FAULT CODES and TROUBLESHOOTING
Indication Action
The display indicates: “Change Filter”
Replace the filter. Either the gallons
setting or the filter timer (months) setting
has expired. Reset the machine once
filters are replaced.
The display indicates: “Drip Tray Full”
Continuous Audible Alarm will Sound
Empty and clean the drip tray. Make sure
the metal clips on the tray are clean.
The display indicates: “Hot Fault”
Indicates a hot tank sensor fault. Check to
make sure the sensor is plugged in to the
main PCB properly.
The display indicates: “Cold Fault”
Indicates a cold tank sensor fault. Check to
make sure the sensor is plugged in to the
main PCB properly.
The display indicates: “No Water Supply”
Check to make sure water is available to
the unit and Filter Timer is active instead
of Filter Counter. See Note Below
The display indicates: “UV Fault”
Audible Alarm will sound for 15 seconds
The UV lamp has failed. Replace lamp.
Check UV Sensor Indicator function
NOTE: “NO WATER SUPPLY” fault appears when the booster pump runs for 10 minutes and
there is not a signal from the level sensor to shut off the pump. This is a safety feature to
prevent the pump from being damaged. When operating properly, it should take about 1-1/2
minutes for the pump to inject enough water to completely fill the 1 liter sparkling chamber.
Typical reasons for generating the NO WATER SUPPLY fault in the display are:
1. The water supply has been shut off.
2. The filters have become fouled and plugged, thereby starving the booster pump of
make-up water. Change the filters.
3. The CO
2
gas pressure is above 45 psi, and the booster pump has dead-headed and
cannot fill the sparkling chamber.
4. The Level Sensor has become fouled and no longer senses water, thereby dead-heading
the booster pump on the full tank. Remove the probe and clean. Disconnect from
power, shut off CO2 gas to isolate sparkling chamber and relieve pressure in tank
through the Pressure Relief Valve before removing the probe.
5. The Filter Counter is enabled and there is no signal. Enable the Filter Timer.
CAUTION! RIBBON CONNECTORS MUST BE FULLY ENGAGED . Ensure ribbon
connectors are properly engaged and fully seated in front PCB (Printed Circuit Board) to
avoid intermittent/connectivity issues any time the front hatch panel is accessed.
