Hot tub not heating? Here's Who to Call
A hot tub that runs its jets but fails to heat the water makes it unusable, especially in cooler weather. The problem often stems from a faulty heating element, a tripped high-limit sensor, low water flow through the heater, or a malfunctioning control board. A pool and spa technician tests the heater, sensors, and flow switch, replaces the defective component, and calibrates the thermostat so the tub reaches and maintains the set temperature reliably.
