Speed Queen Washer Tub Hitting Sides During Spin Cycle:... | appliancefaults.com

Technical Background:

The MCU (Main Control Unit) monitors the motor speed and tub position via sensors. If an imbalance is detected, the MCU will attempt to adjust the spin cycle or, in severe cases, stop the cycle to prevent damage. Voltage is supplied to the motor and drain pump via relays controlled by the MCU.

Symptoms:

The homeowner reports that the Speed Queen washer's tub is hitting the sides of the cabinet during the spin cycle, creating excessive noise and vibration.

Possible Causes:

Uneven loading of laundry.
Worn or damaged suspension springs/rods.
Failed snubber or damper pad.
Unlevel machine position.
Damaged or loose tub bearing.

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Visually inspect the suspension springs/rods for damage or breakage. Replace if necessary.
3

Check the snubber or damper pad (usually located at the base of the tub) for wear or disintegration. Replace if needed.
4

Use a level to ensure the washer is level, adjust the leveling feet as required using an adjustable wrench.
5

Manually spin the tub and listen for any unusual noises indicating a bad tub bearing. If noises are present, bearing replacement may be needed; this often requires significant disassembly.
6

Remove the top panel (usually secured with screws at the rear) to inspect the top suspension components more thoroughly.
7

After repairs, run a test cycle with a balanced load to confirm proper operation.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. High voltage components are present inside the unit; exercise caution to avoid electrical shock.

Prevention:

Avoid overloading the washer and distribute laundry evenly in the tub. Periodically check the leveling feet to ensure the machine remains level. Avoid washing excessively heavy items that may stress the suspension components.

Expert Tip:

Some Speed Queen models have a service mode that allows for diagnostic testing and calibration. Consult the service manual for the specific procedure for your model. Often, you can access the service mode by pressing a specific sequence of buttons on the control panel, such as holding the start button and pressing another button 3 times.

Frequently Asked Questions

•What are the common signs of a worn tub bearing?

Common signs include a grinding or roaring noise during spin, excessive vibration, and potential water leakage around the tub seal.

•How do I access the snubber or damper pad on my Speed Queen washer?

Accessing the snubber usually involves tilting the washer back after disconnecting power and water. It's typically located underneath the tub, near the center.

•What type of grease should I use on the leveling feet threads to prevent them from seizing?

Use a silicone-based grease or anti-seize compound on the threads. Avoid petroleum-based products, as they can degrade the rubber feet over time.
