Admiral Washer Stuck on Sensing Light: Troubleshooting... | appliancefaults.com

Technical Background:

The washing machine's Main Control Unit (MCU) uses several sensors to determine the load size and water level before initiating the wash cycle. These sensors include the pressure switch, load sensor (if equipped), and door lock mechanism. Voltage paths must be complete and within specified ranges for the MCU to progress through the cycle. Typically, the MCU looks for signals indicating an empty tub, a closed and locked door, and appropriate resistance readings from the load sensor.

Symptoms:

The Admiral washing machine starts, fills slightly, and then the sensing light remains illuminated for an extended period (30 minutes or more). The washer does not proceed to the wash cycle.

Possible Causes:

Clogged drain pump or drain hose
Faulty pressure switch
Defective load sensing system
Failed door lock mechanism
Issues with the main control board (MCU)
Excessive suds preventing accurate water level detection

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Check the drain hose for kinks or clogs. Disconnect the hose and inspect for obstructions. Clear any blockages.
3

Inspect the drain pump for debris. Remove the pump (usually secured with 1/4-inch screws or retaining clips) and check the impeller for obstructions.
4

Examine the pressure switch hose. Disconnect the hose from the tub and the pressure switch. Blow through the hose to ensure it's clear. Check the pressure switch connections using a multimeter, looking for continuity when the tub is empty, and a change in continuity when water is added.
5

Verify the door lock mechanism is functioning correctly. Use a multimeter to check for 120V AC at the door lock switch during the sensing phase.
6

Inspect wiring connections to the MCU and sensors. Look for loose connections or damaged wiring. Use a wiring diagram to trace voltage paths.
7

If all else fails, suspect a faulty MCU. Replacement may be necessary. Check the MCU voltage input, typically 5V DC or 12V DC.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Electrical components carry dangerous voltage. Use caution when working with electrical wiring.

Prevention:

Periodically clean the drain pump filter to prevent clogs. Use only HE (High Efficiency) detergent in the recommended amount to avoid excessive suds. Inspect the drain hose regularly for kinks or damage.

Expert Tip:

Many Admiral washers have a service mode. Entering this mode (usually by pressing a specific sequence of buttons) allows you to run diagnostic tests and error codes. Check the service manual for the specific sequence for your model.

Frequently Asked Questions

•Where is the pressure switch located on my Admiral washer?

The pressure switch is typically located near the top of the washer cabinet, often behind the control panel. It's connected to the tub via a small rubber hose.

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

The drain pump is usually accessible from the front of the washer, behind a lower access panel. You may need to remove a few screws to access the panel.

•What is the proper resistance reading for the door lock switch when the door is locked?

The resistance should be close to zero ohms when the door is locked, indicating a closed circuit. An open circuit (infinite resistance) suggests a faulty switch.
