I am trying to replace the transformer cable on ESM9CE+ Currant transformer is faulty. Both cables are black with no indication of polarities. How do I identify the polarity on the back of the PCB board?

To identify the polarity on the back of the PCB board for the EcoWater ESM9CE+ transformer cable replacement, refer to the schematic:
- Red wire is labeled as +5 (positive) - Black wire is labeled as GND (ground/negative)
Ensure the transformer outputs 24VAC, and connect the wires according to the color codes and labels on the control board.
Need help?
