WaterLogic WL380 Troubleshooting Manual page 2

1. Irregular / Intermittent Dispensing from One Side
Possible Reason
Too much water pressure.
Recommend 40 to 60 psi for
the WL380 Water Treatment
System to operate properly.
Loose or bad connection on
the Front Dispensing PCB or
Solenoid Connector
Solenoid
Dispensing button is broken on
PCB
2. Hot Water Intermittently Forced Out Through the Faucet, or a Dual Stream Out of
the Faucet
Possible Reason
Mineral deposits on the
expansion slot inside the hot
tank vent chamber which
blocks the normal path of
water to expand.
WL380 Manual
Check water pressure at the inlet bulkhead with an accurate
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".
REGULATE input Water Pressure to 40‐60 psi.
Check that they are connected properly and tightened.
If both the Water Pressure and PCB have been ruled out, then it is
the Solenoid.
Replace Solenoid.
Check PCB for loose or damaged button. Replace PCB as
necessary.
