Admiral Washer Fills and Immediately Drains:... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) controls the fill and drain cycles. It relies on signals from the water level pressure switch to determine when the tub is full. The MCU then de-energizes the fill valve and prepares for the wash cycle. If the drain pump is continuously energized, or if the water level signal is incorrect, the washer will immediately drain.

Symptoms:

The Admiral washing machine starts filling with water as expected, but instead of proceeding with the wash cycle, the water immediately drains out. This may occur continuously or intermittently. The washer may display an error code or simply fail to start.

Possible Causes:

Clogged drain hose or standpipe.
Faulty drain pump continuously running.
Defective water level pressure switch.
Siphoning effect due to improper drain hose system.
Malfunctioning Main Control Unit (MCU) or motor control board.
Damaged or mispositioned drain valve.

Solution:

1

Disconnect power to the washer at the breaker panel (LOTO).
2

Inspect the drain hose for kinks or clogs. Disconnect it from the standpipe and check for obstructions.
3

Check the standpipe. It should be at least 30 inches high and no more than 96 inches.
4

Access the drain pump (usually at the bottom front or rear of the machine). Inspect for debris and check the wiring connections.
5

Use a multimeter to test the drain pump for continuity. A reading of approximately 10-20 ohms is typical.
6

Locate the water level pressure switch and its air hose. Check for cracks, kinks, or obstructions. Use a manometer to verify the switch is operating correctly.
7

Examine the MCU for burnt components or water damage. If suspected, consider replacement or licensed technician repair.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before attempting any repairs. Washing machines operate on 120V AC, which can cause serious injury or death. Follow Lock-Out/Tag-Out (LOTO) procedures to ensure the power remains off during the repair process.

Prevention:

Regularly inspect the drain hose for kinks and clogs. Periodically clean the drain pump filter (if accessible). Ensure the drain hose is properly installed and secured to prevent siphoning. Avoid overloading the washer, as this can strain the drain pump.

Expert Tip:

Many Admiral washers have a service mode that allows you to run diagnostic tests on individual components. To access the service mode, rapidly press a combination of buttons (refer to the service manual for your specific model – often involves pressing and holding the start button along with another button like cycle select for a few seconds). This can help isolate the faulty component.

Frequently Asked Questions

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

The drain pump is typically located at the bottom front or back of the washing machine. You may need to remove an access panel or tilt the machine to gain access. Consult your owner's manual for specific instructions.

•What is the proper height for the drain standpipe?

The drain standpipe should be a minimum of 30 inches and a maximum of 96 inches high. This prevents siphoning and ensures proper drainage.

•How do I test the water level pressure switch?

First, disconnect the air hose from the switch and check for any cracks or blockages. Then, use a manometer to apply pressure to the switch and verify that it switches contacts at the correct pressure levels. A multimeter can be used to test continuity across the switch terminals.
