3.
Low Flow of Water
1.
Unit is dispensing water intermittently / irregularly
Possible Reason
Solution
Ribbon Connectors are not
fully engaged
Verify ribbon connectors are properly engaged and fully seated in
front PCB (Printed Circuit Board) to avoid intermittent /
connectivity issues anytime the front Hatch Panel is accessed.
Too much water pressure.
Recommend 40‐60 psi for the
WL500 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 just the
dispense button “click”)
Adjust water pressure to 40‐60 psi.
