What you'll learn

  • Diagnose, don't guess

    Learn a proper step-by-step method for tracing a fault back to its real cause instead of swapping parts and hoping.

  • Spot a real leak vs. just evaporation

    Use a simple bucket test to check, then learn how to track down where a genuine leak is actually coming from.

  • Work safely and cover yourself

    Learn how to properly isolate a spa, know when to call in an electrician, and document what you did.

Why this course

Every spa technician has done it: replaced a perfectly good heater, sensor, or pump because it seemed like the obvious culprit — only to have the same fault turn up again next week. It's frustrating for you, expensive for the client, and it chips away at the trust you've worked hard to build. Spa Diagnostics Fundamentals teaches you to read a fault properly before you touch a single component. You'll learn how a spa's electrical and hydraulic systems actually work together, so when a symptom shows up — no heat, a tripped RCD, an error code, a slowly dropping water level — you know how to trace it back to what's really going on, rather than starting with the most expensive part and working backwards. Built specifically for the Australian and New Zealand market, the course walks through real fault symptoms, real case studies, and the safety and reporting standards you're expected to work to. By the end, you won't just know what to check — you'll know why, which means fewer callbacks, faster jobs, and clients who trust your diagnosis the first time.
