Swim spa source checklist
Master Spas H2X swim spa troubleshooting checklist
For H2X and Master Spas swim spa calls, separate water movement, current system behavior, topside mode, filtration, heat, and GFCI timing before guessing at pumps, packs, or sensors.

Field-safe checks
- Confirm water level, filter condition, and valve positions before pump assumptions.
- Compare each pump or jet bank, not just overall current strength.
- Document whether heat loss is mode, cover, ambient, flow, or heater related.
- Hold electrical, pack, drive, and heater testing for qualified service.
Source route
Use the current Master Spas owner manual or dealer support route for model-specific controls, pump diagrams, and safety instructions.
