1. Irregular / Intermittent Dispensing
Possible Reason Solution
Too much water pressure.
Recommend 40 to 60 psi for
WL400 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.
Mineral deposits on the
expansion slot inside the Hot
Tank vent chamber which
blocks the normal path of
water to expand. Descale Hot Tank.
See Hot Tank Descaling Instructions that are included
further below in this Troubleshooting Section.
