Admiral Washer Sensing Light Flashing: Troubleshooting... | appliancefaults.com

Technical Background:

The washer's main control unit (MCU) relies on a series of sensors to determine the operating state. These sensors include the lid switch, water level pressure switch, and motor speed sensor. Voltage paths on the control board are typically 5V DC for logic and 120V AC for motor control. A flashing sensing light usually indicates an error in one of these sensor circuits.

Symptoms:

The Admiral washer's 'Sensing' light is flashing continuously, and the machine refuses to start a wash cycle. The user reports that the washer makes no sounds or attempts to fill with water.

Possible Causes:

Lid switch malfunction
Motor control unit (MCU) failure
Water inlet valve issues
Pressure switch problems
Wiring harness damage or loose connections
Main control board failure

Solution:

1

Unplug the washer from the outlet.
2

Inspect the lid switch for proper function. Use a multimeter to check for continuity when the lid is closed. If faulty, replace the lid switch.
3

Examine the water inlet valve screens for debris. Clean or replace the valve if necessary.
4

Check the pressure switch and hose for clogs or damage. Verify proper pressure readings using a manometer.
5

Test the motor control unit (MCU) and main control board for proper voltage. Use a multimeter to check for 120V AC at the power input and 5V DC at the logic outputs.
6

Inspect the wiring harness for any loose connections or damaged wires. Repair or replace any damaged wiring.
7

If all other components are functioning correctly, the main control board may be faulty and require replacement.

Safety Warning:

Disconnect power to the appliance before performing any repairs. High voltage is present in the control circuitry. Follow Lock-Out/Tag-Out (LOTO) procedures to prevent accidental power-up during servicing.

Prevention:

Regularly clean the lint filter and check the water inlet hoses for kinks or damage. Avoid overloading the washer and use the appropriate amount of detergent.

Expert Tip:

Many Admiral washers have a service mode that can display error codes. To enter service mode, try pressing and holding the 'Start/Pause' and 'Cycle Select' buttons simultaneously for 3 seconds while the washer is plugged in. Refer to the service manual for specific instructions.

Frequently Asked Questions

•What is the correct resistance reading for the lid switch when closed?

Ideally, the resistance should be close to 0 ohms, indicating a closed circuit. A reading above 1 ohm could indicate a faulty switch.

•How do I test the pressure switch using a multimeter?

Disconnect the hose from the pressure switch. Use a multimeter to check for continuity between the terminals when no pressure is applied. Then, gently blow into the pressure switch and check for a change in continuity. A faulty switch will not change state.

•Where can I find the wiring diagram for this specific Admiral washer model?

The wiring diagram is usually located inside the control panel or on the back of the washer cabinet. You can also search online using the washer's model number to find a downloadable PDF of the service manual.
