V. Diagnosing by CLICKS
I have found over the years that many failures can be determined by the
CLICKS the board makes. The CLICKS are relays closing on the board.
Since all of the boards used by Jacuzzi Whirlpool Bath spas were made by
Balboa Instruments, the CLICKS follow the same sequence.
What each CLICK means:
CLICK #1
When power is first applied to the spa, the board will produce an audible CLICK.
If it does you have power to the board.
The board does a self test. This test includes checking the sensors. It looks to
see the temperature and overheat sensor are within tolerance and close to
identical. It also checks the pressure switch to confirm it’s open. If everything is
fine.
CLICK #2
The #1 pump comes on. If the spa sees the water moving, then…
CLICK #3
The heater light comes on and the spa starts heating.
CLICK #4
The spa turns on the ozonator if so equipped.
OK, lets diagnose using the CLICKS:
NO CLICK #1
You power up the spa and you do NOT get a click.
Cause of Failure: First thing to check is incoming power. You MUST use a meter
to confirm proper voltage. Using a volt pen that lights up when power is present
won’t work. You must confirm you have 110-130vac if you have a single pump
system and 220-260vac if you have 2 or more pumps.
