DISPENSING TROUBLESHOOTING
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 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.
Remove Dispensing PC and inspect switches.
Replace Dispensing ay PCB if switches appear broken. (Part
Number EN‐6130 – WLCP PN 20‐0040)
Inspect Solenoid for debris and clean out as needed.
Dirt or Foreign material is filling the gap around the push‐buttons.
Inspect the push buttons and clean surrounding area. Inspect
faucet assembly inside the unit and clean as necessary.
