I actually fired up my Maytag A806 since it had been sitting for a few months but wasn’t agitating even though the motor was running, a short while later it started to squeal. Stopped the machine, laid the drain hose down to drain the water, removed the front panel, propped the machine up on a paint bucket, moved the drive belt by hand and that fixed that. The belt had simply developed a flat spot on the motor and just wasn’t wanting to move. Simply by rocking and moving the belt around corrected that issue.
