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

  1. Identify the installed control system before ordering brand-facing parts.
  2. Use visible proof, not cabinet assumptions, for pumps, packs, topsides, and accessories.
  3. Keep customer notes focused on symptoms and next verification, not final diagnosis.
  4. Route energized tests and proprietary control issues to qualified service.
