Hotpoint Washer Drive Belt Chirping Sound: Troubleshootin... | appliancefaults.com

Technical Background:

The Motor Control Unit (MCU) controls the motor speed and direction. Voltage is sent from the MCU to the motor windings to engage the motor. The belt then transfers the rotational force from the motor to the drum assembly. Excessive friction in the belt path causes the chirping sound. A misaligned or damaged pulley or motor will cause friction and wear on the belt assembly.

Symptoms:

The homeowner reports a chirping or squealing sound coming from the washing machine during the spin cycle. The noise may be intermittent or constant, and its intensity may vary depending on the load size.

Possible Causes:

Worn or cracked drive belt
Misaligned motor pulley or drum pulley
Foreign object lodged between the belt and pulley
Worn or seized drum support bearings
Excessive load causing belt slippage

Solution:

1

Disconnect the washer from the power supply. Unplug it from the outlet and verify with a multimeter that there is 0V AC at the receptacle.
2

Locate the drive belt. This usually requires removing the rear access panel (secured with 1/4-inch screws).
3

Inspect the drive belt for wear, cracks, or damage. Check the belt tension.
4

Check the alignment of the motor pulley and drum pulley. Use a straight edge to verify alignment.
5

Manually rotate the drum. Listen for any unusual noises that may indicate worn drum support bearings.
6

Replace the drive belt with a new belt if it is worn or damaged. Ensure the new belt is properly seated on the pulleys.
7

Reassemble the washer and test its operation through a full wash cycle.

Safety Warning:

Always disconnect the power supply before performing any repairs. Washing machines contain high voltage components that can cause serious injury or death. Follow Lock Out Tag Out (LOTO) procedures.

Prevention:

Avoid overloading the washing machine. Regularly inspect the drive belt for wear and replace it as needed. Keep the area around the washing machine clean and free of debris.

Expert Tip:

To check the motor windings for shorts to ground, use an ohmmeter. Place one lead on each terminal of the motor winding, and the other on the motor casing. There should be no continuity present.

Frequently Asked Questions

•How do I determine the correct replacement drive belt for my Hotpoint washer?

Locate the model number on the washer's cabinet. Use this model number to find the correct replacement drive belt from a reputable appliance parts supplier. Online part retailers or local appliance repair shops can assist.

•What is the proper tension for a new drive belt?

Drive belt tension should allow for approximately 1/2 inch of deflection when pressed midway between the pulleys. Too tight can cause premature wear, and too loose can cause slippage.

•How can I tell if the drum support bearings are failing?

Spin the drum by hand with the drive belt removed. Listen for grinding or squealing noises, and feel for excessive play or wobble in the drum. Bearing failure often presents as a loud rumbling sound during spin cycles.
