Frigidaire Dishwasher Error Codes — Complete List

Frigidaire dishwashers mix numbered codes with short status messages. i20 means the unit didn't drain completely and i40 that the filter or sump is clogged; CL (or Cd) is a door that isn't latched, PF a loss of power, Hd (or HO) a heating delay, and LOC a locked door.

• i20 The unit didn't drain properly — Frigidaire's filters and glass trap clog like any brand's, and the drain hose and disposal connection make up the rest of the usual story.
• i40 Food soil has built up in the sump and filter to the point water can't circulate freely, and Frigidaire's own remedy is to pull the glass trap and filter and rinse them clean.
• CL (Cd) The control hasn't sensed the door fully shut and latched, so it won't start the cycle — usually a door left a touch ajar, an item poking past the tub, or a strike knocked out of line.
• PF Power to the dishwasher was cut mid-cycle and it's flagging the interruption — a one-off after an outage clears with a button press, while a PF that keeps returning points at the supply.
• Hd (HO) Hd and HO aren't errors at all — they show the dishwasher is pausing to bring the wash or rinse water up to temperature, a normal wait that runs longer the colder your incoming water is.
• LOC LOC means the control lock — the child lock — is switched on, freezing the buttons so the cycle can't be changed or started until you unlock it with the Delay Start pad.
