9.
No Cold Water Available
Possible Reason
Solution
Too much water pressure.
Recommend 40 to 60 psi for
the
WL100 Water Treatment
System
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 to mistaken for the button “click”.
Adjust water pressure to 40‐60 psi.
The correct input water
pressure is critical to the performance of the unit to allow
Solenoids to open.
