hotpoint wd860 very noisy something stuck? bra wire maybe?

Hi I'm having some trouble with my WD860 hotpoint washer/dryer.At the end of its cycle last night it started making a very loud noise,not heard it before.I think a bra wire may be stuck within the drum area.I have previously removed back panel and accessed the pump to remove coins,hair grips etc when pumped stopped working,but this sound seems to be coming from the drum.I have checked internally and round the seal but nothing.How do I access the drum to check for anything trapped? Also any suggestions to what it could be and where to locate it would be great.Also no error code showing so far and still working for now.Thanks in advance Sarah ;)
