pressure regulator setting. 75
psig recommended. Relieve pressure from
carbonator tank.
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
carbonator 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
flat (low on
carbonation)

Carbonator tank is 100% filled because the

CO

setting for the carbonator tank is 75
psig, max water pressure is 60 psig. If
necessary, install a water pressure
regulating valve.
