Kenmore Washer uL Error: Troubleshooting Guide for Small... | appliancefaults.com

Technical Background:

The uL error typically indicates an unbalanced load condition detected by the washer's MCU (Main Control Unit). The MCU monitors signals from sensors, including the pressure switch and motor speed sensor, to determine if the load is balanced and draining properly. Incorrect voltage readings or lack of signal can trigger the error.

Symptoms:

The Kenmore washer displays a "uL" error code during the wash cycle, particularly with smaller loads. The cycle may stop prematurely, and the clothes may remain wet.

Possible Causes:

Unbalanced load detected by the washer's sensors.
Drain hose obstruction restricting water flow.
Faulty load sensing system.
Clogged drain pump filter.
Defective pressure switch.

Solution:

1

Unplug the washer from the outlet.
2

Inspect the drain hose for kinks or obstructions. Clear any blockages.
3

Check the drain pump filter for debris. It's typically located behind a small access panel at the bottom front of the washer. Use a 5/16-inch nut driver to remove the panel.
4

Verify the pressure switch hose is securely connected to the tub and the pressure switch. A loose connection can cause false readings.
5

Use a multimeter to test the pressure switch for continuity when the tub is empty and full. Refer to the washer's wiring diagram for correct terminal identification. Replace if faulty.
6

Check the wiring harness and connections to the main control board (MCU) for any loose or damaged wires. Repair or replace as needed.
7

Plug the washer back in and run a calibration cycle if available. Refer to the service manual for instructions.

Safety Warning:

Disconnect power to the washer before performing any repairs. Use Lock-Out/Tag-Out (LOTO) procedures to prevent accidental re-energizing of the circuit. Some components may retain a high voltage charge even after disconnection.

Prevention:

Avoid overloading the washer and distribute items evenly within the drum. Regularly clean the drain pump filter (every 3 months) and inspect the drain hose for kinks. Use HE (High Efficiency) detergent only.

Expert Tip:

Some Kenmore washers have a service mode that allows you to run diagnostic tests and calibration cycles. Refer to the service manual for the specific key sequence to enter service mode for your model.

Frequently Asked Questions

•How do I access the drain pump filter on my Kenmore washer?

The drain pump filter is usually located behind a small access panel at the bottom front of the washer. You'll likely need a flathead screwdriver or a 5/16-inch nut driver to remove the panel. Have a towel ready to catch any water that spills out when you remove the filter.

•What is the proper way to balance a load in my washing machine?

Distribute items evenly around the wash plate or agitator. Avoid washing single heavy items like rugs or blankets alone. If washing a single heavy item, add a few smaller items to help balance the load.

•Where can I find the service manual for my specific Kenmore washer model?

You can typically find the service manual online by searching for your washer's model number followed by "service manual" or "technical sheet". Websites like Appliance Parts Pros or ManualsLib often have these documents available for download. You can also try contacting Sears PartsDirect.
