OK, here's a little 'pump primer:'
You need to KNOW what the problem is, or you will get into endless disputes over whether the problem is electrical or mechanical - and no one looks good when that happens.
Blew three fuses? There's the first mistake. Fuses don't blow out of boredom, and you need to check things before you start melting fuses.
Disconnect the pump. Determine what your incoming power is- and confirm that's what it should be.
Megger each wire to the pump, between each other wire as well as to the case. The only 'good' path ought to be the one through the windings. Any short to ground is bad. The windings should show SOME resistance. (You don't need a fancy megger ... a $150 Supro will do what you need).
If the windings are testing as 'open,' look for some control or float that's open.
Are there 'extra wires?' Look up the pump - the internet is great for this - and see if the pump has a built-in thermal overload or leak detection circuit.
Everything checks out as electrically OK, try powering it up- and watch the amps. Are you drawing too many? If so, there's a good chance that something is keeping the pump from turning. Time to pull the pump and check it out. Plumbers' work? Perhaps .... but be there when he is.
