Spa source checklist
Marquis, Coast, Arctic, and Wellis spa troubleshooting checklist
When a spa brand is less familiar to the tech, the proof packet matters more: brand/model, controller family, visible components, symptoms, and boundaries before guessing a pack, topside, pump, or heater.
Capture first
1. brand/model label2. controller family3. topside message4. pump labels5. filter proof6. heat/GFCI timing7. ozone status8. cover condition
Field-safe checks
- Identify the installed control system before ordering brand-facing parts.
- Use visible proof, not cabinet assumptions, for pumps, packs, topsides, and accessories.
- Keep customer notes focused on symptoms and next verification, not final diagnosis.
- Route energized tests and proprietary control issues to qualified service.
