This command will only work for brewers with Single Board Electronics installed.
This will display past error history, each line displayed will be a possible clue to the problem that caused the failure. If motor failures have occurred, the status will tell you which motor and what the failure is. Usually it is a sensor problem or a wiring problem that prevents the motor from resetting. If no problems are displayed, then the system can be placed back into cosmac mode for further testing.
Note: You can also relog while in opmode with brewcommand using the Readlog command.
