I have a Whirlpool WTW5500SQ2 that recently started making a noise on the spin cycle. The noise goes away when I press on the top of the machine. The machine is level both directions when measuring the top of the unit, but it also started walking a bit on fast spins. Below is a recording I made with two dryer balls spinning to enhance the noise. You can hear the noise stop when I press the top of the machine. Thanks for any help.
