AutoPilot Pool Pilot “Purifier Off, Check Flow” Error Message Troubleshooting

  • Proper water flow is essential to the operation of your AutoPilot Pool Pilot salt chlorine generator.
  • If your Pool Pilot controller displays the “Purifier Off, Check Flow” message any and all chlorine production has ceased until the message is corrected.
  • When the “Purifier Off, Check Flow” message is displayed you should ignore any other readings on system including salt, temperature and volt/amp readings until the issue is resolved. 

General Pool Flow Issue

  • Is the pool pump turned on? Does water appear to be returning to the pool in a normal fashion or is flow weakened?
  • Check / clean pump and skimmer baskets.
  • Pool filter could be clogged/dirty.
  • Improperly positioned valves. Ensure that no valves are diverting or blocking flow away from the Pool Pilot manifold assembly.

Variable or 2 Speed Pool Pump

  • If your pool has a variable or 2 speed pool pump installed you will want to ensure that the pump is pushing enough water to activate the flow switch. Although the Pool Pilot only requires about 15-20 gallons per minute of water flow low speeds or low speeds combined with other conditions (i.e. dirty filter, certain plumbing configurations, etc.) could cause issues activating the flow switch.
