Whirlpool Washer F8 E3 Error: Overflow and Suds... | appliancefaults.com

Technical Background:

The F8 E3 error indicates an overflow condition. The Main Control Unit (MCU) receives signals from the pressure sensor indicating a water level exceeding the maximum threshold. The MCU logic dictates the activation of the drain pump to evacuate water. Voltage paths to the drain pump and inlet valve are crucial for proper operation. The MCU is 120V AC powered.

Symptoms:

The Whirlpool washer displays an F8 E3 error code and the tub is filled with excessive suds, potentially overflowing.

Possible Causes:

Excessive detergent usage (especially non-HE detergent).
Faulty pressure sensor (measures water level).
Clogged drain line or drain pump.
Defective water inlet valve.
Software glitch in the washer's control board.

Solution:

1

Unplug the washer from the outlet or turn off the breaker at the breaker panel.
2

Check the drain hose for kinks or clogs. Remove the hose and inspect for obstructions.
3

Locate the pressure sensor (usually near the bottom of the tub) and check its connection to the control board. Inspect wiring for damage.
4

Access the drain pump (usually behind an access panel). Clean out any debris. Test the pump for continuity with a multimeter. You should see a resistance reading if the pump motor is good.
5

Check the water inlet valve(s) for proper closure. If one valve is stuck open, it will continuously fill the tub. Use a multimeter to check for 120V AC at the valve when it should be closed.
6

Run a diagnostic cycle to clear the error code. Consult your washer's service manual for the proper procedure. This often involves pressing specific buttons in a sequence.
7

If the problem persists, consider replacing the pressure sensor or the main control board.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental re-energizing of the circuit. High voltage is present within the appliance; exercise caution.

Prevention:

Always use High-Efficiency (HE) detergent and follow the manufacturer's recommended amount. Regularly clean the drain pump filter to prevent clogs. Run a washer cleaning cycle with a washing machine cleaner every few months.

Expert Tip:

Try accessing the service mode (usually a sequence of button presses, consult your service manual) and manually activate the drain pump to fully empty the tub. This can sometimes clear a minor blockage and reset the system.

Frequently Asked Questions

•How do I locate the pressure sensor on my Whirlpool washer?

The pressure sensor is typically located near the bottom of the outer tub, often accessible from the rear or side of the washer. It's usually a small, round plastic component with a hose connected to it.

•What resistance reading should I expect when testing the drain pump with a multimeter?

A typical drain pump resistance reading is between 5 and 20 ohms. An open circuit (infinite resistance) indicates a faulty pump, while a very low resistance (close to zero) may indicate a short circuit.

•Where can I find the service manual for my specific Whirlpool washer model?

You can usually find the service manual online by searching for your washer's model number followed by 'service manual'. Websites like AppliancePartsPros or RepairClinic often have them available for download. You can also contact Whirlpool directly.
