Why do my dishes come out wet with uF showing?

The control shuts the cycle down when it does not see the vent fan turning at the right speed, so drying may not finish. We find out whether the fan, the vent or the feedback is the problem. The vent and fan work together, so we check both before deciding on a part.

Can I keep washing and dry the dishes by hand?

You may be able to, but we recommend not repeating the cycle until it is checked. The control stops the cycle on purpose. It is also worth knowing the dishwasher is stopping on purpose, as a protection, rather than failing at random.

Do you repair this older model?

Yes. We repair Frigidaire Professional direct-feed dishwashers and give you the written price before any work. The visit includes a written price first. Bring the dishes out and dry them by hand if you must, and tell us what the display showed.
