The pressure switch is a safety device designed to prevent overheating of the hot tub heater should a low or no-flow condition exist in the spa.

The pressure switch is located in the heater circuit. When the switch is closed (proper flow), voltage is transferred to the heater circuit when the control thermostat calls for heat. Activating the relay allows the heater to activate. When the switch is open (low flow), voltage to the heater circuit is interrupted regardless of the state of the control thermostat. This prevents the heater from activating until the low flow condition has been resolved.

WARNING: The pressure switch is a safety device and should never be bypassed or tampered with. Never attempt to calibrate the pressure switch.

The following are some of the most common causes of pressure switch tripping:

Dirty filters
Clogged heater return
Low water level
