Hi John how are you?
This is either one of two things here.
1) Please make sure all wire connections are very secure including a good solid ground.
2) The motor has a bad winding that is causing the pump to draw excessive current so over time it will over heat the fuse and cause it to blow.
If this is the case, you need to exchange the pump as it is faulty.
Also make sure the pumps impeller isn't jamming, Make sure you can turn it freely by hand. That's about all there is to this, the direction doesn't matter:-)
I will stick with you but Since this question may continue for some time, if you will rate my service as good or betterbefore you close this window, the system here will allow me to schedule free follow ups with youso your question wont close or time out and you can contact me anytime at no additional cost.Thank youTech Michael
Problem found to be short on lead head to pump. Cut off plug and hard wired. Problem with pressure build up to expansion tank. Think valve needs changing must be passing.
Many thanks john.
