Why this course

A spa control board doesn't just supply power. It decides when to supply it. That one idea changes how you diagnose everything. A pump sitting idle might not be faulty or unpowered at all; the board may simply have decided conditions aren't right to run it. Advanced faults rarely sit in one place. They live where electrical, hydraulic, mechanical and water chemistry systems meet. This course teaches you to think like the board. You'll learn how sensor inputs become component outputs, how firmware logic shapes a spa's behaviour, why fault codes can mislead you, and how to work any fault through a five-stage pathway, whatever the brand. Written for Australian and New Zealand technicians, it also covers shell repair, ethical quoting and documentation, and draws a clear line around where your licence ends. The result is fewer guesses and fewer callbacks, plus the confidence to take on the faults that stump everyone else.
