Spa shell surface around jets or controls is warm or hot to the touch even when heater is off.

Safety first: Turn off power if you suspect overheating of electrical components.

• Observe run times: Check if pumps or heater are running continuously due to mode or sensor issues.
• Inspect insulation: Open the cabinet and ensure insulation is not packed tightly against the heater or motor, which can trap heat.
• Check ventilation: Make sure cabinet vents are not blocked and that there is adequate airflow around the equipment.
• Adjust settings: Reduce filtration cycle duration if pumps are running excessively.
