Remove and Replace a System Circuit Board
Removing BP Expander Board, an Alternate Way
IMPORTANT!
BE SURE TO TURN THE POWER OFF BEFORE
REPLACING ANY COMPONENT, ESPECIALLY A
CIRCUIT BOARD.
IMPORTANT!
DO NOT REMOVE AND REPLACE THE CIRCUIT
BOARD UNLESS THE FAULT HAS POSITIVELY BEEN
DETERMINED TO BE THE CIRCUIT BOARD.
REMOVING A SYSTEM CIRCUIT BOARD
Shut OFF line power to the spa at the main circuit breaker
UÊ
panel. Do not attempt to service a spa without shutting off
the power. Serious injury or damage may result. Consider
placing a padlock on the main service disconnect box while
working on the spa.
Before you begin, consider labeling all wires that will
UÊ
be removed from the board. This may help speed up
reinstallation. Other technicians prefer to take the board
out with wires intact, place both defective and new board
side by side on a bench, then swap wires, recheck the logic
jumpers, and DIP switch for proper configuration. Whatever
technique is used, a wiring diagram should always be used
to ensure proper wire placement.
Remove the sensor wire connectors at the board, and the
UÊ
J44 heater connector on the BP2000 Board (located to the
left of the transformer). Be sure to use the release tab on
the connectors; do not pull on the wires.
Some BP spa control systems use an
UÊ
expander board.
Removing the expander board first simplifies the process.
To remove it, remove the screw, and then gently squeeze
the locking flange on each standoff with needle nose pliers
while lifting the board out. Some technicians, after removing
the screw (and if the standoffs allow it), gently pry the board
up where there’s a plastic stand off. Do not use excessive
force if the standoff will not yield. Do not pry up directly into
the board as damage to the board may result.
Remove the seven screws (if BP2000, see illustration).
UÊ
The board should now be free and can be removed from the
UÊ
system box.
