What iF0 means on your Frigidaire dishwasher (frigidaire if0 error)
A frigidaire if0 error is grouped by Frigidaire with i20 and i40 as the same drain-line-restricted or filters-clogged condition on your Frigidaire dishwasher. Clean the filters and clear the drain line, and check the inlet supply as well. Standing water is the typical symptom.

Symptoms
Compare what your Frigidaire dishwasher is actually doing against the list below before you settle on a cause, because more than one fault can present this way. On the dishwasher the signs can turn up alone or in a group, sometimes creeping in gradually and sometimes the moment after an outage, a heavy cycle, or a fresh install.
- Standing water in the bottom of the tub
- Dishes are still wet at the end
- A long cycle that does not finish
- Slow draining between fills
Common causes
What you are seeing on your Frigidaire dishwasher can trace back to more than one root cause, which is why the list starts with the most probable. Taking them in turn shows whether your dishwasher needs nothing more than a simple check or a proper repair with genuine Frigidaire parts.
- Clogged filter or glass trap — debris blocks the filter assembly
- Debris in the sump — food restricts the pump intake
- Kinked or clogged drain hose — the hose run is restricted
- Restricted inlet supply — low fill paired with a slow drain
Troubleshooting steps you can try
Handle these checks on your Frigidaire dishwasher in order, easiest first, before you decide you need help. Break off at once if a step on the dishwasher exposes you to live wiring, gas, a hot oven, standing water, or a sealed system, and leave it to a professional.
- Twist out and rinse the filter assembly and clear the sump.
- Inspect the drain hose for kinks and the air gap for blockage.
- Confirm the supply valve is fully open and the inlet screen is clean.
- Press START/CANCEL to drain; if water remains the drain pump needs testing.
Parts a technician may replace
For this condition on a Frigidaire dishwasher, the components a technician may inspect, test, or replace are the filter, glass trap, sump, drain hose, inlet supply, and drain pump. The correct item for your dishwasher is matched from the model and serial number, and genuine OEM parts are supplied through trusted parts suppliers rather than generic substitutes, so performance, safety, and the working life of the dishwasher are all preserved. Proving which part failed before it is ordered means nothing extra is fitted to your dishwasher.
When to call a technician
iF0 that stays after the filters, drain line, and supply are clear needs a technician to test the drain pump.
