leak through impeller seal.

removed spray head, pulled motor/pump assembly. took apart impeller housing and then removed motor and pulled impeller off its shaft, the most difficult part was actually pulling off impeller from the splined shaft. I actually broke old impeller in the process. The good thing is that the new seal came assembled with new impeller so that was not a problem. After re-assembling everything it worked fine and still works for a week since repair.
