  • Page 12: Troubleshooting Chart

    Troubleshooting Chart Problem: Water Dispenses from Cold or Sparkling Valve, but Water not Cold Cause Action 1. ION has been in SleepMode (with compressor off) for 1. Allow ice to build over 3-4 hour time period. Optionally, weekend or long holiday. program SleepMode to be OFF (Ice Bank to be maintained 24 hours per day).
  • Page 13 Troubleshooting Guide 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.
  • Page 14 Troubleshooting Guide Problem: Water dispenses from Hot Valve, but water not Hot Cause Action 1. ON/OFF switch at back of ION 1. Turn to ON position. 2. Wiring and connectors at Control Board 2. Check for continuity (not voltage) through the hot tank connector and wiring harness at Control Board (with ION unplugged and Switch in ON position).
  • Page 15 Troubleshooting Guide Problem: No Water dispenses from Hot Valve Cause Action 1. Are customers pressing BOTH Hot and Safety button 1. Refer to Instruction Label inside filter door of appliance at same time? and notify customer. 2. Do you hear both Inlet and Dispensing Valve clicking open and closed?.
  • Page 16 Troubleshooting Guide Problem: Low or No Water Flow IMPORTANT – Keep in mind that inside the ION, there is a 1 micron carbon filter and 23’ of 1/4” tubing (the Water Coil is 20’ in length). Plan ahead for adequate water pressure and flow rate into the ION. Cause Action 1.
  • Page 17 Troubleshooting Guide Problem: Blue LED not ON IMPORTANT – SleepMode is an energy saving feature that is programmed into the Control Board. A photo sensor behind the LED3 on Front Panel allows software to turn the compressor OFF when room is dark. Check the location carefully…...
  • Page 18 Troubleshooting Guide Problem: Blinking RED lights (both together, not alternating) IMPORTANT – Ice Bank automatically fills by using a Level Sensor. To prevent endless water flow from failed Level Sensor, software only allows the Ice Bank to fill for 5 minutes on STARTUP. Once the ION has passed STARTUP, the Ice Bank is limited to a fill time of 2 minutes.
  • Page 19 Troubleshooting Guide Problem: Steady Orange lights (never goes to blinking Orange lights) IMPORTANT – on software rev level prior to L (Sept. 2007), a hot or cold sensor unplugged (or not completely connected) will cause this condition. During shipping, the sensor connections can become unstable and may require careful removal (straight back) and reinsertion onto the Control Board (see wiring diagram).
  • Page 20 Troubleshooting Guide Problem: Water Leak IMPORTANT – the ION uses an Inlet Valve to allow water to enter the appliance. Only when the customer presses Touch Panel to dispense water – or when Ice Bank automatically fills – does the Inlet Valve open to allow water to enter the appliance.
  • Page 21 Troubleshooting Guide Problem: Steady RED lights – Filter Change required. When pressing Filter Reset button, does not reset RED lights to GREEN. IMPORTANT – When changing filters, ALWAYS reset the filter monitor (time and gallons) to zero by pressing the Filter Reset button until you hear a beep (about 6 seconds).
