Frigidaire Dishwasher Error Code i10: How to Fix It

Human Verdict

I see this often on new installs or after maintenance. In one case, I triggered an i10 code simply because I forgot to turn the water supply valve back on after installing the unit. Before you start tearing things apart, verify your water supply is fully open and the line isn’t kinked. Use the diagnostic mode to run the fill valve test and confirm water is actually entering the tub.

What It Means

The i10 error code indicates a low water level or a no water condition. The dishwasher has detected that it is not filling with water within the expected time frame.

Common Causes

• Water Supply Issues: A blocked water supply line, a partially closed water shutoff valve, or a kinked hose.
• Faulty Water Inlet Valve: The valve that opens to let water in may be failed or clogged.
• Clogged Inlet Screen: Debris in the mesh screen of the water valve can restrict flow.
• Malfunctioning Float Switch: If the float is stuck in the “up” position, the machine thinks it’s full and won’t let water in.

Step-by-Step Fix

1. Check the Water Supply

Before entering diagnostics, ensure your home’s water supply valve to the dishwasher is fully open. Check the supply line for any kinks that might be restricting flow.

2. Enter Diagnostic Mode

To troubleshoot effectively, you can enter the dishwasher’s diagnostic mode:

1. With the unit powered on and the display active, locate the 1st and 3rd buttons on the keypad.
2. Press and hold both buttons simultaneously for about 5 seconds.
3. The lights on the display should start flashing, indicating you are in diagnostic mode.

3. Check Stored Error Codes

Once in diagnostic mode:

1. Press the 1st button once.
2. The display will show the most recent error code (e.g., i10).
3. Pressing it again will show the second and third stored codes.

4. Run the Fill Valve Test (Test 6)

You can force the dishwasher to fill to verify if the valve is working:

1. While in diagnostic mode, press the 1st button repeatedly until you reach Test 6.
2. Close the dishwasher door.
3. The fill valve should energize, and you should hear water entering the tub.
4. If you hear a hum but no water enters, and the supply is on, the valve or screen is likely clogged or failed.

5. Clear Error Codes

After fixing the issue:

1. Enter diagnostic mode again (hold 1st and 3rd buttons).
2. Press the 2nd button. This will illuminate all lights and clear the stored error codes.
3. Press Cancel to return to normal operation.
