The Level Sensor has become fouled and no longer senses water
ground, thereby dead‐heading the booster pump on the full tank.
Remove the probe and clean with file or sand paper to provide
proper ground.
The pump is faulty or not producing enough pressure to fill the
carbonator. Check pump to ensure output pressure is above 80 psi.
If not, replace pump.
Water supply has been shut
off
Turn water supply on
Too much water pressure.
Recommend 40‐60 psi for
the
WL500 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 just the dispense button
“click”)
Adjust water pressure to 40‐60 psi.
The Filters have become
fouled and plugged,
thereby starving the
booster pump of make‐up
water
Change Filters
The CO
2
gas pressure is
above 45 psi, and the
booster pump has dead‐
headed and cannot fill the
Sparkling Chamber.
Turn CO
2
gas pressure to 45 psi, verify with pressure regulator.
The Sparkling Water Level
Sensor has faulted and is
not properly signaling the
PCB to turn off the water
injection pump once water
fills to the probe level in the
tank. No Water Supply
error message will display
and the pump will shut
down after 10 minutes to
prevent damage.
Remove the probe and clean. Disconnect from power, shut off CO
2
gas to
isolate Sparkling Chamber and relieve pressure in tank through the
Pressure Relief Valve before removing the probe.
