3.Diagnostics – Error Codes:

The B3000 contains real-time error detection. There are a number of operational errors that, if encountered, will disable the brewer, produce an error code onto the LCD display, and will also flash all 4 buttons on the front panel LED’s to attract attention. The power may be cycled to attempt to clear the error, but if it occurs again, the same message will be displayed.

Below is a summary of all errors, their meanings and the menu messages.
