Can I get spare parts for an older machine?

I have an Indesit WG1130T washing machine and the broard grey rubber seal that goes around the inside of the door keeps getting mouldy so that I have to bleach it every time I use the machine. I wondered if there is any way I can get a new seal delivered and fitted? Would it also be possible to obtain an instruction maual for this model as it was given to me and I do not know how to use it fully to its best.
