I have the same problem (rust) i thought it might be the barings i have had it repared although i still have the same problem, however i have not checked the filter etc. there is a solution you can buy from any domestic appliance store that apparently helps to clear the system although i could not tell you what it is called and i am affraid to say it has not helped me. Is there anything else you have tried becasue i am now running out of clothes.

P.S My machine is about 18 months old too and i think it may be a common problem with some machines - how true this is i am not sure.
