14. Small Amount of Water Periodically Dispenses from Faucet Automatically
Possible Reason
Too much water pressure.
Recommend 2.5 to 3 bar for
the WL2FL Water Treatment
System to operate properly.
Cold or Hot Water solenoid
valve malfunction
Obstruction in solenoid
housing is preventing proper
sealing of component.
15. Dispense Buttons Stick
Possible Reason
Dirt or Foreign material is
filling the gap around the
Dispense Buttons.
WL2FL Manual
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 button
"click".
Adjust water pressure to 2.5-3bar.
Inspect valve components for proper function. Replace as
necessary.
Pre-determine whether water being dispensed is hot or 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 contaminant(s).
Inspect the Dispense Buttons and clean surrounding area. Inspect
Faucet Assembly inside the WL2FL Water Treatment System and
clean as necessary.
