Fluidra - pH/ORP Driver Board Assembly for Ei2 iQ Series

Fluidra – pH/ORP Driver Board Assembly for Ei2 iQ Series

This is the genuine Fluidra pH/ORP driver board assembly (PCB) designed for the LC2 series controllers within the Fluidra Ei2 iQ salt chlorination range. It is the internal electronic board responsible for receiving, processing and acting on signals from the pH and ORP (redox) sensors, enabling the control unit to regulate water chemistry automatically. Replacing a faulty driver board restores accurate pH monitoring and ORP-based chlorine regulation to your salt chlorinator system.

Compatibility

This driver board assembly is a factory spare part for the Fluidra Ei2 iQ pH series salt chlorinators using the LC2 controller platform, including the Ei2 iQ pH 12, Ei2 iQ pH 20 and Ei2 iQ pH 25 models. It is not a universal component — always verify your unit’s controller series against the SKU before ordering.

Why Genuine Matters

Fluidra’s official guidance is to use only genuine replacement parts in their electrolysis systems. An original Fluidra driver board ensures precise sensor signal handling, full compatibility with the unit’s firmware, and preserves any remaining manufacturer warranty. Third-party equivalents may cause calibration errors, false alarms or sensor reading failures that are difficult to diagnose.

Installation

Replacement of internal electronic assemblies must be carried out by a qualified pool technician or authorised Fluidra service engineer. Always disconnect the control unit from the mains power supply and ensure no water is flowing through the system before beginning any work. Refer to the official Fluidra Ei2 iQ service manual for step-by-step disassembly and reassembly procedures.
