Fluidra - Control PCB Board Assembly for Ei2 iQ 25 Salt Chlorinator

Fluidra – Control PCB Board Assembly for Ei2 iQ 25 Salt Chlorinator

This is the genuine Fluidra replacement control PCB board assembly for the Zodiac Ei2 iQ 25 salt chlorinator. The circuit board is the electronic heart of the unit, managing chlorine production output, electrode polarity reversal (auto-cleaning), safety cut-outs, and connectivity functions. Replacing a faulty board restores full, correct operation of the chlorinator without replacing the entire unit.

Compatibility

This PCB assembly is designed exclusively for the Fluidra Zodiac Ei2 iQ 25 salt chlorinator. The Ei2 iQ range are wall-mounted saline electrolysis systems for residential swimming pools, featuring automatic electrode cleaning and Fluidra Pool app connectivity. Always verify your model designation before ordering, as PCB assemblies are model-specific and are not interchangeable across the Ei2 product family (e.g. Ei2 12 or Ei2 20).

Why Genuine Matters

A genuine Fluidra board is manufactured to the exact electrical tolerances of the Ei2 iQ 25, ensuring correct regulation of power to the electrolysis cell, accurate safety-device responses, and reliable wireless connectivity. Non-genuine boards risk incompatible firmware, improper cell protection, and voided equipment warranties. Fitting a genuine part also preserves the IPX5-rated integrity of the control enclosure.

Installation

Board replacement requires disconnecting mains power before any work begins, in compliance with IEC 60947-1 and IEC 60947-3 standards for omnipolar isolation. Due to the mains voltages involved and the need to correctly reseat all connectors and wiring harnesses, this work should be carried out by a suitably qualified technician. Retain the original user manual for connector reference diagrams.
