6. Hot Water Coming out of Faucet Vent Hole
Possible Reason Solution
Too much water pressure.
Recommend 2.7 to 4 bar for the
WL2FW Water Treatment System to
operate properly.
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 2.7-4bar.
Improper tubing attachment from
the tank to faucet or vice versa.
Verify tubing is connected properly from tank outlets to
correct faucet attachments.
Hot Tank outlet hole is scaled over.
Inspect and Descale Tank as needed.
See Hot Tank Descaling Instructions that are included
further below in this Troubleshooting Section.
See instructional video on the Partner Area of the
Waterlogic.com website for more information.
Expansion chamber is not sealed
properly.
Replace the Hot Tank.
