Whirlpool Washer Error Code F8 E3: Water Overflow/Pressur... | appliancefaults.com

Technical Background:

The F8 E3 error indicates a problem with the water level sensing system. The Central Control Unit (CCU) monitors the pressure sensor to determine the water level in the tub. The pressure sensor outputs a voltage that varies with the water level. The CCU interprets this voltage and controls the water inlet valve and drain pump accordingly. An incorrect voltage, or a lack of change in voltage when filling, triggers the F8 E3 error. The pressure sensor typically operates on 5V DC.

Symptoms:

The washer displays an F8 E3 error code on the control panel. The washer may overfill with water, or it may not fill at all. The washer may also stop mid-cycle.

Possible Causes:

Faulty pressure sensor
Clogged or kinked pressure sensor hose
Water inlet valve not closing completely
Drain pump malfunction
Defective Central Control Unit (CCU) / Main Control Board
Over sudsing condition causing false readings

Solution:

1

Unplug the washer from the electrical outlet.
2

Access the pressure sensor and hose. It's typically located near the bottom of the washer, often behind an access panel secured with screws (usually a 1/4-inch nut driver is needed).
3

Inspect the pressure sensor hose for kinks, clogs, or damage. Disconnect the hose from both the sensor and the tub and blow through it to ensure it's clear. Replace the hose if damaged.
4

Check the water inlet valve(s) for proper operation. Ensure they close completely when the washer is off. If leaking, replace. Disconnect the power and use a multimeter to check the coil resistance; a reading outside the expected range (typically around 1k - 2k ohms) indicates a faulty valve.
5

Using a multimeter, check the pressure sensor's output voltage while slowly filling the tub with water. The voltage should change linearly with the water level. A stable reading, regardless of the water level, indicates a faulty sensor. Replace the sensor.
6

Inspect the drain pump for any obstructions. Clean or replace the pump if necessary. Use a 5/16-inch socket to remove mounting screws.
7

As a last resort, if all other components check out, the Central Control Unit (CCU) may be faulty and require replacement. This should be done by a qualified technician. Check for 120V AC at the CCU input.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Electrical shock hazard exists when working with energized circuits. Lock Out / Tag Out (LOTO) procedures should be followed by qualified technicians when repairing appliances. Capacitors can store a charge even after disconnection. High voltage is present in the appliance control circuits.

Prevention:

Use the correct amount of HE (High Efficiency) detergent. Avoid overloading the washer. Regularly clean the washer tub and dispenser to prevent buildup that can cause clogs.

Expert Tip:

Some Whirlpool washers have a diagnostic mode. To access it, rapidly press a specific sequence of buttons (often three buttons in a row). Consult the service manual for the specific sequence for your model. Within the diagnostic mode, you can often run a calibration cycle for the pressure sensor, which might resolve the F8 E3 error.

Frequently Asked Questions

•Where is the pressure sensor located on my Whirlpool washer specifically?

The pressure sensor is typically located at the bottom of the washer cabinet, often near the base or the side. You'll usually need to remove an access panel (secured by screws or clips) to reach it. The exact location varies slightly by model, so consult your washer's service manual for the most accurate location.

•What is the correct resistance range for the pressure sensor on my Whirlpool washer?

The resistance range for the pressure sensor varies depending on the water level and the specific model of your washer. A typical pressure sensor might read between 1k and 5k ohms. Refer to the washer's service manual or technical sheet for the exact resistance values at different water levels.

•How do I reset the F8 E3 error code after fixing the problem?

The F8 E3 error code should automatically clear once the underlying problem is resolved. If the error code persists, try unplugging the washer from the electrical outlet for 5 minutes to reset the control board. Some models may require entering the diagnostic mode and clearing the error codes manually. Consult the service manual for your model for the specific procedure.
