This error indicates that the unit is unable to turn the valve to the home position at startup. If icing is left in the nozzle block to harden, it can prevent the valve from turning. Remove the nozzle block and then remove the valve. Clean all parts. Put a small amount of vegetable oil on a paper towel. Place the valve on its side on the vegetable oil-soaked paper towel and turn the valve 360 degrees so the outside edge of both valve rings are coated with a small amount of vegetable oil. It is important to use a small amount so that excess oil does not migrate to the valve hole and affect the viscosity of the icing.
