Water valve will not open
Check electrical connection to water valve.
Check resistance of coil (should be 9 ohms).
Check for voltage at coil when brand button is
depressed.

Carbonator tank is empty, because tank was
emptied while power was applied to unit. 5
minute time-out of carbonator pump/motor
occurred, and carbonator pump is locked off.
Unplug the unit and reconnect the unit. Main
control board will reset, ice agitation will occur,
and carbonator tank will refill to normal level.
Note that this can occur while the water filter
system is serviced or water supply is shutoff. If
drinks are drawn from the dispenser while
water pressure is shutoff, the carbonator pump
starts and runs continuously, then shuts off on
the 5 minute timeout.
1) low water pressure switch deactivates car-
bonator pump, 2) after 5 minutes reset and
retry carbonator pump. If water supply is
restored, the 5 minute timeout will not occur.
Repeat reset a second time, but on a third
time, then lockout carbonator pump, which will
generate a service call.
Carbonated drinks are

install a water pressure regulating valve.
Low water pressure
Could be caused by excessively long runs
(over 40 ft.) of 3/8” water supply line.
Increase line size to 1/2”

Carbonator Troubleshooting
Symptom Cause Remedy
Carbonator pump does
not start to fill tank Power cord for the carbonator pump motor is
not connected.
Carbonator pump is powered off the main con-
trol board inside the electrical box of the unit.
Check that the umbilical cord is connected
from the unit to the pump motor terminal box.
