Spa source checklist

Hot Spring and Caldera spa troubleshooting checklist

Hot Spring, Caldera, and other Watkins-style systems can involve proprietary controls, circulation, salt/mineral systems, and dealer-specific part paths. Capture proof before parts or board assumptions.

Capture first

1. model and serial2. control screen3. circulation status4. filter proof5. salt/mineral status6. cover condition7. water readings8. trip timing

Field-safe checks

  1. Separate circulation symptoms from heat, sanitation, and control display symptoms.
  2. Check filter condition and water level before pump or heater assumptions.
  3. Document salt/mineral cartridge status and water age before chasing sanitizer drift.
  4. Use dealer support for proprietary controls, boards, harnesses, and energized checks.
