Zodiac – GSOT TNG power supply board – R0842100

The Zodiac R0842100 is an original replacement power supply board designed specifically for Zodiac GSOT TNG series robotic pool cleaners. As the central electronic component responsible for converting and distributing electrical power throughout the robotic unit, this board plays a fundamental role in the correct and safe operation of the cleaner. Without a functioning power supply board, the robot cannot receive the regulated voltage needed to drive its motors, sensors, and control circuits. This is an OEM spare part, manufactured to the exact specification of the original component installed during production.

Technical characteristics and compatibility

The power supply board (tarjeta de alimentación in Spanish) is the electronic heart of the GSOT TNG robotic cleaner’s control system. It is responsible for regulating and distributing the electrical supply to all internal components of the robot, including the drive motor, brush motor, and any onboard control electronics. As an original Zodiac spare part carrying SKU R0842100, it is engineered to match the precise electrical tolerances, connector layouts, and form factor of the unit it was designed for. Using a genuine OEM board ensures full compatibility with the existing wiring harness, housing, and control logic of the GSOT TNG model, avoiding the risks associated with third-party substitutes that may not meet the original electrical specifications. Installation should be carried out by a qualified technician, as the repair involves internal electronic components of a low-voltage pool appliance.

Suitability and intended application

This power supply board is intended exclusively for Zodiac GSOT TNG robotic pool cleaners that exhibit symptoms of power failure, erratic behaviour, failure to start, or intermittent operation caused by a defective or damaged power board. It is suitable for residential pool environments where the GSOT TNG robot is deployed. If your robotic cleaner no longer powers on, loses power during a cleaning cycle, or displays irregular behaviour that has been traced to the power supply board, this genuine replacement component is the correct solution. Always verify your robot’s model designation and internal board reference before ordering to confirm fitment.
