1. Unit is dispensing water intermittently / irregularly
2. Run‐On
3. Low Flow of Water
1. Unit is dispensing water intermittently / irregularly
Possible Reason
Ribbon Connectors are not
fully engaged
Too much water pressure.
Recommend 40‐60 psi for the
WL500 Water Treatment
System to operate properly.
WL500 Manual
DISPENSE TROUBLESHOOTING INDEX
Verify ribbon connectors are properly engaged and fully seated in
front PCB (Printed Circuit Board) to avoid intermittent /
connectivity issues anytime the front Hatch Panel is accessed.
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.

Low Flow of Water – Rated Service Flow is 1.89 Liters (0.5 gallons) per Minute Possible Reason Solution Rated Flow Rate is 1.89 Liters (0.5 gallons) per minute. Check flow Determine Flow of rate by dispensing into a container to measure for one minute and Water measure the amount of water that was dispensed. Feed lines can restrict flow if run long distances from the supply. It Feed Lines too small may be necessary to increase the supply line (e.g., use 3/8” feed line vs. ¼”. Elbows and turns in Minimize elbows and turns in the feed line. the feed line Filters with high pressure drop due to fouling or just by design. Filters Change filters more frequently or go to higher micron size filter for local water conditions. Follow flow path to ensure there are no undiscovered restrictions due Restrictions to debris or malfunctioning valves, including the supply valve at the source. Add a booster pump to the supply line if the feed is slower than Booster Pump needed. WL500 Manual Page 82 Revision 4‐10‐2019 ...
