Frigidaire Dishwasher Error Code iF0: Water Intake... | appliancefaults.com

Technical Background:

The iF0 error indicates the dishwasher's Main Control Unit (MCU) isn't sensing the proper water level within a specific timeframe (water intake timeout). The MCU applies 120V AC to the water inlet valve solenoid. A flow meter, if present, sends feedback to the MCU. The MCU monitors this feedback. If the expected water level isn't reached within the programmed time, the iF0 error is triggered.

Symptoms:

The dishwasher starts, but doesn't fill with water, or fills very slowly. The iF0 error code appears on the display. You may also hear humming from the water inlet valve, even though no water is entering.

Possible Causes:

Blocked water inlet valve screen
Faulty water inlet valve
Low water pressure to the dishwasher
Clogged drain hose or air gap (causing siphoning)
Defective flow meter (if equipped)
Malfunctioning control board

Solution:

1

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

Check the water supply line for kinks or obstructions. Ensure the shut-off valve is fully open.
3

Inspect the water inlet valve screen for debris. Clean or replace as needed.
4

Using a multimeter, test the water inlet valve solenoid for continuity. A reading of approximately 500-1500 ohms is typical. If open or shorted, replace the valve.
5

Verify water pressure to the dishwasher is at least 20 PSI. A garden hose pressure gauge can be used.
6

Inspect the drain hose for clogs and ensure the air gap (if present) is clean and functioning correctly.
7

If all else fails, the control board may be defective and require replacement. Consult a qualified technician.

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. 120V AC is present in the dishwasher; exercise caution.

Prevention:

Periodically clean the water inlet valve screen. Check the drain hose and air gap for blockages every 6 months. Ensure adequate water pressure to the home.

Expert Tip:

On some Frigidaire models, entering service mode involves pressing and holding the 'Start/Cancel' button for 5 seconds. This allows you to run diagnostic cycles and manually activate components like the water inlet valve for testing.

Frequently Asked Questions

•Where is the water inlet valve located?

The water inlet valve is usually located at the bottom rear of the dishwasher, behind the lower access panel. You'll need a 1/4-inch nut driver to remove the panel.

•How do I test the water pressure?

You can use a garden hose pressure gauge, available at most hardware stores. Attach it to the water supply line after disconnecting it from the dishwasher. Open the shut-off valve fully to get a pressure reading.

•What is the typical cost to replace the control board?

Control board replacement can range from $200 to $400, including parts and labor. It's best to get a quote from a local appliance repair technician.
