Speed Queen Top Load Washer Out of Balance Error:... | appliancefaults.com

Technical Background:

The MCU monitors the load balance through a load sensor. This sensor sends a voltage signal to the MCU. If the MCU detects an imbalance based on this signal and the basket's movement monitored via an encoder, it triggers the out of balance error and stops the cycle. Voltage paths associated with the load sensor and motor control circuit are critical for diagnosis.

Symptoms:

The homeowner observes the Speed Queen top load washer stopping mid-cycle and displaying an out of balance error code. The washer may also shake violently during the spin cycle. Repeated attempts to restart the cycle result in the same error.

Possible Causes:

Unevenly distributed load in the wash basket.
Washer not level on the floor.
Worn or damaged suspension rods.
Defective basket drive or clutch assembly.
Faulty load sensor or MCU (Main Control Unit).

Solution:

1

Unplug the washer from the 120V AC outlet and turn off the water supply.
2

Manually redistribute the load in the wash basket, ensuring items are evenly spaced.
3

Use a level to check if the washer is level. Adjust the leveling legs as needed using an adjustable wrench.
4

Inspect the suspension rods for wear or damage. Replace any worn or damaged rods.
5

Visually inspect the basket drive and clutch assembly for any signs of damage or wear.
6

Check the wiring harness and connections to the load sensor and MCU for loose connections or damage. Use a multimeter to check the load sensor voltage output, comparing it to the service manual specifications. Expected voltage will be around 5V DC.
7

If the problem persists, the MCU may be faulty and require replacement. Refer to the service manual for replacement procedures.

Safety Warning:

Disconnect power before servicing. Lock-out/Tag-out (LOTO) procedures should be followed to prevent accidental energization. Some components carry 120V AC. Exercise extreme caution.

Prevention:

Avoid overloading the washer. Distribute clothes evenly in the wash basket. Regularly check the leveling legs to ensure the washer remains level. Inspect the suspension rods periodically for signs of wear.

Expert Tip:

On some Speed Queen models, you can access the service mode by pressing and holding the Start/Pause button for 5 seconds while simultaneously pressing the cycle select button 3 times. This can provide diagnostic information or allow you to run test cycles.

Frequently Asked Questions

•What is the resistance value of a healthy load sensor on this Speed Queen model?

The resistance value of a healthy load sensor typically ranges from 1k to 5k ohms. Consult the service manual for the specific value for your model.

•How do I test the suspension rods to determine if they are worn?

Visually inspect the suspension rods for any signs of wear, such as cracks, bending, or excessive play. You can also try manually bouncing the wash basket. If the basket continues to bounce excessively after being released, the suspension rods may be worn.

•Where is the MCU (Main Control Unit) located in this washer?

The MCU is usually located behind the control panel, near the top of the washer. You may need to remove the control panel to access it.
