Maytag Washer Grinding Noise During Rinse Cycle:... | appliancefaults.com

Technical Background:

The MCU (Main Control Unit) controls all washer functions. During the rinse cycle, the MCU activates the drain pump to remove wash water and then fills the tub with fresh water for rinsing. Voltage (typically 120V AC) is sent to the drain pump motor via a relay on the MCU board. The pump then runs to expel the water.

Symptoms:

The homeowner reports a loud grinding noise emanating from the Maytag washer specifically during the rinse cycle. The washer otherwise functions normally during other cycles like wash and spin.

Possible Causes:

Foreign object lodged in the tub or pump.
Worn or damaged pump impeller.
Defective drain pump motor.
Worn or damaged tub bearings.
Drive belt issues (if applicable model).

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Inspect the drain pump for obstructions. Remove the lower access panel (usually with a 1/4-inch nut driver) and check the pump inlet and outlet hoses for foreign objects.
3

Remove the drain pump. Disconnect the hoses and wiring connector. Inspect the impeller for damage or wear.
4

Manually rotate the tub (with power off). Listen for grinding noises that indicate bad tub bearings.
5

If the drive belt is present, inspect it for wear, cracks, or looseness.
6

Test the drain pump motor with a multimeter, checking for continuity. A reading of infinity indicates a problem. Should read between 5-15 ohms generally.
7

Reassemble the washer, ensuring all connections are secure, and test the unit.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Use Lock-Out/Tag-Out (LOTO) procedures at the breaker panel to prevent accidental re-energization. Be aware of high voltage components within the washer.

Prevention:

Regularly clean the lint filter and inspect the tub for any foreign objects. Avoid overloading the washer, as this can put excessive strain on the bearings and pump. Use only HE (High Efficiency) detergent.

Expert Tip:

Many Maytag washers have a diagnostic mode. Consult the service manual or search online for the specific model's service mode activation sequence. Running the drain pump in diagnostic mode can help pinpoint the source of the noise.

Frequently Asked Questions

•How do I access the drain pump on my Maytag washer?

The drain pump is typically located behind an access panel at the bottom front or rear of the washer. You'll likely need a 1/4-inch nut driver or a Phillips head screwdriver to remove the panel. Refer to your washer's service manual for specific instructions.

•What is the typical lifespan of a drain pump in a washing machine?

The average lifespan of a drain pump is 5-10 years, but this can vary depending on usage and water quality. Hard water or frequent use can shorten the lifespan.

•What if the grinding noise is still present after replacing the drain pump?

If the noise persists after replacing the drain pump, the issue is likely with the tub bearings. Replacing tub bearings is a more complex repair and may require specialized tools. Consider calling a professional appliance technician.
