My whirlpool cabrio washer model no.wtw5500xw when i go to start it on sensing i always have trouble it won't spin our if it spins once or twice then it stops and stays humming loud some times. I'll get to work on bulky items or on delicate some times it works on drain & spin or rinse & spin but it always just humming continuously. One day oit smelled like burn plastic or something and in the middle of a wash out will click and start humming what could be the problem?
You may have bad capacitor, motor failing, transmission issue, or another issue that causes the motor to hum. Have you opened the machine up and checked to see if there is any obvious sign of the issue?
