Hotpoint Washer Sounds Like a Jet Engine During Spin... | appliancefaults.com

Technical Background:

The washer's MCU (Main Control Unit) controls the motor speed and direction during the spin cycle. Voltage is applied to the motor windings to achieve high-speed rotation. Worn components or obstructions can cause the motor to work harder, resulting in increased noise and vibration.

Symptoms:

The Hotpoint washer makes a loud, high-pitched noise during the spin cycle, resembling a jet engine taking off. The noise may increase in intensity as the spin cycle progresses.

Possible Causes:

Worn or damaged tub bearings
Foreign object lodged in the drain pump or between the tubs
Failing motor coupling or direct drive motor
Worn drive belt (if applicable)
Damaged snubber or suspension components

Solution:

1

Disconnect power to the washer by unplugging it from the outlet.
2

Access the washer's cabinet (usually by removing rear or side panels with a 1/4-inch nut driver).
3

Inspect the tub bearings for play or roughness. Rotate the inner tub by hand. Excessive noise or resistance indicates bearing failure.
4

Examine the drain pump. Remove any visible obstructions. Check for impeller damage.
5

If applicable, inspect the drive belt for cracks or wear. Check the motor coupling for damage. A faulty motor coupling will need replacement.
6

Check the snubber pads or suspension rods for wear or breakage. These components dampen vibrations during the spin cycle.
7

Reassemble the washer and test the spin cycle. If the noise persists, further component replacement may be required.

Safety Warning:

Disconnect the power supply to the washer before performing any repairs. Capacitors can hold a dangerous electrical charge even after the unit is unplugged. Use extreme caution when working around electrical components. Follow Lock Out/Tag Out (LOTO) procedures.

Prevention:

Regularly check and clean the drain pump filter. Avoid overloading the washer. Use the correct type and amount of detergent. Periodically inspect suspension components for wear.

Expert Tip:

Many Hotpoint washers have a diagnostic mode that can display error codes. Consult the service manual to access the diagnostic mode and interpret any error codes displayed. This can help pinpoint the source of the noise.

Frequently Asked Questions

•How do I access the diagnostic mode on my Hotpoint washer?

The procedure varies depending on the model. Typically, it involves pressing a specific sequence of buttons on the control panel within a short time frame. Consult the service manual or search online for your specific model number.

•What type of grease should I use when replacing tub bearings?

Use a high-quality, waterproof, high-temperature bearing grease. Avoid using general-purpose grease, as it may not withstand the harsh conditions inside the washer.

•How do I determine if the noise is coming from the motor or the tub bearings?

Remove the drive belt (if applicable) and spin the motor and tub independently. If the noise persists when spinning the tub, the bearings are likely the problem. If the noise is present when running the motor without the belt, the motor is the likely cause.
