Mark T Personal Solutions Manager, February 26, 2010

A motor fault or a bad wiring harness causes the e1 error code. A simple test is to unplug the softener for 30 seconds. Plug it back in and listen. If you here a clicking or snapping noise, the motor has failed. This is the most common. If this is the case, I recommend that the seal kit and the rotor also be replaced wit the motor. When the seals or the rotor is worn out, it will cause binding and cause the motor to fail. To replace the parts put the softener in bypass so there is no water going to the unit. Remove the electronics and set them aside so they do not get wet. Next remove the two screws in the motor and the 5/16 headed screws that hold the body together. Now remove all of the seals in the body. The top portion of the body has two seals that go around the rotor shaft. Sometimes the top seal sticks inside of the body and does not come out with the rotor. Use the grease that comes with the seals to lube them as you put them back in. now reassemble the softener in the reverse order.
