7. Ice not being produced
8. Ice is produced, but does not dispense OR dispenses very slowly
1. No water or Slow Production (Hot/Cold/Ambient)
Check Water Production after
Filtration Bank
Ensure water is pushing past the filters. If flow is slow or stopped
after filters, one or more filters may be plugged and will need to
be replaced. Also check that the booster pump is running. A failed
pump could cause very low flow through the filtration system.
If water gets into the bottom of the system, then the leak stop will
shut off the water supply. Drain any water from the leak stop using
the plug on the back of the unit. The water line AFTER the leak
stop may need to be disconnected then reconnected to break any
vacuum that may have developed in the line.
Check the water pressure into the filter bank and confirm
adequate pressure, should be 50-70psi. Ensure the ¼”-turn valve
just before the filtration system is open.
2. Hot Water Dispense produces water that is not hot
Overload Thermostat Tripped
Locate the Overload Thermostat mounted on the front of the hot
tank. Press the red button to manually reset the thermostat and
return the hot tank power circuit to normal operation.
Damage or disconnection of one of several connections in the hot
tank circuit. Check all wiring, ensure no connections have arced.
