Hotpoint WD420 won't turn on after cutting out ?

I pulled out my washing machine to clean out filter as not pumping out water properly. got loads of stuff out of it and put back together. after a few small tests i put in full load. it let out water but the pump hadn't been put back right. re-did it and tested machine with wet towels i use to mop up. i put it on fast spin to get rid of excess water on them only for it to cut out! i tried switching it on and off at plug. it came on then but cut out again.Am not sure if it actually did manage a spin though. now it does nothing!! any ideas would be appreciated
