Amana Washer Error Code F8E3: Overflow/Overfill... | appliancefaults.com

Technical Background:

The MCU monitors the water level pressure switch/sensor to determine the water level in the tub. When the MCU detects a water level exceeding the maximum allowable limit, it triggers the F8E3 error. The MCU controls the water inlet valve via a 120V AC signal, and it processes the signal coming from the water level sensor, usually a 5V DC signal.

Symptoms:

The homeowner observes the washer tub overfilling with water, even when the washer is not in use or after the fill cycle should have ended. Water may be leaking from the washer. The F8E3 error code is displayed on the control panel.

Possible Causes:

Clogged drain hose or drain pump
Faulty water inlet valve sticking open
Defective water level pressure switch/sensor
Damaged or kinked pressure sensor hose
MCU (Main Control Unit) failure
Excessive suds preventing accurate level sensing

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Inspect the drain hose for kinks or clogs. Disconnect the hose and flush it out.
3

Check the drain pump filter for debris. Clean as needed.
4

Verify the water inlet valve closes completely when power is removed. If it continues to drip, replace it.
5

Disconnect the pressure sensor hose from the tub and the pressure switch. Check for cracks, kinks or obstructions. Blow through the hose to ensure it’s clear.
6

Use a multimeter to test the water level pressure switch/sensor. Refer to the service manual for the correct resistance values. Replace if defective.
7

If all other components check out, the MCU may be faulty and require replacement or licensed technician repair.

Safety Warning:

Disconnect power to the washer before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. Some components carry 120V AC which can cause serious injury or death.

Prevention:

Use the correct amount of HE (High Efficiency) detergent. Regularly clean the drain pump filter (every 3 months). Inspect the drain hose for kinks or damage annually.

Expert Tip:

Enter the service mode by pressing and holding the Start/Pause and Option buttons for 3 seconds. Navigate to the error code history to see if other error codes are present, which can help narrow down the root cause of the problem. This may require the service manual for your specific model.

The drain pump filter is typically located behind a small access panel at the bottom front of the washer. You may need a flat-head screwdriver to open the panel. Refer to your owner's manual for specific instructions.

•What is the correct resistance value for the water level pressure switch on my model?

The correct resistance value varies depending on the water level and the specific model. You will need to consult the service manual for your exact Amana washer model to obtain the correct resistance values. Search online using your model number and 'service manual'

•How do I replace the water inlet valve on my Amana washer?

First, disconnect the power and water supply to the washer. Locate the water inlet valve, typically at the back of the washer. Disconnect the hoses and electrical connectors. Remove the valve mounting screws or clips. Install the new valve in the reverse order. Ensure all connections are secure.
