Frigidaire / Electrolux dishwasher: field service manual

Covers: Frigidaire and Electrolux 24 in built-in dishwashers (FFID, FGID, FDB, FGBD, FPID families and Electrolux-branded units). Electronic models show i-codes; older mechanical/LED units use flashes or beeps.

Cross-checkedBrands: Frigidaire, Frigidaire Gallery, Frigidaire Professional, Electrolux11 components

A straightforward design: a circulation (wash) motor/pump assembly on a sump, a separate drain pump with a check ball, a heating element in the bottom of the tub, a turbidity sensor on many electronic models and a float/flood switch. The supply has an integral air gap meeting ASSE 1006. Common calls are i20 (drain), i30 (leak), i10 (fill) and i60 (heat).

Safety first

  • Breaker off before opening the toe kick or door.
  • Water off before the inlet valve.
  • Glass in the sump.

How it works

Fill: the inlet valve fills to level; i10 means level too low, usually a supply problem. Frigidaire asks for a hot line at 20-120 psi and at least 120 °F.

Wash: the wash motor drives the pump to the arms. If the drain pump runs but the wash motor does nothing, there is no circulation in wash or rinse.

Heating: the element in the bottom of the tub heats water during wash and dry; i60 flags a heating fault. A heater relay on the control can fail (including a cold solder joint) while the element tests good.

Soil sensing: many electronic models use a turbidity sensor; a 'tu' code points to that sensor or its wiring.

Drain: the drain pump empties the tub through a check ball/valve; if the ball does not seat, drain water flows back after the cycle. i20 = drain restriction.

Flood protection: water in the base pan sets i30; meanings of i40/iF0 vary by source (drain/filter restriction vs flood).

How to test a dishwasher heating element

Many US dishwashers have a hidden or visible loop element under the tub. A good one reads in the tens of ohms. A leak to the tub trips the GFCI even when the resistance looks fine, so always check to ground.

How to test a dishwasher circulation (wash) pump motor

The wash motor pushes water to the spray arms. Older units use an AC induction motor; many newer ones use a brushless DC motor driven by the board. Rule out a jam and a filter clog before testing, and use the tech sheet for winding values.

How to test a float switch (dishwasher overfill and similar)

A float rides up with water and opens or closes a small switch under the tub. It stops overfill or flags a leak. Make sure the float moves freely before blaming the switch.
