Whirlpool Load & Go™: Fixing Empty Tray Error & Sensor... | appliancefaults.com

Technical Background:

The Load & Go system uses a sensor to detect the detergent level in the reservoir. The sensor sends a voltage signal to the Main Control Unit (MCU). The MCU interprets this signal and displays the appropriate message on the control panel. Faulty sensors or wiring can disrupt this voltage path, leading to an incorrect error message.

Symptoms:

The Whirlpool Load & Go washer displays an "Empty Tray" error message even when the detergent reservoir is full. The automatic detergent dispensing system may not be functioning correctly.

Possible Causes:

Faulty Load & Go Detergent Level Sensor
Damaged wiring harness to the sensor
Corroded or loose electrical connections
Software Glitch in the Main Control Unit (MCU)
Low voltage supply to the sensor circuit
Blocked or contaminated detergent reservoir affecting sensor readings

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Locate the Load & Go detergent reservoir and sensor. This is typically on the dispenser drawer assembly.
3

Inspect the wiring harness connected to the sensor for any visible damage, cuts, or loose connections. Use a 1/4-inch nut driver to remove any access panels.
4

Use a multimeter to check the voltage supply to the sensor. Refer to the washer's wiring diagram for the correct voltage (usually 5V DC). Set the multimeter to DC volts and test across the sensor's power and ground pins.
5

Check the sensor resistance with a multimeter. A reading outside the specified range (refer to the service manual) indicates a faulty sensor. Set the multimeter to Ohms and test across the sensor's signal pins.
6

If the wiring and sensor appear good, try power cycling the washer by unplugging it for 5 minutes to reset the MCU.
7

As a last resort, consider replacing the Main Control Unit (MCU) if all other components test good. Note: this requires licensed technician service and programming in some cases.

Safety Warning:

Disconnect power to the washer at the breaker panel before performing any troubleshooting or repairs. Always observe Lock-Out/Tag-Out (LOTO) procedures. High voltage is present in the control panel and wiring.

Prevention:

Regularly clean the detergent reservoir to prevent buildup and clogs. Use only HE (High Efficiency) detergent as recommended by Whirlpool. Avoid overfilling the reservoir.

Expert Tip:

Some Whirlpool washers have a diagnostic mode that allows you to test the Load & Go sensor. Consult the service manual for instructions on entering and using the diagnostic mode. This can help pinpoint the problem.

Frequently Asked Questions

•Where can I find the wiring diagram for my Whirlpool Load & Go washer?

The wiring diagram is usually located inside the washer's control panel or on the back panel. You can also find it in the service manual for your specific model.

•What is the correct resistance range for the Load & Go detergent level sensor?

The resistance range varies depending on the model. Refer to the service manual for your specific washer model to find the correct values. Generally, you are looking for a resistance change based on the level of the detergent.

•How do I access the diagnostic mode on my Whirlpool Load & Go washer?

The diagnostic mode access varies. Usually, it involves pressing a specific sequence of buttons on the control panel within a short time frame. Consult your service manual or search online for the specific sequence for your washer model.
