The drain pump is coupled to a 120 VAC, 60 Hz, 85 watt motor. The pump motor has an approximate resistance value of 12 Ω.
The main control monitors the pump for proper operation. If no current is detected, or current detected is stable, exhibiting no change during pump out, the control will initiate a field service error code.
Note: If a wash cycle has started and the customer stops the washer by holding the Start/Pause button for 3 seconds, the pump will not drain any water from the tub. The washer will go through a spin algorithm to de-energize the mode shifter and shut down. The water stays in the tub.
The adaptive drain consists of the board sampling the drain pump current during pump out. The control will then turn off the drain pump during the spin cycle. The control will periodically turn the pump back on and resample the pump current draw. If the control does not sense the higher sampled current draw, indicating pumped water, the control will turn off the drain pump.
This feature has benefits for suds lock control and less energy consumption.
Do NOT replace the drain pump or control for this symptom!
It is normal operation (on some models), for the drain pump to turn off in the spin cycle.
The lid switch assembly consists of 2 magnetically operated switches, enclosed in a plastic housing. One switch controls AC voltage and the other DC voltage.
The lid switch assembly is located under the cover/ lid assembly at the right front corner of the lid recess. The switch assembly is held to the underside of the cover by a latch plate and a Phillips-head screw.
The switch assembly is a safety feature that prevents washing or spinning when the lid is open. Both switches are closed by a magnet attached to the lid. When the lid is shut, the magnet will cause both switches to close, allowing normal functions to occur. When the lid is opened, both switches will open, which will prevent washing or spinning.
If the lid switch:
• Is closed, it will provide 120 VAC to the inverter/ motor assembly at pin 6 of the C2 connector.
• Is open, agitation and spin will not occur, the control will beep and display lid to signal the lid should be closed.
• Was opened during a cycle, left open and the timer finished the cycle, when the lid is closed again, the inverter completes a spin algorithm to ensure the mode shifter is de-energized.
• Is open, the ATC will be disabled during the time the lid is open.
• Opens during agitation, the control will keep the mode shifter energized. When the lid switch closes while still in agitation, the washer will resume agitation.
• Opens during the execution of the mode shifter agitate program, the control will stop the agitate program and drop the mode shifter voltage to 0 VDC. When the lid switch is closed again, the control will run the mode shifter spin program and then re-run the agitate program from the beginning.
• Opens during the mode shifter spin program, the control will stop the spin program. When the lid is closed again, the control will run the spin program from the beginning.
• Lid switch openings are not retained in memory if power is interrupted.
• As a safety measure, the inverter control monitors lid openings by recording motor run sequences. If the control runs 4 continuous agitation/spin cycles (usually 2 complete wash cycles) WITHOUT seeing the lid switch open, it will shut down the motor and initiate a lid switch error code. This error will prevent the motor from operating until the problem is repaired.
To access the lid switch assembly, it is necessary to remove the cover/lid assembly. (See Cover/Lid Assembly.) To release the switch assembly from the cover/lid assembly requires opening the lid and pressing the lock tabs on the latch plate outward and removing the Phillips-head screw. A plastic compression tab attaches the switch wire harness to the cover/lid assembly. The switch assembly can then be removed from the cover/lid.

If your whirlpool washer has stopped spinning and you have checked the motor couple only to find it’s ok then you may need to replace the clutch.
This video will show you step by step how to replace agitator assembly, part # 3946501
Part Number: AP3138838 includes 4 agitator dogs, a medium length cam, a cap seal, a washer for the agitator bolt and a thrust washer. Is your upper agitator not working properly? Get this kit. Whirlpool recommends using a small amount of grease with this kit (if no grease is present on the old thrust washer). For the Whirlpool agitator grease order AP3098553. For the long cam order AP3094520. For the short cam order AP3094543.
Whirlpool brands include Whirlpool, Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and others. Whirlpool also makes various appliance models for Sears / Kenmore.
