Whirlpool Cabrio Washer: How to Fix Loud Jet Engine... | appliancefaults.com

Technical Background:

The Whirlpool Cabrio washer utilizes a Motor Control Unit (MCU) to regulate the speed and direction of the motor. During the spin cycle, the MCU sends a variable voltage (typically 0-120V AC) to the motor windings, controlling its speed. Proper function depends on feedback from sensors such as the load size sensor and motor speed sensor. Any mechanical resistance, such as bad bearings, will increase the load on the motor and potentially cause unusual noises.

Symptoms:

The homeowner reports a very loud noise during the spin cycle, described as sounding like a 'jet engine.' This noise is significantly louder than normal operation.

Possible Causes:

Worn or damaged tub bearings
Failed motor coupling
Debris caught between the tubs
Worn drive belt (if applicable, some models use direct drive)
Damaged motor windings
Loose or unbalanced load

Solution:

1

Unplug the washer from the 120V AC outlet. Lock Out/Tag Out (LOTO) procedures MUST be followed.
2

Access the washer's cabinet by removing the rear panel using a 1/4-inch nut driver.
3

Inspect the motor coupling (if applicable). Look for signs of wear, cracks, or breakage. Replace if damaged.
4

Check the drive belt (if applicable) for wear, fraying, or looseness. Replace if necessary.
5

Manually rotate the inner tub. Listen for grinding or rumbling sounds, which indicate bad tub bearings.
6

If bearings are suspected, the entire tub assembly may need replacement. This is a significant repair.
7

Before reassembly, check for any foreign objects lodged between the inner and outer tubs.

Safety Warning:

Disconnect power to the appliance before performing any repairs. Use proper Lock Out/Tag Out (LOTO) procedures. High voltage is present in the control panel and motor circuits. Seek qualified assistance if you are not comfortable working with electrical appliances.

Prevention:

Regularly check and clean the drain pump filter to prevent debris buildup. Avoid overloading the washer to minimize stress on the motor, bearings, and other components. Periodically inspect the drive belt (if applicable) for wear.

Expert Tip:

Enter service mode by pressing the following sequence within 6 seconds: PRESS AND HOLD START/PAUSE then PRESS POWER-TEMP-SOIL LEVEL-TEMP-SOIL LEVEL. This will allow you to run diagnostic tests and check for error codes beyond what the user interface displays.

Frequently Asked Questions

•How difficult is it to replace the tub bearings on a Cabrio washer?

Replacing tub bearings on a Cabrio washer is a challenging repair. It often requires specialized tools, such as a spanner wrench and bearing puller. Due to the complexity and potential for damage, it's often more cost-effective to replace the entire tub assembly or even the washer itself.

•What are the common failure modes for the motor coupling?

The motor coupling typically fails due to wear and tear from the repeated starting and stopping of the motor, especially under heavy loads. Common failure modes include cracking, splitting, or complete separation of the rubber or plastic components that connect the motor to the transmission.

•How can I tell if the noise is coming from the motor itself rather than the bearings?

To isolate the noise, disconnect the drive belt (if applicable) or motor coupling. Then, manually spin the tub. If the noise is still present, it's likely coming from the bearings. If the noise is gone, start the motor briefly with the belt/coupling disconnected. If the noise is present now, the motor is the likely culprit.
