Additional Information

This is a genuine licensed Spaform PCB manufactured by Balboa.

Special Note

If your Spaform spa has only 2 pumps and a blower you can save yourself some money and buy the 2 pump generic version which can be found here. If your spa has 3 pumps and a blower then you will require this PCB as the 2 pump model will not work.

This PCB should be fitted with all the dip switch settings set to the same position as your faulty PCB and should be fitted by a qualified tradesman or competent person as an incorrect installation will void Balboa's manufacturers warranty. All Balboa PCB's are fully tested before they are dispatched to customers and are non returnable once they have been powered up.
