Admiral Washer Diagnostic Mode: Understanding Blinking... | appliancefaults.com

Technical Background:

Admiral washers use a Main Control Unit (MCU) to manage the wash cycle. The MCU monitors various sensors and components, like the door lock, pressure switch, and motor. Error codes, indicated by blinking lights, signal malfunctions detected by the MCU. The MCU receives voltage feedback from sensors, and if a sensor reports an out-of-range value or no voltage, the MCU triggers an error.

Symptoms:

The Admiral washer won't start, stops mid-cycle, or displays blinking lights on the control panel.

Possible Causes:

Failed door lock switch
Faulty pressure switch
Defective motor control unit (MCU)
Blocked drain pump or drain hose
Loose wiring connections
Failed water inlet valve

Solution:

1

Unplug the washer from the 120V AC outlet.
2

Access the MCU, usually behind the control panel. Use a 1/4-inch nut driver to remove screws.
3

Check wiring harness connections to the MCU. Look for loose or corroded wires.
4

Locate the service diagnostic chart, often inside the control panel or back panel.
5

Plug the washer back in and observe the blinking light sequence. Compare the sequence to the diagnostic chart.
6

Based on the error code, test the suspected component (e.g., door lock switch) with a multimeter for continuity.
7

If the component is faulty, replace it. Reassemble the washer and test.

Safety Warning:

Disconnect power before servicing. Capacitors in the MCU can hold a charge even when unplugged. Wear appropriate safety glasses. Lock Out/Tag Out (LOTO) procedures must be followed.

Prevention:

- Regularly clean the drain pump filter to prevent clogs.

• Use the correct amount of HE detergent.

• Inspect hoses for cracks or leaks.

• Avoid overloading the washer.

Expert Tip:

Many Admiral washers have a service mode activated by pressing a specific sequence of buttons (e.g., Power, then Start/Pause three times within 5 seconds). Entering service mode allows manual testing of components.

Frequently Asked Questions

•How do I find the diagnostic chart for my specific Admiral washer model?

The diagnostic chart is usually located inside the control panel, behind the back panel, or sometimes inside the washer's cabinet. If you cannot find it there, search online using your washer's model number, or contact Admiral customer support.

•What voltage should I expect to see at the water inlet valve?

The water inlet valve typically operates on 120V AC. Use a multimeter to measure the voltage when the washer is filling. If you don't read 120V AC, the MCU may not be sending the signal, or there is a wiring problem.

•How do I properly test the door lock switch for continuity?

Unplug the washer. Disconnect the wires from the door lock switch. Set your multimeter to the continuity setting. Test between the appropriate terminals (refer to the wiring diagram). You should see continuity when the door is locked and no continuity when the door is unlocked. If this is not the case, replace the door lock switch.
