Why flow indicator on Pentair AUTOTROL 368 controller does not display service flow?
- MMary 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.
