Washing bin will not spin?

I have a hotpoint extra large cap washer and after I had to rplace the water hoses and the drain tube (due to leakage from moving) now the bin will not spin during cycle unless i take out all the clothes then it starts and i add them one at a time and it seems to work. Is there something that I need to tighten that is causing this? I really cant afford a repair guy please help!
