I have a whirlpool model wtw4815ew0 top load washing machine. Yesterday it stopped spinning. I looked underneath and the belt was still attached. However, the guard was slightly melted down at the smaller end under the drive motor. The drive pulley assembly spins and visually seems to be in good condition. However when I removed the belt the small wheel of the drive motor dropped about an inch and won’t spin. I assume this is a motor problem. Before I buy a new motor, I was hoping to get confirmation of my diagnosis.
Cause 1 Lid Switch Assembly The lid switch assembly prevents the washer from spinning when the lid is open. If the lid switch assembly fails, the washer will not spin. To determine if the lid switch assembly is defective, use a multimeter to test the lid switch for continuity. If the lid switch does not have continuity, replace it. Cause 2 Motor Coupling The motor coupling connects the motor to the washing machine transmission. If the washer is overloaded, the motor coupling will fail in order to protect both the motor and transmission. The motor coupling can also fail due to normal wear. Inspect the motor coupling to determine if it is broken. If the motor coupling is broken, replace it. Cause 3 Drive Belt Inspect the drive belt to determine if it is broken or if it is loose on the pulleys. If the drive belt is broken or loose, replace it.
