Hot Tub Part guide on:
Spaform PCB upgrade
If you are unlucky enough to have a Spaform hot tub with the older Elite Balboa PCB and you need to replace this then this guide is for you.
The current list of discontinued Spaform / Balboa boards includes: SF100 SF172 and Sf273 circuit boards.
The following control system upgrades are designed to give you the easiest method to replace your current M3 Balboa control system and bring it up to the new M7 Balboa control system that you can get spares for.
Note the only other thing you would need to change would be the cable ends, because the hot tub parts now connect directly onto the board using a 4 pin AMP connector instead of the old grey JJ plugs that go into the side.
This consist in most cases of simply having to change the control box that has a new circuit board heater and sensors built in.
