Whirlpool WDT750SAKZ Dishwasher F8 E1 Error: Water... | appliancefaults.com

Technical Background:

The F8 E1 error indicates that the dishwasher's control unit (CCU) is not detecting sufficient water flow within a specified time. The CCU monitors the flow meter signal. If the expected signal is not received within the predetermined timeframe after the water inlet valve is energized, the F8 E1 error is triggered. Voltage paths are 120V AC to the water inlet valve, signal from flow meter to CCU.

Symptoms:

The dishwasher displays an F8 E1 error code and does not fill with water. Dishes are not cleaned properly. The wash cycle may stop prematurely.

Possible Causes:

Clogged or kinked water inlet hose.
Defective water inlet valve.
Low water pressure to the dishwasher.
Faulty flow meter.
Problem with the Central Control Unit (CCU) preventing water fill.

Solution:

1

Turn off the dishwasher and disconnect power at the breaker panel.
2

Check the water supply hose for kinks or obstructions. Straighten any kinks or remove any blockages.
3

Verify water pressure to the dishwasher using a water pressure gauge. It should be between 20-120 PSI.
4

Locate the water inlet valve (usually at the bottom rear of the dishwasher). Disconnect the wires to the valve and test for continuity with a multimeter. If no continuity, replace the valve.
5

Inspect the flow meter. Check the wiring harness and connector to the flow meter for damage or corrosion. Use a multimeter to test for continuity. Replace if necessary.
6

If the water inlet valve and flow meter are functioning properly, the CCU may be faulty. Replacement of the CCU requires programming by a qualified technician.

Safety Warning:

Always disconnect power to the dishwasher at the breaker panel before performing any repairs. Lock Out Tag Out (LOTO) procedures should be followed. The dishwasher operates with 120V AC, which can cause electrocution.

Prevention:

Periodically check and clean the water inlet valve screen to prevent clogs. Ensure adequate water pressure to the dishwasher.

Expert Tip:

After replacing the water inlet valve, run the diagnostic cycle to clear the error code and ensure proper operation. Press the following sequence within 6 seconds: HEATED DRY, NORMAL, HEATED DRY, NORMAL. The diagnostic cycle will last approximately 23 minutes.
