Balboa Spa Pack - GS500Z

2 & 3kW - Replacement Parts Only

Ongoing Support & Replacement Parts Available

The Balboa GS500Z spa pack has been a reliable choice for hot tub owners, but as it is being phased out and no longer fitted to new models, finding full replacements can be challenging. While we no longer supply the complete pack, we continue to stock all essential components to ensure uninterrupted support for existing units.

Our inventory includes everything except the plastic box, with the replacement PCB as the main component, configurable for both 2kW and 3kW use. Whether you need a new circuit board or other critical parts, were here to help keep your spa running smoothly.

Explore our full list of parts below, watch our helpful video, or download our catalogue for a complete overview of all available components.

Need assistance choosing the right parts? Get in touch, and well ensure you find exactly what you need.
