Hotpoint Washer Agitates But Won't Spin: Troubleshooting... | appliancefaults.com

Technical Background:

The washer's Main Control Unit (MCU) controls the motor through relays and triacs. The MCU receives input from the lid switch, water level sensor, and timer to determine the appropriate cycle stage. During the spin cycle, the MCU sends voltage to the motor and drain pump simultaneously. If the lid switch is open or the MCU detects an error, it will prevent the motor from spinning as a safety precaution. Voltage is typically 120V AC.

Symptoms:

The Hotpoint washer fills, agitates normally, and drains the water. However, when it transitions to the spin cycle, the drum does not spin, leaving the towels soaking wet. This necessitates wringing them out by hand. This issue happens even with small loads.

Possible Causes:

Lid switch malfunction
Drive motor or motor capacitor failure
Defective belt (if belt-driven)
Drain pump blockage or failure
Faulty timer or electronic control board (MCU)

Solution:

1

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

Inspect the lid switch for proper function. Use a multimeter to check for continuity when the lid is closed. Replace if necessary.
3

Examine the drive belt (if applicable) for wear or breakage. Replace if needed. A new belt should have the correct tension.
4

Check the drain pump for clogs. Remove any debris blocking the pump impeller. Ensure the pump is receiving 120V AC during the spin cycle.
5

Test the motor capacitor (if applicable). A failed capacitor can prevent the motor from reaching spin speed.
6

Verify the motor windings have correct resistance using a multimeter. Consult the service manual for specifications.
7

If other components test good, suspect a faulty timer or electronic control board (MCU). Replacement may be required.

Safety Warning:

Disconnect power to the appliance at the breaker panel before performing any repairs (Lock Out/Tag Out - LOTO). Capacitors can hold a dangerous electrical charge even after the appliance is unplugged. Use caution when working with electrical components. 120V AC is present in the control panel.

Prevention:

Periodically clean the drain pump filter to prevent clogs. Avoid overloading the washer, as this can strain the motor and belt. Use the appropriate amount of detergent to prevent excessive suds, which can interfere with the spin cycle. Check hoses regularly for leaks or cracks.

Expert Tip:

Many Hotpoint washers have a diagnostic mode. Simultaneously press and hold the Start/Pause and Water Level buttons for 3 seconds to enter diagnostic mode. Consult the service manual for specific error codes and testing procedures.

Frequently Asked Questions

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

The drain pump is typically located behind a lower access panel on the front of the washer. You may need a 1/4-inch nut driver to remove the screws holding the panel in place. Always disconnect power before accessing internal components.

•Where is the lid switch located, and how do I test it?

The lid switch is usually located under the top panel of the washer cabinet, near the lid hinge. Use a multimeter to check for continuity when the lid is closed. If there is no continuity, the switch is likely faulty and needs replacement.

•How can I determine if the motor capacitor is bad?

A visual inspection may reveal a bulging or leaking capacitor. Use a capacitance meter to test the capacitor's microfarad (uF) rating. If the reading is significantly lower than the specified value, the capacitor is likely bad. A non-functioning capacitor usually means a dead or stuttering motor.
