WaterLogic PUREZZA WL2FL FIREWALL Manual page 55

1. Irregular / Intermittent Dispensing from One Side
Possible Reason
Too much water pressure.
Recommend 2.5 to 3 bar for
the WL2FL Water Treatment
System to operate properly.
Loose or bad connection on
the Front Dispensing PCGB or
Solenoid Connector
Solenoid
Dispensing button is broken on
PCB
2. Hot Water Intermittently Forced Out Through the Faucet, or a Dual Stream Outof
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.
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.
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.
