What to do if Autotrol Control Unit will not regenerate automatically?
- C
  Charles HartAug 21, 2025
  If your Autotrol Control Unit isn't regenerating automatically but does when you press the button, and the water flow display isn't working, refer to Item 5 for troubleshooting steps. Alternatively, the issue might stem from a defective circuit board, in which case you should replace the timer. It could also be due to incorrect hardness and capacity settings, which you can correct by referring to the Programming section.

Why is my Autotrol 255-460i timer stalled in regeneration cycle?
- A
  Adam WelchAug 23, 2025
  If the Autotrol Control Unit timer is stalled in the regeneration cycle, several issues could be at fault. The motor may be dead or running backward, necessitating a timer replacement. A lack of electrical power at the outlet requires repairing the outlet or using a working one. A broken gear or defective switch also calls for a timer replacement. Additionally, air leaks in brine connections should be checked and corrected at all junction points. Binding of the camshaft may occur due to foreign object obstruction from valve discs or the camshaft, which needs to be removed. High water pressure during regeneration (greater than 25 psi) requires installing a pressure regulator. Finally, a defective circuit board also requires a timer replacement.

What causes Autotrol 255-460i Control Unit to not draw brine?
- M
  Mark WelchAug 25, 2025
  If your Autotrol Control Unit is not drawing brine, it could be due to several reasons. Low water pressure can be resolved by making the correct setting according to the instructions. A restricted drain line needs the restriction removed. A plugged injector requires cleaning the injector and screen. If the injector is defective, replace the injector and cap. If valve disc 2 and/or 3 are not closed, remove any foreign matter from the disc and check the disc for closing by pushing in on the stem, replacing if needed. Lastly, if the air check valve is prematurely closed, put the control momentarily into brine refill and replace or repair the air check if needed.

  Darrell EstradaAug 27, 2025
  If your Autotrol Control Unit regenerates at the wrong time of day, it could be due to power outages or an incorrectly set clock. In either case, reset the clock to the correct time of day.

What to do if Autotrol Control Unit will not regenerate at all?

  If your Autotrol Control Unit won't regenerate automatically or when you press the button, start by checking if the electric cord or transformer is unplugged and connect the power if needed. Also, ensure there's electric power at the outlet; if not, repair the outlet or use a working one. If those aren't the issue, the problem could stem from a defective motor, broken gear, binding in the gear train or a defective switch, all of which would require replacing the timer.

How to fix Autotrol 255-460i Control Unit when clock does not display time of day?
- B

  If the time display on your Autotrol Control Unit doesn't show the time of day, first check if the transformer cord is unplugged and connect the power if necessary. If that's not the issue, ensure there's electric power at the outlet; if not, repair the outlet or use a working one. If the problem persists, the transformer might be defective, requiring a replacement. As a last resort, a defective circuit board may be the cause, which means replacing the timer.

Why Autotrol 255-460i Control Unit using more or less salt than setting?
- T
  Timothy SalazarSep 3, 2025
  If your Autotrol Control Unit is using more or less salt than the salt control is set for, ensure you have made the correct setting. If the setting is correct, foreign matter in the controller could be causing incorrect flow rates; in this case, remove the variable salt controller and flush out any foreign matter, manually positioning the control to brine draw to clean the controller (afterward, position the control to 'purge' to remove brine from the tank). If neither of these resolves the issue, the controller itself may be defective, and you should replace the defective part.

Why Autotrol 255-460i Control Unit camshaft does not stop at end of regeneration?
- P
  Patricia ChaseSep 4, 2025
  If the Autotrol Control Unit is continuously regenerating and the camshaft doesn't stop at the end of regeneration, it could be due to a broken switch actuator on the gear or a defective switch. In either case, you should replace the timer.

Why does Autotrol 255-460i time display continue to advance?
- T
  Teresa GarrisonSep 6, 2025
  If your Autotrol Control Unit's time display continues to advance, it is caused by a defective time set switch, which means you need to replace the timer.

  If your Autotrol Control Unit clock doesn't display the correct time of day, check if the outlet is operated by a switch and use an outlet not controlled by a switch. Also, verify that you're using the correct voltage and frequency (Hz); if not, replace the timer with one of the correct voltage and frequency. Finally, power outages can cause this issue, so try resetting the clock.
