hotpoint WF445A bearing noise?

hi, i have a hotpiont wf445a machine bought may 2005 and it sounds like the bearings have gone. no leaks yet! i have had conflicting advice from a number of sources but most of them seem to think they can make a bob or two out of me but i have changed bearings before on older types myself. i just need some advice on how to enter the machine without disturbing sensors or electrics. many thanks.
