Zodiac – Inboard card CX – R0818500

The Zodiac Inboard Card CX (SKU R0818500) is a genuine Zodiac replacement electronic circuit card designed for compatible Zodiac CX-series automatic pool cleaner systems. As an original manufacturer spare component, this inboard card serves as the core control board responsible for managing the operational logic and electrical functions of the cleaner unit it is installed in. Replacing a faulty or damaged inboard card with an authentic Zodiac part ensures that the cleaner continues to perform as originally engineered, maintaining reliable and consistent pool cleaning cycles.

This type of control card governs the electronic behaviour of the pool cleaner, including directional movement sequences, motor drive signals, and other automated functions that enable the unit to navigate and clean pool surfaces effectively. Using a genuine Zodiac replacement part rather than an aftermarket alternative preserves the integrity of the system and ensures full compatibility with the original hardware and firmware specifications of the CX-series cleaner.

Compatibility and installation context

The R0818500 inboard card is specifically engineered to fit within the Zodiac CX-series automatic pool cleaner platform. If your Zodiac CX cleaner is exhibiting erratic behaviour, failing to start, or showing signs of electronic malfunction, the inboard card is one of the primary components to inspect and replace. Installation should be carried out by a qualified technician or an experienced pool service professional to ensure correct handling of electronic components and to avoid damage to the unit.

As with all electronic spare parts, it is important to verify the exact model and series of your pool cleaner before ordering, as circuit boards are not universally interchangeable between different cleaner families or generations. The SKU R0818500 is the Zodiac part reference that should be used when sourcing this component through authorised Zodiac distributors or specialist pool equipment retailers.

Suitability and practical buying guidance

This replacement inboard card is intended for pool owners and pool service professionals who need to restore full functionality to a Zodiac CX-series automatic pool cleaner without replacing the entire unit. Choosing a genuine Zodiac OEM part is strongly recommended over generic alternatives, as the electronic specifications must match precisely for the cleaner to operate safely and reliably. This component is not a standalone product and has no function outside of the cleaner system for which it is designed. If you are unsure whether this is the correct part for your specific cleaner model, consult the Zodiac documentation or contact an authorised Zodiac service centre before purchasing.
