How to replace a water softener valve motor

How to replace a water softener valve motor

This DIY repair guide explains how to replace a water softener valve motor. The valve motor moves the valve rotor that controls water flow during the softening and regeneration cycles. If the water softener 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 water softener part.

Use this repair guide and video to replace the valve motor in Kenmore, Whirlpool and GE water softeners.
