What to do if the Pentair AUTOTROL 460TC Control Systems timer is stalled in regeneration?
- J
  Joseph OwenAug 17, 2025
  If your Pentair Control Systems timer is stalled in the regeneration cycle, there are several potential causes. It could be due to a dead motor, a motor running backwards, lack of electric power at the outlet, a broken gear, a defective switch, an air leak in brine connections, binding of the camshaft, water pressure exceeding 125 psi during regeneration, or a defective circuit board. Addressing these issues involves actions like replacing the timer, checking junction points for air leaks, removing obstructions from valve discs or the camshaft, installing a pressure regulator or repairing the outlet.

Why does my Pentair Control Systems clock not show the correct time?
- P
  Paul HarrisonAug 19, 2025
  If your Pentair Control Systems clock isn't displaying the correct time, it might be because the outlet is operated by a switch, the voltage or frequency is incorrect, or there have been power outages. Try using an outlet not controlled by a switch, replacing the timer with one of the correct voltage and frequency, or resetting the clock.

Why do I run out of soft water with Pentair AUTOTROL 460TC Control Systems?
- C
  Corey DonaldsonAug 26, 2025
  If your Pentair Control Systems are running out of soft water between regenerations, it could be due to several reasons: improper regeneration, fouled softener resin, incorrect salt setting, incorrect hardness or capacity settings, increased water hardness, restricted meter turbine rotation, or excessive water usage below 1/5 gallon per minute. You can try repeating the regeneration with the correct salt dosage, using a resin cleaner, setting the salt control to the proper level, correcting the hardness or capacity settings, adjusting the hardness setting, freeing up the turbine and flushing with clean water, or repairing leaky plumbing and fixtures.

  If your Pentair Control Systems control will not regenerate automatically or when the button is pressed, possible causes include the electric cord being unplugged, no electric power at the outlet, a defective motor, a broken gear, binding in the gear train, or a defective switch. Suggested solutions include connecting the power cord, repairing the outlet, or replacing the timer.

  Joseph RichAug 30, 2025
  If your Pentair Control Systems clock does not display the time of day, the issue might stem from an unplugged transformer cord, lack of electric power at the outlet, a defective transformer, or a defective circuit board. Try connecting the power, repairing the outlet, replacing the transformer, or replacing the timer.

Why Pentair AUTOTROL 460TC regenerates only when button is pressed?
- J
  Jorge MorenoSep 1, 2025
  If your Pentair Control Systems control will not regenerate automatically but will regenerate when the button is pressed, it could be due to an inoperative water flow display, a defective circuit board, or incorrect hardness and capacity settings. You can refer to the troubleshooting steps for 'No water flow display when water is flowing', replace the timer, or set the hardness and capacity settings to the correct values.

What to do if Pentair Control Systems time display is incorrect?
- C
  Corey AverySep 4, 2025
  If the Pentair Control Systems time display shows something other than the time of day, it could be due to electrical interference or a defective circuit board. Try disconnecting power to the unit, restoring power, and resetting the time of day display, or replacing the timer.

Why does Pentair AUTOTROL 460TC Control Systems have continuous regeneration?
- M
  Michelle SimmonsSep 7, 2025
  If your Pentair Control Systems has continuous regeneration where the camshaft doesn't stop at the end of regeneration, it could be due to a broken switch activator on the gear or a defective switch. In either case, you should replace the timer.

What causes no water flow display on Pentair AUTOTROL 460TC Control Systems?
- M
  Mary McdanielSep 10, 2025
  If there's no water flow display when water is flowing in your Pentair Control Systems, it could be due to the bypass valve being in bypass, the meter probe being disconnected or not fully connected, restricted meter turbine rotation, a defective meter probe, or a defective circuit board. Try shifting the bypass valve, fully inserting the probe, removing the meter housing to free up the turbine and flush with clean water, or replacing the timer.
