Below are troubleshooting charts with causes and solutions for common water softener problems. Need help troubleshooting? Call 1-888-64WATER (1-888-649-2837).

Tools needed for most repairs:

  • 5/16 Hex Driver
  • Phillips Screwdriver
  • Needle-nose Pliers

Brine tank full of water, No soft water or Not using salt.

Solution: Disassemble and clean the nozzle and venturi:

Clean all parts using a soft tooth brush, mild soap and warm water. Use resin bed cleaner if parts are iron coated. Rinse with clean fresh water. Do not use any sharp or hard objects to clean bottom of item #6. Remove parts 1-7, 9 and 10. Set parts aside and clean. Reinstall cap (#1) and o-ring (#2).

Lift the brine valve assembly (#13) from the brinewell. Remove the plastic clip (#12) and pull the asembly apart.

Use the SELECT or TOUCH HOLD button to enter the unit into a manual regeneration and advance the valve to the fill position.

As the valve advances into FILL, there will be a flow of water from the tubing. Use this to wash down the brine valve assembly of any excess salt. Also wash down the brine well of excess salt. Move the bypass valve into BYPASS to shut off the flow of water to the valve. Use the toothbrush to thoroughly clean the nozzle and venturi (#6), flow plugs (#5 and #9) and screens (#4, #10 and #11). Carefully clean the flow plug center hole with a small wire.

Reassemble all parts in the nozzle venturi. BE SURE #& is installed correctly, numbers up on the flow plugs (#5 and #9). Advance the valve into the BRINE position. Place the bypass valve into service and check for suction on the tubing that connects to the brine valve assembly. If not, recheck the assembly of the nozzle venturi. If suction is now working, reinstall the brine valve assembly and finish the regeneration.

VALVE NOT WORKING

  • Water running to drain
  • Brine tank overflowing
  • Motor stalled
  • Water leaking from valve
Solution: Before you start to service a valve, make sure it is in the service position. Place bypass valve in bypass to shut off water. Loosen 3 of 5 hex screws at top back of valve. This will relieve pressure in the softener.
If water is running to drain in service, if brine tank is overflowing, or the motor is not turning the valve (valve stuck):
  1. Remove the 5 hex screws from the top of the valve and carefully remove the cover. Replace the seal kit parts #9 through #12. Be sure wear strip (#9) is placed on top of rubber seal (#10). Inspect the rotor for wear, scratches or cracks, and replace if needed. Check all o-rings for wear, cuts, flat spots, proper positioning, etc., and replace as needed. Install the valve cover and 5 screws. Turn the water on and check to see if failure is corrected.

If water is leaking from the top of the valve, or between #3 and #14, replace o-rings 4, 5 and 8. Turn water on and check again for leaks.

If the brine tank is overfilling, with little or no water flow from the valve drain hose during regeneration, check flow plug #1, drain elbow #2, and the valve drain hose for obstruction.
