all of the machine’s components are controlled or activated by the control board you can activate and test compo-
nents individually from the user interface. This allows you to listen to solenoid valves opening, observing the ow of
water or test to see if a component is receiving voltage using a meter.
The Service Tools option is located in Level 2 of the programming. Enter level 2 programming by pressing and hold-
ing the right hidden switch for 5 seconds. Use the right hidden switch to scroll to the Service Tools Screen.
