The agitator is not moving or the motor sounds strained.

Possible Causes:

The packing nut may be too tight. For proper tightening, see DELTA Service Procedure 001.

The packing assembly may have corrosive buildup. If periodic maintenance was ignored, and acid solution was allowed to leak into the packing assembly, the shaft may become immobile. Inspect the packing set and the agitator for corrosive build up. Contact ANKOM to determine if the packing set and agitator need replacement. DELTA Service Procedure 001 describes replacing the packing set.

The motor stopped turning. Check the packing nut to make sure it is not overtightened. See DELTA Service Procedure 001.

The motor needs to be replaced. See DELTA Service Procedure 023.
