The Circulation pumps are of the permanent split capacitor vintage, which do not produce alot of heat when starting(or running for that matter), and as a result do not have alot of starting tourque, so a dry pump seal (such as in a unit seldom used or being stored a long time) is more than adequate to cause the motor not to start. This can usually be cured by "freeing" the stuck seal - use of rinse aid seems to aid in keeping the seal free.
