Electronics Troubleshooting
The electronic boards on the Bevariety™ dispenser have only a few connections and are they
are relatively easy to service; however, you have little room to work with at the top of the
beverage dispenser so it is best to remove the board from its standoff brackets if any
connections need to be made.
Note:
Handle the boards with care as they damage easily.
