Problem: No Water Dispenses From Cold or Sparkling Valve
IMPORTANT – Do you hear both Inlet Valve and Cold Valve “double-click” when opening and closing?
Inlet Valve must open to allow water into ION. Dispensing Valve then allows water out of appliance.
Therefore, when dispensing water, you will hear two valves clicking open and closed in quick
succession. The clicking indicates the plunger is moving up and down and that the valve has electrical
current. Place your finger on the back of the appliance where Inlet Valve is located and you can feel it
click open and closed. Place your finger on Dispensing valve and you can also hear it click open and
closed. A dead valve (no electrical current) is indicated when you cannot feel the plunger moving
up inside.
