The short answer
On a Frigidaire dishwasher, a white film on the load most often comes down to a blocked or glazed filter stack. Frigidaire dishwashers keep a check valve in the drain path, and a stuck valve produces standing water that looks exactly like a dead pump. The first check below needs no tools, and the list stops where a meter on live terminals begins.
What you observe
- Dishes come out with food still on them — Particles are being moved around rather than washed away.
- A gritty film on glasses and the tub floor — Debris is recirculating instead of leaving with the drain water.
- The top rack cleans worse than the bottom — A pressure problem rather than a chemistry problem.
- NEAR MISS — dishes are clean but soaking wet — That is a drying complaint and a different page.
Causes, most likely first on a Frigidaire dishwasher
- Blocked or glazed filter stack — Ranked first here: a filtered machine relies on the owner to clean the filter, and most owners do not know it exists.
- Old detergent or the wrong dispenser — Ranked second: detergent loses activity on the shelf, and a blocked dispenser flap releases it at the wrong moment.
- Hard water scaling the machine — Last on this list: scale coats the heater and the jets, and it is mistaken for a failing machine.
Check in this order, and why
- Twist out the filter stack and look at it against the light — A greasy film counts as blocked even when it looks clean. First: likeliest cause, least effort.
- Open the door mid-cycle and see whether the dispenser has released — A full dispenser at the end is the whole answer. Second: it separates the next two causes.
- Look for white scale on the heater and the tub floor — Scale is visible and it is diagnostic. Third: only once the checks above are clean.
What an owner can safely check
- Remove the filter stack and wash it in hot soapy water — Grease glazes a filter that still looks open.
Tools: washing-up brushAbout 15 min
- Wipe the sump recess the filter sits in — Debris collects under the filter as well as in it.
Tools: clothAbout 10 min
- Check the dispenser flap is not blocked by a tall item in the rack — This is the single most common loading mistake.
Tools: noneAbout 5 min
- Open a fresh box of detergent and try one cycle — Detergent degrades once opened, especially powder in a damp kitchen.
Tools: noneAbout 5 min
- STOP HERE if the next step needs a meter on live terminals — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off.
When to call a technician
Call once the filter, the spray arms and the drain path are all proven clear and the fault is unchanged, because the next tests are on live terminals inside a wet cabinet. Call immediately if you see water at the electrical panel, if the cabinet trips the breaker, or if there is standing water under the machine rather than in it.

What this page does not cover
This page covers Frigidaire dishwashers as a class, not one family or model line. It reasons from how Frigidaire builds this appliance — enough to rank the causes, not enough for wiring colours, torque figures or part numbers, which differ by family. Where a model-specific page exists it is linked here and is the better answer; this class page has no such child yet, so nothing is withheld by omission.
