Water System Errors

There are three system errors that can be detected by the microprocessor. These errors are:

1.Water Fill Error (Er1) – the water full detection has failed, and the fill valve has been on for at least 5 minutes.

2.Thermistor Error (Er2) – the Thermistor is detected either open, shorted OR the water is boiling.

3.Heater Error (Er3) – the heater has been on for 3 minutes, but no rise in water temperature was detected.

If any of these errors are detected, the unit will shut off all water fill and heat related functions. Brewing is disabled, but grinding is still allowed. The display will show the error when the unit is idle. To clear any error, the user can hold in the UP key for 5 seconds, reset power to the unit or enter field test mode.
