Covers: Frigidaire FDPC4314A* built-in front-control dishwashers: AS stainless, AB black, AW white (ENERGY STAR lists the family as FDPC4314****). Built in Kinston, NC; sold from about 2021 as a builder/rental staple.

Cross-checkedBrands: Frigidaire8 components

An entry-level Frigidaire with a plastic tall tub, 14 place settings (ENERGY STAR lists 12), 54 dBA, four cycles, five wash levels with three Bi-Beam style arms, a removable filter, a soil sensor and static-vent drying (no fan). Most calls are drain (i20), leaks and poor drying, which is often expected behavior on a plastic-tub, non-fan unit.

Safety first

Breaker off before removing the kick plate; hard-wired units can be live at the junction box.
Close the hot-water valve before touching the inlet valve.
Let the element cool after a cycle.
Never bypass the float switch.

How it works

Fill through the inlet valve (bottom left front) to the level limited by the float; a single-speed wash motor circulates water through lower, middle and upper spray paths.

A removable filter in the tub floor traps soil and must be cleaned by the owner; it is not self-cleaning.

A smart soil sensor and automatic temperature control adjust the Normal cycle; the element heats water and drying air. Drying is static vent (heat and residual moisture, no fan), so plastics stay damp.

Error i20 means the unit did not drain properly (Frigidaire support).

Diagnostic guides for this appliance

Guide · Dishwasher

Dishwasher detergent dispenser won't open (detergent left in the cup)

First rule out blocking dishes, caked detergent and an unfinished cycle. Then test the dispenser actuator (a wax motor or bimetal/solenoid on most units) for an open circuit, and check whether the control sends 120 V to it during the wash. A cup that opens but leaves detergent behind is a wash problem, not a dispenser problem.

Guide · Dishwasher

Gritty or sandy residue on dishes after washing

Grit is usually redeposited soil: a clogged filter, a drain that cannot clear (air gap, disposer, hose) or detergent that did not dissolve. Hard water causes white film rather than grit. Work from the filter outward, then check the drain path and the wash motor.

Dishwasher completely dead: no lights, no response (supply, door switch, thermal fuse)

Prove supply voltage at the junction box with a meter before blaming any part. Then check the door switch circuit and, on units that have one, the one-time thermal fuse near the control. Replace the control board only after these pass.
