Miele washing machine ?

Hi was just wondering if someone had machanical instructions how to mend my miele W3922 washing machine.
The problem is its out of insurance now and 10 years old so and just started coming up with turn stop cock off error but sometimes it start back up and sometimes ive to wait a few hours and spin it first. It also smells to like something is stuck and going off. My machine has never smelled before and ive used 3 machine cleaners in a month but doesnt get rid of the smell . I was wondering if feathers could of blocked it, it certainly smells like damp feathers like when pillows get wet. Also if i can spin it when it comes up with this error it works again like its removed the obstruction. Please can anyone help or advise thank you! Alex
