Why does my Autotrol Control Unit show 'Check Salt Light'?
The 'Check Salt Light' on your Autotrol Control Unit indicates that there was no regenerant draw or insufficient regenerant detected during regeneration. Make sure there is enough salt/regenerant available. Check for regenerant draw and inspect the regenerant line for any leaks.
What to do if my Autotrol Control Unit regenerates at the wrong time?
If your Autotrol Control Unit regenerates at the wrong time of day, it means that the controller is set incorrectly. You should correct the time setting according to the instructions.
Why is my Autotrol Control Unit overflowing the regenerant tank?
A regenerant tank overflow in your Autotrol Control Unit can be caused by: * Uncontrolled refill flow rate: Remove the refill flow control to clean the ball and seat. * Air leak in the regenerant line to the air check: Check all connections in the regenerant line for leaks. * Drain control clogged with resin or other debris: Clean the drain control. * Aircheck ball on 255 valve prematurely seating due to air leak: Check all connections in the regenerant line for leaks.
Why is my Autotrol Control Unit leaking hard water after regeneration?
Hard water leakage after regeneration in your Autotrol Control Unit may occur due to: * Improper regeneration: Repeat regeneration after ensuring the correct regenerant dosage was set. * O-Ring around riser pipe damaged: Replace O-ring. * System capacity too low due to incorrect resin volume setting: Reset the control and program the resin volume to the correct setting.
What to do if there is no conditioned water after regeneration in my Autotrol Control Unit?
If there is no conditioned water after regeneration in your Autotrol Control Unit, it could be due to: * No regenerant in the regenerant tank: Add regenerant to the regenerant tank. * Injector plugged: Clean the injector and screen. * Air check valve closes prematurely: Quick cycle control into regenerant draw/slow rinse.
Why is my Autotrol Control Unit control not drawing regenerant?
If your Autotrol Control Unit won't draw regenerant, check for these potential issues: * Low water pressure: Make correct setting according to instructions. * Restricted drain line: Remove the restriction. * Injector plugged: Clean the injector and screen. * Valve disc 2 and/or 3 not closed: Remove foreign matter from the disc and check the disc for closing by pushing in on the stem. * Air check valve prematurely closed: Put the control momentarily into brine refill.
Why is my Autotrol Control Unit control not regenerating automatically?
If your Autotrol Control Unit will not regenerate automatically, it could be due to: * AC adapter or motor not connected: Connect the power. * Fouled or defective turbine: Clean or replace the turbine assembly. * Defective turbine cable: Replace the turbine cable.
Why is my Autotrol Control Unit backwashing at an excessively low or high rate?
If your Autotrol Control Unit backwashes or purges at an excessively low or high rate: * Foreign matter affecting valve operation: Remove the drain controller and clean the ball and seat.
What causes flowing or dripping water at the drain line in my Autotrol Control Unit after regeneration?
Flowing or dripping water at the drain or regenerant line after regeneration in your Autotrol Control Unit can be due to: * Debris preventing valve disc from closing: Remove the debris.
Why is my Autotrol Control Unit having intermittent regenerant draw?
Intermittent or irregular regenerant draw in your Autotrol Control Unit can be caused by: * Low water pressure: Set the pump to maintain 20 psi at the conditioner.
