Speed Queen Washer Roaring Noise: Troubleshooting and... | appliancefaults.com

Technical Background:

The washer's MCU (Main Control Unit) controls the motor speed and direction. Excessive noise often indicates a mechanical failure in the drivetrain or water pump. The MCU sends signals to the motor control board, which regulates the voltage to the motor windings. A faulty bearing increases the motor's current draw, but the MCU usually doesn't detect these nuanced mechanical failures directly; it relies on monitoring motor speed and current within programmed tolerances.

Symptoms:

The homeowner describes a loud roaring noise emanating from the Speed Queen washer during operation, resembling the sound of a jet engine.

Possible Causes:

Worn or damaged tub bearing
Failing motor bearing
Object lodged between the spin basket and outer tub
Worn or loose drive pulley
Worn or damaged pump impeller

Solution:

1

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

Remove the top panel of the washer using a 1/4-inch nut driver.
3

Visually inspect the tub bearing area for signs of rust, wear, or damage. Look for discoloration or residue indicating bearing failure.
4

Check the motor bearing by manually rotating the motor pulley. Listen for any grinding or unusual noises. Replace the motor if the bearing is faulty.
5

Inspect between the spin basket and outer tub for any foreign objects. You may need to remove the spin basket for a thorough inspection. Use a spanner wrench if required.
6

Check the drive pulley for wear or looseness. Tighten the pulley bolt with a 1/2-inch socket. Replace if worn.
7

Inspect the pump impeller for damage. If damaged, replace the pump assembly. Check the pump housing for obstructions.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Use proper Lock-Out/Tag-Out (LOTO) procedures. High voltage components are present. Ensure the capacitor is discharged before handling the motor.

Prevention:

Regularly inspect the tub bearing area for leaks. Avoid overloading the washer. Use HE (High Efficiency) detergent in the correct amount. Periodically run an empty washer cycle with a washing machine cleaner.

Expert Tip:

To enter service mode on some Speed Queen models, press and hold the Start/Pause button, then press the Cycle Selector knob three times within five seconds. This will allow you to run diagnostic tests and view error codes. Use this to verify sensor readings (pressure switch, motor RPM).

Frequently Asked Questions

•What type of grease should I use for the tub bearing if I need to re-grease it?

Use a high-quality, waterproof, lithium-based grease specifically designed for appliance bearings. Avoid using general-purpose grease, as it may not withstand the harsh conditions inside the washing machine.

•How do I remove the spin basket to check for objects underneath?

First, remove the agitator (if applicable) and the fabric softener dispenser. Then, use a spanner wrench to loosen the spin basket nut. Once the nut is removed, you should be able to lift the spin basket out. Be careful not to damage the basket or the surrounding components.

•What is the typical lifespan of a Speed Queen tub bearing?

With proper maintenance and use, a Speed Queen tub bearing can last for 10-15 years or more. However, overloading the washer, using incorrect detergents, or neglecting leaks can significantly shorten its lifespan.
