Beko Washing Machine making grinding noise when rinse and spinning?

Hi,

My good faithful old washing machine has started making horrendous noises when on rinse (sometimes even when washing) and mostly a high pitch grinding/screaming sound when spinning.

Please could you tell me what it may be (inc what parts I need to order) and how to fix it?

I use it constantly for washing baby clothes. So it's really important to me.

This is a fab website and we fixed my condenser drier through here. Please keep it simple tho as I am a newbie at this and not got a clue about washing machines!

Thanks :)
