I'm installing a new Bosch dishwasher, and it has a screw at the bottom of the front toe kick area to adjust the rear leveling leg, but when I turn the screw the mechanism that turns the leg seems to be stripped. The screw turns but then there is a snapping sound, and the leg does not move. I did have it adjusted properly but need to pull out the machine to fix a small leak, but now I can't pull it out because the leveling leg can't be lowered, and the insulation is to tight against the underside of the counter. Any ideas?
