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

Technical Background:

The Motor Control Unit (MCU) controls the drain pump and the motor for the spin cycle. The MCU relies on feedback from the lid switch/door lock to initiate and maintain the spin. Proper voltage pathways are required for all components to function correctly. The drain pump needs 120V AC to operate, and the motor also needs 120V AC during spin.

Symptoms:

US homeowner reports that clothes are still dripping wet after the Hotpoint washer completes its spin cycle, even after a prior repair attempt.

Possible Causes:

Clogged drain pump filter
Defective drain pump
Blocked drain hose
Worn or broken drive belt (if applicable)
Faulty lid switch or door lock assembly
Malfunctioning motor control unit (MCU)

Solution:

1

Unplug the washer from the 120V AC outlet. Lock Out/Tag Out (LOTO) procedure is required.
2

Inspect the drain pump filter for debris. It's usually located at the front, bottom right behind a small access panel. Clean thoroughly.
3

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

Test the drain pump. Disconnect the wires to the pump and using a multimeter, check for continuity. No continuity indicates a failed pump.
5

Examine the lid switch or door lock assembly. A faulty switch will prevent the washer from spinning. Use a multimeter to test for continuity when the lid is closed/locked.
6

If the above steps fail, the MCU may be faulty. Check the voltage at the motor terminals with a multimeter during the spin cycle. Expect approximately 120V AC. No voltage, and the MCU is suspect.
7

If drive belt is present, inspect for damage and replace. Usually requires a 5/16-inch socket to remove the rear access panel.

Safety Warning:

Always disconnect power (120V AC) to the washer before performing any repairs. Follow Lock Out/Tag Out (LOTO) procedures to prevent accidental energizing. Capacitors may hold a charge even after the unit is unplugged. Use extreme caution when working around electrical components.

Prevention:

Regularly clean the drain pump filter (every 3 months). Avoid overloading the washer. Use the correct amount of HE detergent. Annually inspect the drain hose for wear.

Expert Tip:

Enter the service mode by pressing and holding the start button for 3 seconds, then simultaneously pressing the power button and start button. This may allow you to run diagnostic tests on the individual components.

Frequently Asked Questions

•What is the proper resistance reading for the drain pump?

The drain pump resistance should typically be between 5 and 15 ohms. Refer to the service manual for your specific model for the exact range.

•How do I access the MCU on this Hotpoint washer?

The MCU is usually located behind the control panel. You'll need to remove the control panel screws (usually using a 1/4-inch nut driver) and carefully detach the panel to access the MCU.

•What are the common failure modes of the lid switch?

The lid switch can fail mechanically (broken latch) or electrically (corroded contacts or open circuit). Use a multimeter to test for continuity with the lid closed/locked.
