Have a 3 zone spa with 3 pumps connected to a Balboa M7 (53672-02 2M7P3) controller pack and digital pad. When I push the Jets 3 button (Zone 3) there is an audible click but nothing happens. Zones 1 & 2 work fine, the spa heats and circulates without issue.
To test the #3 pump/motor I swapped the Zone 2 & 3 plugs where they connect to the control pack. The #3 pump and motor work fine. When reversed Zone 2 clicks and nothing happens. Put back to normal the result is consistent. The pumps & motors seem to be fine, there are no obvious loose connections, and the 4 fuses inside the controller pack test good with a meter. For some reason power is not getting to the Jets 3 pump.
Does the click indicate anything specific? Relay? Control pad, controller pack, circuit board, or something else? What more can I do to chase down the root cause? Thank you!

Thank you for your response. Is there any other test I can do to confirm it before spending the $$$ on a new board?

If you are comfortable using a volt meter then you can turn on the pump and once you have heard the relays click you can take a voltage reading coming off the board going to the pump. If you are not getting any power and the indicator is on the top side then your circuit board is bad.
