TROUBLESHOOTING
Irregular / Intermittent Dispensing
Possible Reason
Solution
Too much water pressure.
Recommend 40 to 60 psi for
WL400
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.
Dispensing button is broken on
PCB
Check PCB for loose or damaged button. Replace PCB as
necessary.
