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 rate by dispensing into a container to measure Determine Flow of Water for one minute. Measure the amount of water that has been dispensed. Feed lines can restrict flow if run long distances from the Feed Lines too Small supply. It may be necessary to increase the supply line (e.g., use 3/8” feed line vs. ¼”. Elbows and turns in the feed line Minimize elbows and turns in the feed line. Filters with high pressure drop due to fouling or just by Filters design. 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 restrictions due 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 Booster Pump than needed. WL380 Manual Page 45 ‐ Revision: 2‐5‐2018 ...

Expansion Chamber in the top of the tank except for WL270 (GF) units. The Vent Chamber allows for expansion of the water when it is heated. The chambers are separated by a welded‐in tank baffle. Water always flows into the bottom of the Hot Tank and out the top to the Faucet. The Hot Tank Outlet Tube has a Restrictor in its base. This ensures the reservoir is always full by allowing more water in than out. There is a small hole in the side of the Hot Tank Outlet Tube that allows air and water to pass into the Vent Chamber as it is heated. Water in the Vent Chamber is suctioned back through the Outlet Tube vent hole when water is dispensed. Expansion of water as it is heated in the Reservoir will push the water out the faucet when the outlet tube vent hole becomes plugged with debris or scale. The small Outlet Vent Hole is susceptible to scale build up and is a key indicator that descaling is required. It is critical to descale the Hot Tank through the vent line and outlet line on a regular basis to prevent this problem. Descaling through the inlet and/or outlet lines only will not clean the vent chamber and outlet vent hole properly. WL380 Manual Page 46 ‐ Revision: 2‐5‐2018 ...

12. No Water is Dispensing from One Side – Cold or Hot Possible Reason Solution Verify water pressure at the Inlet Bulkhead with a Pressure Regulator. Too much water pressure. Additional method of verification is to turn off water to unit and Recommend 40 to 60 psi for press the Dispense Button. Does the Solenoid open without water the WL380 Water Treatment pressure to the unit? Listen for solenoid to activate, not the System to operate properly. Dispense Button “click”. Adjust water pressure to 40‐60 psi. Switch the hot and cold wires on PCB (red and blue connections). If water now dispenses from the opposite side, this is an indication PCB that there is a PCB problem. Replace PCB If both the Water Pressure and PCB have been ruled out, then it is the Solenoid.

5. Allow descaling solution to remain in the Hot Tank for 15 minutes (length of time may vary depending on water conditions). 6. Place a pitcher, catch basin or other container under the faucet of the WL380 Water Treatment System. 7. Flush the Hot Tank until water runs clear. 8. Once clear Water dispenses from the faucet the Hot Tank has been descaled. Always ensure the WL380 Water Treatment System is performing to the customer’s satisfaction. WARNING! HOT WATER. HOT WATER. Unit produces Hot Water in excess of 80 C (175 F). Water above 52 C (125 F) can cause severe burns or scalding. Keep unauthorized people and children away from the unit to avoid accidental dispensing of hot water. CAUTION! MUST REPLACE HOT TANK 3‐5 YEARS DEPENDING ON USAGE. The Hot Tank and its controls must be replaced a minimum of every three to five years to ensure efficient and dependable operation. WARNING! REINSTALL ALL PANELS AND COVERS.
