    Why flow indicator on Pentair AUTOTROL 368 controller does not display service flow?
    • M
      Mary GarciaSep 15, 2025
      If the flow indicator on your Pentair Control Unit controller isn't displaying service flow, first ensure the bypass valve is not in the bypass position. If it isn't, check if the meter cable is fully inserted into the valve. If the problem persists, the meter might be clogged with debris, requiring you to remove and clean it.

    Why is there hard water leakage after regeneration in my Pentair AUTOTROL 368?
    • L
      Laurie GordonAug 25, 2025
      If your Pentair Control Unit is experiencing hard water leakage after regeneration, it could be due to several reasons. First, try repeating the regeneration, ensuring the correct brine dosage is set. If the issue continues, check for a leaking external bypass valve and replace it if necessary. Lastly, inspect the O-ring around the riser pipe for damage and replace if needed.

    What to do if Pentair AUTOTROL 368 Control Unit will not draw brine?
    • C
      Cody WeeksAug 26, 2025
      If your Pentair Control Unit isn't drawing brine, it might be due to a restricted drain line, so remove the restriction. Another possibility is a plugged injector; clean the injector and screen. Also, check if any debris is preventing the valve discs from closing and remove any foreign matter.

    Why Pentair AUTOTROL 368 Control Unit backwashes or purges at excessively low or high rate?
    • D
      Dennis GonzalezSep 16, 2025
      If you find your Pentair Control Unit is backwashing or purging at an excessively low or high rate, it could be due to an incorrect drain controller being used. Replace it with the correct size controller. If there is no drain line flow controller installed, install one. Also, check for any restrictions in the drain line and remove them.

    What does error E3 mean on Pentair AUTOTROL 368 Control Unit?
    • J
      jeffery77Dec 1, 2025
      If your Pentair Control Unit displays "E 3", wait until the controller returns to the service position. If the camshaft is not turning during the "E 3" display, check the motor connection and the motor wire harness connection to both the motor and the controller module. Also, verify the optical sensor connection and placement, and check if the motor gear has engaged the camshaft. If everything is connected, replace components in this order: 1. Motor Assembly and optical Sensor. 2. Controller. If the camshaft is turning more than 5 minutes to find Home position, verify if the optical sensor is in place and connected to the wire and inspect for debris in the camshaft slots. If the motor continues to rotate indefinitely, replace the following components in this order: 1. Optical Sensor. 2. Co...

    What to do if Pentair AUTOTROL 368 has flowing or dripping water at drain or salt line after recharge?
    • E
      Erik MorrisSep 8, 2025
      If there's flowing or dripping water at the drain or salt line after recharge, it could be that debris is preventing valve disc #3 or #4 from closing, so remove the debris. Alternatively, valve discs #3 or #4 might be worn and need replacement.
