Admiral Washer Wash and Rinse Lights Flashing:... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) monitors various sensors and components within the washing machine to ensure proper operation. When the Wash and Rinse lights flash together, it indicates the MCU has detected a fault within one of these systems. These components include the door lock switch, pressure switch, drain pump, and water inlet valve. The MCU relies on voltage readings and continuity signals from these components to determine their status. Incorrect voltages or open/closed circuits trigger the error code.

Symptoms:

The homeowner reports that the Wash and Rinse lights on their Admiral washing machine are flashing simultaneously. The machine may not start, fill, drain, or spin.

Possible Causes:

Faulty door lock switch
Pressure switch malfunction
Clogged drain pump or drain hose
Defective water inlet valve
Main Control Unit (MCU) failure
Wiring harness issue (loose connection or damaged wire)

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Check the door lock switch for continuity using a multimeter. It should show continuity when the door is closed and locked.
3

Inspect the drain pump for obstructions. Remove any debris and ensure the impeller spins freely.
4

Verify the pressure switch is not clogged or damaged. Use a multimeter to check for continuity when the tub is empty and full.
5

Examine the water inlet valve for proper operation. Test for 120V AC at the valve during the fill cycle. Replace if faulty.
6

Check the wiring harness connections to the door lock, pressure switch, drain pump, and water inlet valve. Repair any loose or damaged wires.
7

If all components test good, replace the Main Control Unit (MCU).

Safety Warning:

Always disconnect the appliance from the power supply before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. High voltage is present in certain components. If you are not comfortable working with electricity, consult a qualified appliance repair technician.

Prevention:

• Regularly clean the drain pump filter to prevent clogs.
• Avoid overloading the washer to prevent strain on the motor and other components.
• Inspect the water inlet hoses for leaks and replace them every 5 years.

Expert Tip:

Try entering service mode by pressing and holding the Start/Pause button for 3 seconds, then pressing the Power button. This might display a more specific error code on the display, narrowing down the source of the problem.

Frequently Asked Questions

•What is the resistance range for a healthy door lock switch on this Admiral washer?

A healthy door lock switch should have close to 0 ohms resistance when locked, indicating a closed circuit. An open circuit (infinite resistance) when locked indicates a faulty switch.

•How do I access the drain pump on this Admiral washer model to check for clogs?

Typically, the drain pump is accessible from the front of the washer, behind a small access panel at the bottom. You'll likely need a flathead screwdriver to remove the panel. Have a towel ready to catch any water that may spill out.

•Where is the Main Control Unit (MCU) located in this Admiral washer, and what tools are needed to access it?

The MCU is usually located behind the control panel at the top of the washer. You will need a Phillips head screwdriver and possibly a 1/4-inch nut driver to remove the control panel and access the MCU. Be careful not to damage any wires during removal.
