iF0 — Undocumented (Likely Restricted Flow)
iF0 is not listed in Frigidaire’s official dishwasher error-code guide (which documents i20 = incomplete drain and i40 = clogged filter/sump). Third-party sources associate it with a clogged filter / restricted water flow rather than a fill-quantity fault. Verify against your model’s service documentation; start by cleaning the filter and checking the sump/water path.

How to fix it
- Confirm the under-sink shutoff is fully open and the supply hose isn't kinked.
- Close the supply, disconnect the fill hose at the dishwasher, and clean the inlet screen.
- Run water from the supply line into a bucket to verify pressure and flow.
- Measure inlet valve solenoid resistance (typically ~500-1500 ohms; open = bad).
- Replace the water inlet valve if open or stuck.
- Inspect the flow meter for debris and verify the wiring harness is seated.
- Replace the flow meter if water is flowing but the meter doesn't register.
Why it happens
Typical signs: Cycle stalls early and shows iF0 · Little or no water entering the tub · Wash pump runs dry briefly then shuts off · Long fill times before fault
- Closed or partially closed water supply valve Household shutoff under the sink not fully open.
- Clogged inlet screen at the fill valve Sediment and scale plug the fine mesh screen on the valve inlet.
- Failed water inlet valve Solenoid coil open or stuck closed; valve won't open on command.
- Faulty flow meter Flow meter on the fill line stopped pulsing so the board thinks no water is flowing.
- Low household water pressure Below ~20 psi the valve flow rate falls under the expected threshold.
