Why Is The Light On My Hot Tub Flashing?

Many times a flashing light on your hot tub is an easy fix, so before you start to worry follow the steps below to troubleshoot the issue.

Please follow the steps below to troubleshoot reasons your hot tub may be flashing.

  1. Ensure the hot tub is heating. If the hot tub is not heating, the light is blinking because the water temperature has dropped more than 2 degrees from the set temperature. If this is the case and the hot tub is not heating, please see our article on "What Do I Do If My Hot Tub Stopped Heating". If the hot tub is heating, proceed to the next step.
  2. The type of sanitation system your hot tub is equipped with will determine the next actions to take.
    1. If the hot tub is heating and you have an ACE-equipped model or a FreshWater-equipped salt water model, the salt system is most likely requiring attention. Go into your control panel and select the Salt Water option. Read the message and follow the on-screen instructions.
    2. If the hot tub is not equipped with either salt water system, power the tub off at the breaker or unplug. Remove the filter(s). Leave the tub powered off for 1-2 min. Then, power the tub back on and leave the filters out of the spa. If the light is still flashing, please call to schedule a visit with a technician. If the light stops flashing you will want to clean your filter in a soaking solution or replace depending on the age of the filters.
