Why can't you get it going? Your going to have to be more specific.

here is an idea anyway. take the impeller out and the impeller shaft.
check to see that the impeller shaft spin's freeley in the impeller. if not or if there is the slightest bit of resistace then take a knife or something with a good edge and scrape the calcium buildup off the shaft. you can soak the shaft in viniger if you want to be lazy. that will take off the buildup but it may take a little while, like an hour or so.
