Err1, Err3 or Err4 Valve motor failure If the valve motor doesn’t run, unplug the water softener and check the valve motor wire harness for damage or a loose connection. Reconnect the valve motor wire harness if disconnected. 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 run and spins the rotor valve constantly, the position switch may be defective. Replace the position switch if it doesn’t detect the rotor valve position.
