Whirlpool Cabrio WTW5000DW Loud Jet Engine Noise at 1200... | appliancefaults.com

Technical Background:

The Motor Control Unit (MCU) regulates the motor speed using feedback from a speed sensor. High-speed spin relies on precise motor control and a balanced load. Mechanical failures in the drive components amplify noise during high RPM operation. Voltage typically measures 120V AC at the motor windings during operation.

Symptoms:

US homeowner reports a loud 'jet engine' noise emanating from the Whirlpool Cabrio WTW5000DW washing machine, particularly noticeable during the 1200 RPM spin cycle.

Possible Causes:

Worn or damaged tub bearing
Failed or loose drive pulley
Foreign object lodged between tubs
Defective motor coupling
Damaged or unbalanced drive shaft

Solution:

1

Disconnect power to the washing machine at the breaker panel.
2

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

Inspect the drive pulley for cracks or looseness. Tighten or replace as needed.
4

Examine the tub bearing by manually spinning the inner tub. Listen for grinding or rough sounds.
5

If bearing noise is present, remove the inner tub and inspect the bearing assembly. Replace the bearing assembly if damaged.
6

Check for any foreign objects lodged between the inner and outer tubs. Remove any obstructions.
7

Verify the motor coupling is intact and securely connected. Replace if damaged.

Safety Warning:

Lock Out/Tag Out (LOTO) the breaker before servicing. High voltage is present when the machine is powered. Discharge the capacitor if equipped, before touching any electrical components.

Prevention:

Avoid overloading the washing machine. Regularly clean the tub and check for foreign objects in the drum. Inspect the drive pulley and motor coupling annually for wear and tear. Use appropriate HE detergent.

Expert Tip:

Enter service mode by pressing and holding the START/PAUSE button, then pressing POWER/ON/OFF button 3 times in quick succession. This allows you to run diagnostic tests and error code retrieval.

Frequently Asked Questions

•How do I remove the inner tub to access the tub bearing?

First, disconnect the power and water supply. Remove the agitator or impeller, then remove the wash plate. You'll need a spanner wrench to loosen the tub retaining nut. Once removed, you should be able to lift the inner tub out. Be sure to protect the splines from damage.

•What type of grease should I use on the tub bearing?

Use a high-quality, waterproof, and heat-resistant bearing grease specifically designed for washing machine applications. Lithium-based grease is generally a good choice.
