Whirlpool Washer Error Code F8 E1: Troubleshooting Slow... | appliancefaults.com

Technical Background:

The F8 E1 error code on a Whirlpool washer typically indicates a problem with the water inlet system. The MCU (Main Control Unit) monitors the water level via the pressure sensor/switch. If the water level doesn't reach the expected level within a certain timeframe, the MCU throws the F8 E1 error. Voltage paths to the inlet valves and pressure sensor are critical for proper operation.

Symptoms:

The Whirlpool washing machine displays an F8 E1 error code. The water fills very slowly, or doesn't fill at all. The washer may not start a cycle or may stop mid-cycle.

Possible Causes:

Clogged inlet screens on the water inlet valve.
Low water pressure to the washing machine.
Faulty water inlet valve (hot or cold).
Kinked or damaged water supply hoses.
Defective pressure sensor/switch.
Issue with the main control board (MCU).

Solution:

1

Turn off the power to the washing machine at the breaker panel.
2

Turn off the water supply valves (both hot and cold) to the washing machine.
3

Disconnect the water supply hoses from the back of the washer.
4

Inspect the inlet screens on the water inlet valve for debris. Clean or replace as needed.
5

Check the water pressure to the supply hoses. It should be a minimum of 20 PSI.
6

Using a multimeter, test the water inlet valve coils for continuity. A reading of approximately 1.2k ohms is expected. Replace the valve if open or shorted.
7

Inspect the pressure hose connected to the pressure switch/sensor for kinks, clogs, or damage.
8

If the above steps don't resolve the issue, the main control board (MCU) may be faulty. Replacement may be necessary.

Safety Warning:

Disconnect power to the washing machine at the breaker panel before performing any repairs. Use Lock-Out/Tag-Out (LOTO) procedures. Be aware of high voltage components within the machine. If you're not comfortable working with electricity, consult a qualified appliance repair technician.

Prevention:

Regularly clean the inlet screens on the water inlet valve (every 6 months). Check water supply hoses for kinks or damage annually. Ensure adequate water pressure to the washing machine.

Expert Tip:

To access the diagnostic mode on some Whirlpool washers, press and hold the Start/Pause button for 3 seconds, then press the Power button. This may allow you to run tests and clear error codes.

Frequently Asked Questions

•What is the typical water flow rate I should expect from the supply hoses?

A normal flow rate should fill a 5-gallon bucket in approximately 1 minute.

•How do I test the pressure sensor/switch?

You can test the pressure switch for continuity using a multimeter. Disconnect the hose and blow into the switch. The continuity should change when pressure is applied.

•Where can I find the correct replacement water inlet valve for my specific Whirlpool washer model?

The part number can be found on the valve itself. You can then order it from a reputable appliance parts supplier like RepairClinic or AppliancePartsPros using your model number.
