Frigidaire Dishwasher Error Codes — Complete List

Frigidaire dishwashers mix two kinds of display message: numbered i-codes — i10, i20, i40 — whose number family maps to a subsystem like filling, draining, or the sump, and short letter codes such as CL, PF, Hd, and LOC that report door, power, heating, and control-lock status. The guides below are verified against Frigidaire's own support documentation, each with ranked causes and the checks that are safe to do yourself.

• i10 Water isn't reaching the tub fast enough — the under-sink valve, a kinked line, or a stuck float explain most i10 errors before any part needs replacing.
• 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.
• i30 Water collected in the pan beneath the tub and the anti-leak response took over — the cause ranges from a one-off overflow or suds episode to a genuine seal failure.
• i60 The water isn't heating the way the cycle requires — the element, its relay, or the temperature sensor is at fault, and all of them are mains-voltage parts for a professional.
• 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.
• i50 The control board has flagged a problem driving the wash motor — the circulation pump that powers the spray arms — and because that's a mains-voltage motor sealed under the tub, it's a repair for a technician.
• iC0 (iCO) The dishwasher's control boards have lost reliable communication — the keypad/display board and the main board aren't exchanging signals — which a power reset sometimes clears but otherwise needs a technician.

Don't see your code?

Older Frigidaire models used different letter-style codes, and Gallery-series units occasionally add variants. If your display shows something not listed here, your model's manual — searchable by the number on the door edge or tub rim — settles it.
