Frigidaire Gallery Dishwasher: iF0 Error Code and 3... | appliancefaults.com

Technical Background:

The iF0 error code indicates a problem with the water inlet system. The main control unit (MCU) monitors the water flow using a flow meter. If the MCU detects insufficient water flow, or no flow at all, it will trigger the iF0 error. Voltage is supplied from the MCU to the inlet valve, typically 120V AC, and the flow meter sends a pulsed signal back to the MCU.

Symptoms:

The Frigidaire Gallery dishwasher stops mid-cycle and beeps three times, displaying the iF0 error code. The dishwasher may not fill with water, or the water level may be incorrect.

Possible Causes:

Blocked water inlet valve screen
Faulty water inlet valve
Defective flow meter
Low water pressure to the dishwasher (less than 20 PSI)
Issue with the main control board (MCU)
Wiring harness damage between the flow meter and the control board

Solution:

1

Turn off the dishwasher and disconnect power at the breaker panel.
2

Inspect the water inlet valve screen for debris. Clean or replace as needed.
3

Verify water pressure to the dishwasher. Should be at least 20 PSI. Use a pressure gauge connected to the water supply line.
4

Use a multimeter to test the water inlet valve solenoid for continuity. A reading of around 1k to 3k ohms is typical. An open circuit indicates a faulty valve.
5

Disconnect and inspect the flow meter wiring harness. Look for corrosion or damage.
6

Check the flow meter signal to the control board using a multimeter in AC voltage mode while running a test cycle. Refer to the wiring diagram for test points. Should read ~2-5V AC.
7

If all other components test good, the main control board may be faulty. Replace the control board.

Safety Warning:

Always disconnect power to the dishwasher at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental re-energizing of the circuit. The water inlet valve operates on 120V AC; exercise caution to avoid electric shock.

Prevention:

Periodically check and clean the water inlet valve screen. Ensure adequate water pressure to the dishwasher. Use a water softener if you have hard water to prevent mineral buildup.

Expert Tip:

Some Frigidaire dishwashers have a service mode. Press and hold the Start/Cancel button for 5 seconds, then press the Up arrow key three times followed by the Start/Cancel button again. This will initiate a diagnostic cycle that can provide more specific error information.

Frequently Asked Questions

•How do I access the water inlet valve on my Frigidaire Gallery dishwasher?

The water inlet valve is typically located behind the lower access panel on the left side of the dishwasher. You will need to remove the access panel using a 1/4-inch nut driver to gain access.

•What is the correct water pressure for a Frigidaire Gallery dishwasher?

The water pressure should be between 20 and 120 PSI. Low water pressure (below 20 PSI) can cause filling problems and trigger error codes.

•How do I test the flow meter on my Frigidaire Gallery dishwasher?

Disconnect the flow meter wiring harness from the main control board. While the dishwasher is running a fill cycle, use a multimeter set to AC voltage to measure the voltage across the flow meter terminals. Consult the wiring diagram to identify the correct test points. A fluctuating voltage reading indicates that the flow meter is functioning.
