GE Profile GFW650 Washer uL Error: Balancing a Heavy Rug... | appliancefaults.com

Technical Background:

The MCU (Main Control Unit) monitors the drum's rotation speed and detects imbalances through a sensor, often a Hall-effect sensor or accelerometer. If the detected imbalance exceeds a pre-determined threshold, the MCU halts the cycle and displays the “uL” error. The motor control circuitry receives feedback about the drum's movement.

Symptoms:

The GE Profile GFW650 washer displays the “uL” error code and stops mid-cycle. The load may appear visibly unbalanced, or the washer may vibrate excessively.

Possible Causes:

Overloaded washer exceeding maximum capacity
Unevenly distributed load, particularly with bulky items like rugs or blankets
Washer not level on the floor
Worn or damaged suspension rods or springs
Defective load sensing system

Solution:

1

Unload the washer completely and redistribute the items, ensuring no overloading. Reduce the load size if washing heavy or bulky items like rugs.
2

Use a bubble level to check if the washer is level on the floor. Adjust the leveling legs using a wrench until the bubble is centered.
3

Manually spin the drum. If it wobbles excessively, inspect the suspension rods and springs for damage or wear. Replace as needed. Parts are available online.
4

Check the drain hose for obstructions. A partial blockage can affect the washer's ability to balance.
5

Run a calibration cycle (refer to the owner's manual for instructions). This resets the load sensing system.
6

Inspect the tub dampening straps/pads and look for wear or cracks.

Safety Warning:

Disconnect power to the washer at the breaker panel before performing any repairs. Lock Out / Tag Out (LOTO) procedures should be followed to prevent accidental energization. Be aware of potential pinch points during suspension component replacement.

Prevention:

Avoid overloading the washer. Distribute items evenly. Wash bulky items separately or in smaller loads. Periodically check the leveling legs and adjust as needed. Consider using a washing machine mat to reduce vibration.

Expert Tip:

Enter service mode by pressing and holding the Start/Pause button for 3 seconds, then simultaneously pressing the Temp and Spin buttons. This allows access to diagnostic codes and calibration settings.

Frequently Asked Questions

•How do I access the suspension rods for inspection and replacement?

Typically, you'll need to remove the top panel of the washer. This often involves removing screws at the back or sides of the top panel. With the top panel removed, you should have clear access to the suspension rods.

•What is the maximum load capacity of the GE GFW650 washer?

The GE GFW650 has a load capacity of approximately 4.8 cubic feet. Refer to the owner's manual for precise weight limits, usually specified in pounds.

•Where is the load sensor located and how can I test it?

The load sensor is generally integrated into the motor control board or the main control board. Testing the load sensor requires a multimeter and the washer's service manual for specific resistance or voltage readings to compare against. Often, the board requires replacement if the sensor is the culprit.
