The circuit board is the part of the spa system that sends electronic messages to heat the water, turn on or turn off the pump, etc. It is a metal plate with wires, resistors, capacitors, and relays running across it in a complex grid. It may have transformers and spa fuses mounted directly on it, as well. Like any metal parts, water and the elements can be hard on the wiring and connections
