Water Softener - Error Code

Many water softeners have a self-diagnostic function for the electrical system.  The softener monitors electronic components and circuits for correct operation. If a malfunction occurs, an error code will appear in the display which indicates an electrical problem in the timer, the motor, the wiring, etc.

If there is an error code detected, the blue indicator light will flash 4 times every second and the display will flash ERR.  An alarm will beep every 30 seconds (from 8:00am to 8:30pm) to signal that the softener requires service. The alarm can be turned off by pressing any button but the blue indicator light and display will flash.

If an electrical spike takes place from an incoming power line in your home, disconnect the power, unplug the power transformer from the wall outlet and wait for several minutes, then plug the transformer back in.  The normal light should display and the motor may run for several minutes while the unit resets.

If you just installed your water softener, it is possible that you have a loose or disconnected wiring in the control. Contact your installer or check for the following:

  1. Unplug the power cord (transformer) from the wall outlet.
  2. Remove the front control cover. Push in on the snaps on each side to remove the cover.
  3. Pull the cover forward slightly and rest the front on the top of the tank.
  4. Make sure that all the wires are pressed firmly in place.
  5. Check the blue color double wires on the left, the black double wires on the right, and the two connector blocks. Make sure that these wires are connected.
  6. After having checked the connections, re-assemble the control front by aligning the cover with the snaps on the side. Press down slightly and the cover will snap in place.
  7. If a loose connection was found, and the power is restored, the control will need to be set.
