Error Message
With the G3/Gold Cup Series brewers, there are three error messages that can appear on the screen to advise the user of a malfunction. If one
of these error messages appear, the brewer will lock up and stop functioning until the error is corrected. An error message will occur under the
following conditions:
1. Water level ll error or overow. This error message occurs when the inlet valve solenoid has been on for more than
10 minutes. This error message also occurs when the valve is relling the tank during a brew cycle for more than 1½
minutes.
2. Water temperature control system error. An open probe or a break in the temperature control circuit is detected.
3. This error message indicates there is an overheating problem. The sensor is reading that temperature in the heating
tank has risen above 210ºF.
Usually the screen will display a service call phone
number. Once a malfunction is corrected, the error
message must be cleared. To reset the control panel
and return to normal operation, press the  button for
5 seconds.
