Davey - EcoSalt 2 Control PCB Assembly DES2-25EL (25 g/hr Low-Salt) - 33005C-25ELSP

Davey – EcoSalt 2 Control PCB Assembly DES2-25EL (25 g/hr Low-Salt)

This is the genuine Davey replacement printed circuit board (PCB) assembly for the EcoSalt 2 DES2-25EL and DES2-25USL salt pool chlorination systems — the 25 g/hr low-salt variants. The PCB is the electronic brain of the power supply unit, governing chlorine output levels, cell polarity reversal, and the alarm and warning system. It is typically replaced when the control unit fails to respond correctly, displays persistent faults, or suffers damage from chemical vapour exposure.

Compatibility

This PCB assembly (part 33005C-25ELSP) is specifically designed for the Davey EcoSalt 2 DES2-25EL and DES2-25USL models — the 25 g/hr low-salt versions of the EcoSalt 2 range. It is not interchangeable with the standard-salt DES2-25E board (33005C-25ESP) or boards from the 15 g/hr or 35 g/hr variants. Always verify your exact model designation before ordering.

Why Genuine Matters

Davey explicitly warns that non-genuine or incompatible electronics can cause serious damage to the EcoSalt 2 system and will void the product warranty. Only genuine Davey PCB assemblies are designed and warranted to operate correctly with the EcoSalt 2 power supply, ensuring accurate chlorine output control, reliable low-salt cut-out protection at approximately 1,200 ppm, and correct cell polarity switching.

Installation

PCB replacement requires disassembly of the EcoSalt 2 power supply housing and involves mains-voltage wiring. All electrical connections must be carried out by a qualified, authorised electrician. The unit must be kept well away from acid fumes and chemical storage areas before, during, and after installation, as chemical vapours can corrode the new board.
