Booster pump must be used if dynamic water

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)

setting for the carbonator tank is 75 psig,

max water pressure is 60 psig. If necessary,

install a water pressure regulating valve.
