TROUBLESHOOTING
No Water is Dispensing from One Side – Cold or Hot
Possible Reason
Solution
Too much water pressure.
Recommend 40 to 60 psi for
WL400
to operate properly.
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.
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

Indicates the Firewall UV system is not detecting adequate
dose of UV to ensure safe water.
