Whirlpool Washer Chirping Noise During Agitation:... | appliancefaults.com

Technical Background:

The Motor Control Unit (MCU) controls the motor speed and direction during the wash and spin cycles. The MCU sends varying voltage (typically 0-120V AC) to the motor windings. Mechanical components like the agitator, drive block, and tub bearing convert this electrical energy into mechanical motion. Friction or wear in these components can cause unusual noises.

Symptoms:

US homeowner reports a chirping or squeaking noise, resembling a bird, coming from the Whirlpool washing machine specifically during the agitation cycle. The noise may be intermittent or constant during agitation.

Possible Causes:

Worn or damaged agitator dogs (pawls)
Worn or dry drive block (splutch kit)
Defective motor coupling
Worn tub seal or bearing
Foreign object trapped in the pump
Dry or failing transmission

Solution:

1

Unplug the washer from the 120V AC outlet and turn off the water supply.
2

Remove the agitator cap and any fabric softener dispenser. Use a 7/16-inch socket to remove the agitator bolt.
3

Lift out the agitator. Inspect the agitator dogs (pawls) for wear or damage. Replace if necessary.
4

If the agitator dogs are fine, inspect the drive block (splutch kit) underneath the wash plate. Look for signs of wear or breakage. Replace if needed.
5

If the noise persists, check the motor coupling between the motor and transmission. It may be cracked or worn. Replace it.
6

Listen closely to the tub bearing during agitation. If the bearing is the source of the noise, replacing the entire outer tub assembly is typically required.
7

Inspect and clean the drain pump for any obstructions or debris using a flat-head screwdriver. Reassemble and test.

Safety Warning:

Always disconnect the power supply (unplug the washer) before performing any repairs. High voltage is present when the machine is plugged in. Follow Lock-Out/Tag-Out (LOTO) procedures to ensure the machine is not accidentally powered on during repairs.

Prevention:

Periodically inspect and clean the washing machine. Avoid overloading the washer, as this can stress the mechanical components. Use the appropriate amount of detergent. Run a washer cleaner cycle every month to help prevent buildup and maintain smooth operation.

Expert Tip:

Many Whirlpool washers have a diagnostic mode. To access it, consult the service manual for your specific model. A common sequence involves pressing a specific combination of buttons (e.g., start, cancel, start, cancel) within a short time frame. This mode can display error codes and allow you to run diagnostic tests on various components.
