Dispenses Hot and Cold Water at the Same Time
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.
Hot or Cold Solenoid is stuck
open.
Remove Top Cover.
Check Hot Solenoid: Dispense cold water and visually inspect
tubing for water flow from both tanks.
Check Cold Solenoid: Disconnect elbow from outlet of cold
Solenoid. Select hot water and dispense (quickly releasing
dispensing button to avoid much water coming out of cold
Solenoid.
Replace Solenoid as necessary.
