4.
Low Flow of Cold Water or Hot Water or Both
Possible Reason
Solution
Too much water pressure. Recommend
40 to 60 psi for the Cube Water
Treatment System to operate properly.
The correct input water pressure is critical to
the performance of the unit to allow
solenoids to open.
Check water pressure at the inlet bulkhead
with a water pressure gauge.
Additional method of verification is to turn
off water to unit and press the dispense
button. Does the solenoid open without
water pressure to the unit? Listen for
solenoid to activate, not button “click”.
Adjust water pressure to 40-60 psi.
Filters blocked
Verify the filters are not partially blocked.
Solenoid Valve
Verify the valves function correctly.
Calcium Build Up in the Hot Tank or the
hot water outlet.
Descale the Hot Tank per instructions
included in this Troubleshooting Section.
5.
Appears as white chunks in water
Possible Reason
Solution
What appears as white chunks in cup is
actually air bubbles caused during filter
change.
Confirm by leaving cup sit overnight. Do
bubbles dissipate?
This will correct itself as the machine is used.
