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.
Open the water supply valve.
Check electrical outlet connection, or for blown circuit breaker.
Turn Red Heater & Compressor Switch on.
I = ON
Replace the 10 Amp Fuse as needed.
Remove the Top Cover and Front Panel. Tip the unit slightly to
drain, dry Bottom Tray completely.
Turn power off; unplug the WL2FL Water Treatment System and
visually inspect Solenoid connections into the Display PCB. Verify
the soldering points on connections are secure into the board.
Remove the PCB to inspect the front of the board.
Replace filters as needed.
