Davey – EcoSalt 20 Replacement Electronic PCB (Controller Board)

This is the genuine Davey replacement printed circuit board (PCB) for the EcoSalt 20 (BMSC 20) salt water chlorinator. The PCB is the heart of the controller unit, managing chlorine output levels, safety cut-offs, low-salt and no-flow indicators, and all user interface functions. It is typically replaced when the chlorinator displays erratic behaviour, fails to respond to controls, shows a blank or frozen display, or stops producing chlorine despite a healthy cell.

Compatibility

This PCB is designed specifically for the Davey EcoSalt 20 / Monarch Chloromatic BMSC 20 salt chlorinator — the 20 g/h output model. It is not interchangeable with other output variants (such as the BMSC 13 or BMSC 26), as each model operates at a different voltage and control configuration. Always verify your chlorinator’s model label before ordering.

Why Genuine Matters

As a genuine Davey spare part (European variant), this PCB is built to the exact electrical specifications of the original, ensuring reliable communication between the power supply, the electrolytic cell, and all onboard safety features including the low-salt shutdown and integrated flow-switch logic. Aftermarket boards risk incompatibility, voided warranties, and potential damage to the cell.

Installation

PCB replacement involves working with mains-voltage components inside the chlorinator enclosure and should be carried out by a qualified pool technician or electrician. Ensure the unit is fully isolated from power before beginning work, and follow Davey’s installation and operating instructions for the EcoSalt 20 throughout the procedure.
