Trouble power up the unit

[Craig]

When I push in the on button, I can get it to stay on, but only after a couple of tries. At this point, however, the motor button will not stay in regardless of how many times I try to put it in.

The issue is likely due a gap between the switch board and the buttons mounted to the User Interface box. Tightening the (4) ¼” nuts that secure the switch board to the inside of the box a ½ turn will resolve the problem.
