AFTER MAINTENANCE ACTIONS
Reconnect the incoming water (if disconnected) and
turn on. Then restore power to the unit. Run the unit for at
least 10 minutes, running an empty rack through the machine
to ensure that it is carried all of the way through. If you hear
any grinding sounds while the motor is running, immediately
shut off the unit and secure power and water. There is a seri-
ous problem that must be addressed. If any problems arise
you can contact Jackson Technical Service.
