iF2 Serious Moderate DIY
Frigidaire Dishwasher iF2 — Overfill / water level too high
Frigidaire Dishwasher · Error code iF2
What iF2 Means
The pressure or flow sensing system detects more water in the tub than expected. The drain pump runs to protect against overflow.
Symptoms
- Drain pump runs continuously
- iF2 displayed, cycle won't continue
- Water level visible above the heater
- Possible leak underneath if overfill persists
Common Causes
1
Water inlet valve stuck open
Diaphragm or solenoid stuck — water keeps entering even with power removed.
2
Failed pressure switch / level sensor
Sensor reports overfill incorrectly.
3
Clogged pressure hose to the switch
Air column gets stuck and gives a high reading.
4
Drain pump not pumping fast enough
Partial blockage in drain hose lets water rise during fill.
How to Fix It
- Shut off the household water supply immediately.
- Power-cycle the dishwasher and bail water from the tub.
- Confirm the inlet valve is fully closing — listen for water still trickling in with power off.
- Inspect the pressure switch hose for debris or kinks; clear it.
- Test the drain pump and hose for restriction up to the air gap or disposer.
- Replace the inlet valve if it leaks through.
- Replace the pressure switch or control board if the sensor is faulty.
