System messages
The Revolution control system constantly monitors internal operating conditions. If the system detects a problem, it will
produce an error (“ER”) message. If the display shows an ER message, first unplug the unit and then plug it back in. This
will usually reset the electronics, and the unit will begin operating normally. If the error message reappears, refer to the
explanation and solution shown below. If this still does not fix the problem, contact your local authorized service center or
call the Dri-Eaz Service Department at 800-932-3030.
NOTE: The message “POWER FAILURE” is not a system error. When this message is displayed, it indicates that
power to unit was interrupted and then restored. To clear the message, press the MENU SELECTION key.
