There are two things you can check, there is a tranformer that plugs into the main circuit board(usually a four wire plug). Unplug and check pins for good connection and then reconnect There are usually one or two fuses inside the control box mounted on or near the circuit board. Turn off power to spa and pull fuses and check continunity. This is a good start.

It sounds as if the relay is not latching on the circuit board for that tub. You probably want to have a Jacuzzi service tech come and take a look at it.

They should have an online manual of the website. Look that up or call costumer service
