Low water pressure
© 2005-2009, IMI Cornelius Inc.
Poor ice quality due to water quality or
ice maker problems
No 24VAC to valves
No CO pressure
2
Valve brix requires adjustment
Carbonator is not operating
No CO in carbonator
2
City water pressure supply low or
inconsistent
CO pressure in carbonator tank is too
2
high.
Water valve will not open
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.
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.
CO is out
2
Carbonator tank is 100% filled because
the city water pressure exceeds the
carbonator tank CO pressure regulator
2
setting.
Could be caused by excessively long
runs (over 40 ft.) of 3/8" water supply
line.
Low water pressure
Plugged water filter.
Water booster bladder has burst
Correct water quality or repair ice maker
Restore 24 VAC to valves
Restore CO
Adjust valve brix
Repair carbonator
Restore CO
Booster pump must be used if dynamic
water pressure drops below 40 psig.
Check CO
75 psig recommended. Relieve
pressure from carbonator tank.
Check electrical connection to water
valve. Check resistance of coil (should
be 9 ohms). Check for voltage at coil
when brand button is depressed.
Unplug the unit and reconnect the unit.
Main control board will reset, ice
agitation will occur, and carbonator tank
will refill to normal level.
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.
Replace CO
CO setting for the carbonator tank is
2
75 psig, max water pressure is 60 psig.
If necessary, install a water pressure
regulating valve.
Increase line size to 1/2"
Add water pressure booster pump
Change water filter
Replace water booster tank/bladder
