It sounds like a bearing OR the motor may have locked up on you. Open the top and try to turn the tub clockwise by hand.
Ok. Hold the top open and have someone push the start button while you CAREFULLY give the tub a turn. Let me know if it takes off tumbling.
It barely moves when I push the button and try to turn it
You telling me it turns by hand rules out the tumbler bearings so that would mean that your motor has failed and will need to be replaced.
OK, how do we access that if we decide to replace it?
