Amana Washer: Clothes Still Wet After Spin Cycle -... | appliancefaults.com

Technical Background:

MCU logic and voltage paths: The Motor Control Unit (MCU) controls the motor's operation during the spin cycle. The MCU relies on feedback from sensors, like the lid switch and water level sensor, to initiate and maintain the high-speed spin. Voltage paths within the MCU must be intact to supply power to the motor and other components. Any interruption in these voltage paths or incorrect signals from the sensors can prevent the spin cycle from engaging.

Symptoms:

US homeowner observations: The Amana washer completes its cycle, but the clothes are still soaking wet, indicating a failure in the spin cycle's water extraction.

Possible Causes:

Clogged drain pump filter or drain hose.
Worn or broken drive belt.
Defective lid switch or lid lock assembly.
Malfunctioning motor control unit (MCU).
Faulty water level pressure switch.
Over sudsing from using too much detergent.

Solution:

1

Unplug the washer from the 120V AC outlet and turn off the water supply.
2

Inspect and clean the drain pump filter. Usually located behind a small access panel at the bottom front of the washer. Remove any debris.
3

Check the drain hose for kinks or clogs. Disconnect the hose from the drainpipe and flush it out with water.
4

Examine the drive belt for wear, cracks, or breaks. Replace the belt if necessary. Common tools needed: 5/16-inch socket and nut driver.
5

Test the lid switch or lid lock assembly for continuity using a multimeter. A closed circuit should exist when the lid is closed. Replace if defective. Check for 120V AC at the lid switch when activated.
6

Verify proper water level pressure switch operation. You can often test the continuity with a multimeter; look for a change in state (open to closed or vice-versa) as you apply pressure to the switch's inlet tube.
7

Run a clean washer cycle with no clothes and minimal detergent to remove excess suds.

Safety Warning:

LOTO and high voltage warning: Always disconnect the power supply to the washer by unplugging it from the outlet before performing any repairs. High voltage is present inside the appliance. Follow Lock-Out/Tag-Out (LOTO) procedures to ensure the machine is de-energized before working on it.

Prevention:

Specific maintenance: Regularly clean the drain pump filter (every 3 months). Use the correct amount of HE (High Efficiency) detergent. Periodically inspect the drain hose for kinks or obstructions. Avoid overloading the washer.

Expert Tip:

Trade secret or service mode sequence: Some Amana washers have a diagnostic mode that allows you to retrieve error codes and run component tests. Consult the service manual for the specific sequence for your model. This often involves pressing a combination of buttons in a specific order (e.g. Power-Select-Start).

Frequently Asked Questions

•How do I access the diagnostic mode on my Amana washer if I don't have the service manual?

While the exact sequence varies by model, a common method involves pressing and holding the Start button, then pressing the Power button twice in quick succession, followed by releasing the Start button. Check online forums or appliance repair websites for model-specific instructions.

•What type of drive belt does my Amana washer need?

The drive belt type and size depend on your specific model number. Refer to your washer's parts diagram (usually available online by searching your model number) to identify the correct replacement belt.

•How much does a new motor control unit (MCU) cost, and is it difficult to replace?

The cost of an MCU can vary widely, from $100 to $300 or more, depending on the model. Replacement involves disconnecting wiring harnesses and mounting screws. If you're comfortable with basic electrical work, it's a manageable DIY project; otherwise, consider hiring a professional.
