Admiral Washer: Water Level Sensor Tube Clogged -... | appliancefaults.com

Technical Background:

MCU logic and voltage paths.

The water level sensor uses air pressure in the tube to measure the water level in the tub. The sensor sends a voltage signal (typically 0-5V DC) to the Main Control Unit (MCU). The MCU interprets this voltage to determine when to stop filling and proceed with the wash cycle. A clogged tube prevents accurate pressure readings, leading to incorrect water levels and cycle disruptions.

Symptoms:

US homeowner observations.

Homeowners report the washer is either overfilling, filling very slowly, or stopping mid-cycle with a water level error. Clothes are sopping wet after the cycle finishes and error lights appear on the control panel. Some users report the washer fills and drains simultaneously, never advancing to the next cycle step.

Possible Causes:

Soap scum buildup in the water level sensor tube.
Kinked or damaged water level sensor tube.
Loose connection between the tube and the sensor or tub.
Defective water level sensor.
Clogged air dome where the tube connects to the tub.
Faulty wiring harness between the water level sensor and the MCU.

Solution:

1

Disconnect the washer from the breaker panel. Use a multimeter to verify 0V AC at the outlet.
2

Locate the water level sensor, typically behind the control panel or inside the main cabinet. Refer to the service manual for your specific Admiral model.
3

Identify the small rubber tube connecting the sensor to the outer tub.
4

Carefully detach the tube from both the sensor and the tub.
5

Flush the tube with warm water and a mild detergent to remove soap scum. A small bottle brush or pipe cleaner can help dislodge stubborn clogs.
6

Inspect the tube for cracks or damage. Replace if necessary.
7

Reattach the tube securely to both the sensor and the tub. Ensure no kinks or obstructions.
8

Restore power to the washer at the breaker panel. Run a test cycle to verify proper water level control. Verify 120V AC at the outlet before starting the washer.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Lock Out/Tag Out (LOTO) procedures must be followed. High voltage components are present. Failure to disconnect power can result in serious injury or death.

Prevention:

Use High-Efficiency (HE) detergent in the correct amount. Periodically run the washer's cleaning cycle with a washing machine cleaner to help prevent soap scum buildup. Avoid using excessive amounts of detergent or fabric softener.

Expert Tip:

Some Admiral washers have a diagnostic mode. Consult the service manual for the correct button sequence (often pressing and holding two buttons simultaneously, such as START/PAUSE and SIGNAL). This mode may allow you to test the water level sensor and other components.

Frequently Asked Questions

•How do I find the service manual for my Admiral washer?

The service manual can often be found online by searching the model number of your washer followed by "service manual." Websites like AppliancePartsPros.com or RepairClinic.com may have it available for download. Also, check the manufacturer's website.

•What if cleaning the tube doesn't fix the problem?

If cleaning the tube doesn't resolve the issue, the water level sensor itself may be faulty. Use a multimeter to test the sensor's resistance or voltage output as described in the service manual. Replace the sensor if it fails these tests. Also, check the wiring harness for damage.

•What is the correct amount of HE detergent to use?

Refer to the detergent manufacturer's instructions. Typically, a small amount (1-2 tablespoons) of HE detergent is sufficient for a normal load. Using too much detergent can lead to excessive suds and residue buildup, contributing to clogs.
