Admiral Washer Not Finishing Cycle: Troubleshooting... | appliancefaults.com

Technical Background:

Modern washing machines use a Motor Control Unit (MCU) to manage all aspects of the wash cycle. The MCU receives input from various sensors (pressure switch, motor speed sensor) and controls the motor, water valves, and drain pump. Voltage paths are critical; the MCU needs proper voltage (typically 5V DC and 12V DC internally) to operate correctly. The pressure switch signals the water level to the MCU. Faulty voltage readings to the MCU lead to cycle interruption.

Symptoms:

The washer starts a cycle, but gets stuck in the sensing phase or fails to complete the wash, rinse, or spin cycles. The control panel may display an error code or simply freeze.

Possible Causes:

Clogged drain pump filter
Faulty pressure switch
Defective motor control unit (MCU)
Obstruction in the drain hose
Worn or broken drive belt (if applicable)
Unbalanced load preventing spin cycle initiation

Solution:

1

Unplug the washer from the outlet to prevent electrical shock. Follow Lock Out Tag Out procedures.
2

Inspect the drain hose for kinks or obstructions. Disconnect the hose and clear any blockages.
3

Clean the drain pump filter. Locate the access panel (usually at the bottom front of the washer), remove the filter, and rinse it thoroughly.
4

Check the pressure switch hose for clogs or damage. Disconnect the hose from the pressure switch and blow through it to ensure it's clear.
5

Verify the voltage at the pressure switch with a multimeter set to read AC voltage when the washer is supposedly filling. Expect to see 120V AC.
6

Examine the drive belt (if applicable) for wear or breakage. Replace if necessary.
7

Test the motor and motor control unit. This might require a qualified technician with specialized testing equipment.

Safety Warning:

Disconnect power to the appliance before performing any repairs. High voltage is present in the control panel and motor areas. Lock Out Tag Out procedures MUST be followed to ensure the breaker powering the outlet cannot be accidentally switched on.

Prevention:

Regularly clean the drain pump filter (every 3 months). Avoid overloading the washer. Use the correct amount of detergent. Inspect hoses annually for signs of wear or damage.

Expert Tip:

Many Admiral washers have a service mode. Try entering service mode (consult the service manual or online resources for the specific key combination for your model) and running a diagnostic test cycle. This can often pinpoint the faulty component.

Frequently Asked Questions

•How do I access the service mode on my Admiral washer?

The service mode entry sequence varies by model. Consult your washer's service manual (usually available online) or search online forums for the specific key combination for your model.

•How do I test the pressure switch?

A simple test involves using a multimeter to check for continuity across the pressure switch terminals when the tub is empty and then when it is full of water. The switch should change state (open or closed) depending on the water level. Refer to your washer's wiring diagram for the correct terminals.

•Where can I find a replacement MCU for my Admiral washer?

Replacement MCUs can be purchased from appliance parts retailers online or from local appliance parts stores. You'll need the model number of your washer to ensure you get the correct replacement part.
