Replace the valve motor wire harness if damaged. If the motor runs but the rotor valve doesn't move, the problem could be a defective motor or a locked-up rotor valve. Replace the valve motor if defective. Replace the rotor valve if it's locked up. If the motor runs and spins the rotor valve constantly, the position switch may be defective.

Kenmore water softener codes
A Kenmore water softener shows codes for salt level, regeneration and the control valve. Check the brine tank for salt and break up any salt bridge, make sure the unit is plugged in and the bypass valve is open, and run a manual regeneration. Hard water after a power cut often means the softener lost its settings.
Reset the clock and hardness setting after a power loss. A code that continues after salt and power are right points to the control valve or a sensor and needs a service visit.
Water softeners work by exchanging hardness minerals for sodium or potassium from the salt, and they need to regenerate on a schedule. If your water has begun to feel hard, soap does not lather and scale returns, the softener may not be regenerating, so check the salt level, the brine tank for a bridge and the control's clock. Test the water with a hardness strip before and after the softener to see whether it works. A service call can clean the injector, which blocks with sediment.
What is a salt bridge?
A hard crust in the brine tank that stops salt dissolving. Break it with a broom handle and add salt.
How do I test whether the softener works?
Use a water hardness test strip before and after it.
