Why does my spa heater trip the high limit switch?
The high limit switch can also be tripped by low pressure or water flow. When the water slows down in the heater, this raises the temperature of the water as it exits the heater. Most high limits are set to trip when they sense water temperatures of around 140° .
When to turn off the heater in a spa?
The Hi-Limit shuts off the heater or spa equipment when it detects a water temperature of 109° – 116°. The Hi-Limit on most newer spas can be reset by turning off the spa’s main power supply, and allowing the water to cool to below 100°.

Why do you need a pressure switch on a spa heater?
Spa heaters need to have enough water flow, or more specifically, enough water pressure to operate. That is why your spa has a pressure switch, a simple device that senses the water pressure, or flow rate.
Why does my spa water heater not work?
The spa isn’t heating, or the water is a lot cooler than it used to be, but everything else seems operational. Your spa’s water passes through the filter before it moves on to the heater. If water flow is restricted by a dirty filter or debris in the Filter Housing, the heater may not operate.
