Hot Tub Pressure Switch

The hot tub pressure switch is an integral part of any hot tubs equipment. Installed on the heater unit, the pressure switch will measure the water pressure travelling through the heater to make sure that it is not heating whilst suffering low pressure or no flow due to a pump failure or blockage.

The pressure switch will relay the information to the spa pack control board that then sends the information to the top side panel with an error code.

The following codes will warn you of either a pressure switch or flow switch failure:

  • FLO
  • FL
  • FLC
  • FL1
  • PS
  • Blinking Lights
