Spa shuts off unexpectedly after running for a while (no error code)

Safety first: Allow the unit to cool before restarting to avoid damage.

• Check ventilation: Ensure there is adequate space around the pump/heater unit and that vents are not blocked by walls, covers, or debris.
• Limit continuous use: Avoid running the blower or pump at maximum for extended periods in hot weather.
• Cool-down period: Let the spa rest for 30–60 minutes before restarting.

If shutoffs become frequent even with good ventilation, internal components may be overheating due to wear and should be inspected by a technician.
