Solution 1 - Check the fuse on the control board.
Problem 2 - The buttons on the keypad won’t respond, but the
manual override does.
The control board stores the shot volume settings and controls the auto-fill circuit. The control board
uses a 6.3 amp fuse to protect it against damage due to faulty electrical/electronic components. If
this fuse trips, it causes the machine’s automatic functions to stop.
Important! Before proceeding with solution 1, the following steps must be accomplished.
1. Turn the machine off.
2. Disconnect the power cord from the wall outlet.
1. Remove the ma-
chines left-side panel
by removing one phil-
lips-head screw.
2. Remove the
control board
bracket and pull
the unit from the
side of the ma-
chine.
3. Remove the
three phillips-head
screws and lift off
the control box
cover.
4. Locate the fuse
and visually inspect
for burn marks or
damage.
Replace if discolored
or damaged.
5. If the fuse appears func-
tional, carefully remove it
from the board.
6. Ohm out the fuse us-
ing a multi-meter.
7. Replace the fuse if a
reading greater than zero
ohms is registered.
Replace only with a fuse of
the same size and rating.
Return the machine to ser-
vice.
