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

Technical Background:

The MCU monitors the water level using a pressure sensor (or switch) connected to the tub via an air dome and hose. The MCU controls the water inlet valve and drain pump based on the pressure sensor readings. An F8E3 error indicates that the MCU has detected an overfill condition.

Symptoms:

The washer fills with too much water, overflows, or displays the F8E3 error code during or after filling. The washer may also fail to drain completely.

Possible Causes:

Faulty pressure sensor/switch
Clogged drain hose or drain pump filter
Defective water inlet valve
Damaged or blocked air dome/pressure hose
Malfunctioning main control unit (MCU)

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Inspect the drain hose for kinks or obstructions. Clean the drain pump filter (usually located behind a small access panel at the bottom front of the washer) of any debris.
3

Check the air dome/pressure hose for kinks, cracks, or clogs. This hose runs from the bottom of the tub to the pressure switch.
4

Using a multimeter, test the water inlet valve solenoid for continuity. A reading of around 1k-2k ohms is typical. Replace if open or shorted.
5

Disconnect the pressure switch connector and use a multimeter to check for continuity with the tub empty and full. Compare readings to the service manual.
6

If the pressure switch and inlet valve test good, and the plumbing is clear, suspect a faulty MCU. Replacement may be necessary. Requires licensed technician assistance.
7

After repairs, run a calibration cycle (if available) per the service manual.

Safety Warning:

Disconnect power before servicing. Capacitors in the control board can hold a charge even after the unit is unplugged. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization during repair.

Prevention:

Periodically clean the drain pump filter (every 3-6 months). Use the correct type and amount of detergent. Inspect the drain hose for kinks or damage.

Expert Tip:

Some Admiral washers have a diagnostic mode. Consult the service manual for the specific key sequence to enter service mode. You can often run individual component tests (e.g., inlet valve, drain pump) from within the diagnostic mode to isolate the problem.

Frequently Asked Questions

•What is the resistance reading I should expect from the pressure switch when the tub is empty?

The resistance value will vary by model. Consult the service manual for your specific Admiral washer model. Typically, it will be a closed or open circuit. The manual will have the correct ohm value.

•Where is the air dome located on my Admiral washer?

The air dome is usually located at the bottom of the outer tub, often near the drain pump. It's a small, enclosed chamber connected to the pressure hose. The hose runs from the air dome up to the pressure switch, which is usually mounted on the top panel or near the control board.

•How do I recalibrate the water level sensor after replacing the MCU?

The recalibration procedure varies significantly by model. It almost always requires entering a service mode (test mode) by pressing certain buttons on the control panel in a specific sequence. You absolutely need the service manual for your specific model to perform this procedure correctly.
