Maytag Washer Beeping 4 Times Mid-Wash: Troubleshooting... | appliancefaults.com

Technical Background:

The washer's main control unit (MCU) monitors various sensors and components during the wash cycle. A specific fault, like a drain issue, low voltage on the motor windings, or door lock failure, triggers the 4-beep error. The MCU interprets voltage signals from these components and initiates the error sequence to alert the user.

Symptoms:

The Maytag washer stops mid-cycle and beeps 4 times repeatedly. The display may or may not show an error code, but the beeping is the primary indicator. The drum may contain water, or it might be empty.

Possible Causes:

Over sudsing detected during the wash cycle.
Drain pump failure or blockage.
Pressure sensor malfunction indicating incorrect water level.
Motor control unit (MCU) communication error.
Door lock switch failure.
Clogged drain line.

Solution:

1

Disconnect power to the washer at the breaker panel.
2

Inspect the drain hose for kinks or clogs. Remove and flush with water.
3

Check the drain pump for obstructions. Remove the pump and clean out any debris (coins, lint, etc.).
4

Verify the pressure sensor hose is securely connected to the tub and the pressure sensor. Check for cracks or damage.
5

Inspect the door lock switch for proper operation. Use a multimeter to check for continuity when the door is locked (120V AC present).
6

Check the wire harness connections to the motor control unit (MCU) for loose connections or corrosion.
7

If the problem persists, replace the drain pump or pressure sensor.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. High voltage is present in the control panel and motor circuits. Lockout/Tagout (LOTO) procedures are recommended to ensure the circuit breaker remains off during servicing.

Prevention:

Use only High-Efficiency (HE) detergent in the recommended amount. Periodically run a washer cleaning cycle with a washer cleaner product. Inspect drain hoses regularly for wear and tear.

Expert Tip:

Some Maytag washers have a service mode that allows you to run diagnostic tests. Typically, you can enter service mode by pressing a specific sequence of buttons on the control panel (e.g., Power, then pressing Start/Pause three times within 5 seconds, followed by Power again).

Frequently Asked Questions

•Where is the drain pump located on my Maytag washer?

The drain pump is typically located at the bottom of the washer, behind an access panel. You might need a 1/4-inch nut driver to remove the access panel.

•How do I test the door lock switch with a multimeter?

Disconnect power to the washer. Locate the door lock switch and its wiring harness. Set your multimeter to the continuity setting. With the door locked (simulated), place the multimeter probes on the appropriate terminals of the switch. You should see continuity (a reading close to zero ohms). If not, the switch is likely faulty.

•What is HE detergent, and why is it important?

HE detergent is High-Efficiency detergent. It produces fewer suds than regular detergent. Using regular detergent in an HE washer can cause excessive sudsing, which can trigger the 4-beep error and damage the washer. Always use the recommended amount of HE detergent.
