This DIY repair guide explains how to replace the valve motor in a water softener. The valve motor moves the valve rotor that controls water flow during the softening and regeneration cycles. If the valve motor stops working, the rotor won't move. You'll notice that the water isn't soft and the softener isn't using up salt. Replace a broken valve motor with the manufacturer-approved replacement part.
Use this repair guide and video to replace the valve motor in Kenmore, Whirlpool and GE water softeners.
