  Error code 1006 on your Sterling Water Dispenser indicates the MAV/SEPS/ NHBP/AUX MAV motor ran too long while looking for the park position. To resolve this: * Enter the cycle programming level and verify the second parameter is set to ALT oFF. * Remove the piston and seal assemblies for inspection and repair or replacement, then reset the control valve by holding the 'NEXT' and 'REGEN' buttons for 3 seconds.

Why is my Sterling Water Dispenser producing hard water or not using salt?

  There are several reasons why your Sterling Water Dispenser might be producing hard water or not using salt. Here are a few things you can check: * Make sure the softener has uninterrupted power. * Ensure there is enough salt in the brine tank. If the salt has formed a bridge, try hitting the side of the tank with a rubber mallet to break it up. * Verify the bypass valve is in the 'Service' position. * Check the drain line for any issues. * Review the control valve programming. Also, verify the drive motor is connected to the control valve circuit board connector J1 (labeled “MOTOR”) and that the meter cable (grey cable, 3 pins) is connected to control valve circuit board connector J2 (labeled “METER”). * Confirm that the softener is properly sized for your actual service flow...
