Whirlpool Dishwasher F8 E1 Error Code: Sump Cleaning... | appliancefaults.com

Technical Background:

The F8 E1 error code indicates a problem with the turbidity sensor, which measures the cleanliness of the water. The Main Control Unit (MCU) monitors the voltage signal from the sensor. A faulty sensor, obstruction, or wiring issue can cause the MCU to register an incorrect reading, triggering the error. The turbidity sensor typically operates on a 5V DC signal.

Symptoms:

The dishwasher displays an F8 E1 error code, and the wash cycle may not complete properly. Dishes may not be cleaned effectively.

Possible Causes:

Clogged sump filter
Debris obstructing the turbidity sensor
Faulty turbidity sensor
Wiring harness issue to the sensor
Defective dishwasher control board

Solution:

1

Disconnect power to the dishwasher at the breaker panel.
2

Open the dishwasher and remove the lower rack.
3

Remove the sump cover (usually requires a T-20 Torx driver).
4

Inspect and clean the sump area, removing any food particles or debris. Pay close attention to the turbidity sensor.
5

Check the wiring harness and connector to the turbidity sensor for damage or loose connections.
6

Use a multimeter to test the turbidity sensor for proper resistance (refer to the service manual for specifications). Replace if out of spec.
7

Reassemble the dishwasher and restore power. Run a test cycle.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before attempting any repairs. Lock Out / Tag Out (LOTO) procedures should be followed. Dishwashers operate on 120V AC, which can cause serious injury or death.

Prevention:

Regularly clean the dishwasher filter and sump area to prevent debris buildup. Avoid overloading the dishwasher with food residue.

Expert Tip:

To enter service mode on some Whirlpool dishwashers, press and hold the 'High Temp Wash' and 'Heated Dry' buttons simultaneously for 3 seconds. This allows for advanced diagnostics and calibration.

Follow-up Questions:

Question 1: How do I locate the turbidity sensor in my dishwasher?

Answer: The turbidity sensor is typically located in the sump area, near the pump. It's a small, cylindrical sensor with a wiring harness connected to it. Refer to the dishwasher's parts diagram for the exact location.

Question 2: What is the typical resistance range I should expect from a functioning turbidity sensor?

Answer: The resistance range varies depending on the model. Consult the service manual for the specific resistance value for your dishwasher. A typical range might be between 10k and 20k ohms, but always verify with the correct documentation.

Question 3: If cleaning the sump and replacing the turbidity sensor doesn't fix the F8 E1 error, what should I do next?

Answer: If cleaning and sensor replacement doesn't resolve the issue, the problem likely lies with the wiring harness or the control board. Check the wiring harness for continuity and shorts. If the wiring is good, the control board may need to be replaced or reprogrammed by a qualified technician.
