Manual
Page 70 - Revision: 7-27-2022
Hot and Cold Solenoid
connections into the Display
PCB are loose.
Turn power off; unplug the unit and visually inspect solenoid
connections into the Display PCB. Verify the soldering points
on connections are secure into the board. Remove the PCB
to inspect the front of the board.
Exhausted Filter
Replace filters as needed.
3.
Steady Drip Out of Faucet
Possible Reason
Solution
Debris in Solenoid
Inspect Solenoid for debris and clean out as needed.
4.
Irregular / Intermittent Dispensing
Possible Reason
Solution
Too much water pressure.
Recommend 40 to 60 psi for
WL3 FX
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 button “click”.
Adjust water pressure to 40-60 psi.
Loose or bad connection on
the Front Dispensing PCB or
Solenoid Connector
Check that they are connected properly and tightened.
Solenoid
If both the Water Pressure and PCB have been ruled out,
then it is the Solenoid. Replace Solenoid.
Dispensing button is broken on
PCB
Check PCB for loose or damaged button. Replace PCB as
necessary.
5.
Small Amount of Water Periodically Dispenses from Faucet Automatically
Possible Reason
Solution
Cold or Hot Water Solenoid
Valve malfunction`
Inspect valve components for proper function. Replace as
necessary.
Obstruction in Solenoid
housing is preventing proper
sealing of component
Pre-determine whether water being dispensed is Hot / Cold.
Isolate the water supply; push the DISPENSE button to release the
line pressure, and remove the coil affixed to the Solenoid stem.
Remove the stem from the solenoid housing and allow water from
the tank to flush out the contaminate(s).
