Frigidaire Dishwasher iF0 — Water inlet flow fault

Frigidaire Dishwasher · Error code iF0

What iF0 Means

The dishwasher is not filling with the expected amount of water in the expected time. Either the supply is restricted, the inlet valve is failing, or the flow meter/turbidity sensor is misreading.

Symptoms

  • 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

Common Causes

1
Closed or partially closed water supply valve

Household shutoff under the sink not fully open.

2
Clogged inlet screen at the fill valve

Sediment and scale plug the fine mesh screen on the valve inlet.

3
Failed water inlet valve

Solenoid coil open or stuck closed; valve won't open on command.

4
Faulty flow meter

Flow meter on the fill line stopped pulsing so the board thinks no water is flowing.

5
Low household water pressure

Below ~20 psi the valve flow rate falls under the expected threshold.

How to Fix It

  1. Confirm the under-sink shutoff is fully open and the supply hose isn't kinked.
  2. Close the supply, disconnect the fill hose at the dishwasher, and clean the inlet screen.
  3. Run water from the supply line into a bucket to verify pressure and flow.
  4. Measure inlet valve solenoid resistance (typically ~500-1500 ohms; open = bad).
  5. Replace the water inlet valve if open or stuck.
  6. Inspect the flow meter for debris and verify the wiring harness is seated.
  7. Replace the flow meter if water is flowing but the meter doesn't register.
