21 errors typically are caused by an issue with the Service station (on the right side where the printhead  parts when not in use). 21.1 errors indicate an issue with the primer motor. The motor is part of the service station and HP does not list the primer motor by itself in the parts list. Check pricing because often a full maintenance kit will be cheaper than replacing just the service station.
