I recently had this happen to a fairly new pb-4 that ran dry and overheated for about an hour before I noticed it. I disassembled the volute and impeller on the front of the shaft to look at the condition of the impeller and shaft seal. There are several youtube videos that detail the shaft seal replacement. I ended up having to replace the impeller as well as the shaft seal due to the impeller being deformed. Cost me about $35 for both the impeller and seal.
