12. No Water is Dispensing from One Side – Cold or Hot
Possible Reason Solution
Too much water pressure.
Recommend 2.7 to 4 bar for
the
WL2FW Water Treatment
System
to operate properly.
Verify water pressure at the Inlet Bulkhead with a Pressure
Regulator.
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 the
Dispense Button “click”.
Adjust water pressure to 2.7-4bar. The correct input water pressure
is critical to the performance of the unit to allow solenoids to open.
PCB
Switch the hot and cold wires on PCB (red and blue connections).
If water now dispenses from the opposite side, this is an indication
that there is a PCB problem.
Replace PCB
Solenoid
If both the Water Pressure and PCB have been ruled out, then it is
the Solenoid.
Replace Solenoid.
See “ Green Flashing Light”
Fault Code Section of this
Manual
Indicates the Firewall UV system is not detecting adequate dose of
UV to ensure safe water.
13. Cold Water Dispenses from Faucet and Vent Outlet Simultaneously
Possible Reason Solution
Improper tubing attachment
from the Cold Tank to Faucet
or vice versa
Verify tubing is connected properly from Cold Tank Outlets to
correct Faucet attachments.
Scale has formed inside Cold
Tank outlet tube.
Remove Cold Water Outlet Tube from Cold Tank to Faucet. Pour
some scale remover into Cold Tank.
Expansion chamber in Cold
Tank is not sealed properly.
Replace Cold Tank.
