Water System Errors
There are four system errors that can be detected by the
microprocessor. These errors are:
Er1
Water Fill Error – the water full detection has
failed, and the fill valve has been on for at least 5
minutes.
Er2
or
Er3
Thermistor Error – the Thermistor is
detected either open, shorted OR the water is
boiling.
Er4
Heater Error – 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.
