When changing the control board, check the software version on the chip. Example- V1.40. If the chip on the
replacement board has an older software version than the board being replaced, carefully remove the chip from the
old board and place it in the new board. Use a chip puller if one is available.
Brewer: The spray plates should be removed and cleaned periodically to remove hard water deposits. In areas
with extremely hard water, it may be necessary to do this weekly. Monthly cleaning may be sufficient in areas with
average water conditions.
