I agree totally with docspock. Your contract is with the retailer, not the manufacturer. Manufacturers often give guarantees of varying lengths but that is just to improve brand image, it is not the law. The law says that goods should last "a reasonable time", and less than two years is not reasonable for a washing machine in my opinion.
Read up on the Sale of Goods Act, quote some bits at them and threaten them with the small claims court. That usually works.
I have successfully done this with a laptop battery from Dell (gave up the ghost after 13 months - the guarantee was 12) and a DVD recorder from House of Fraser after 18 months (again the guarantee was 12).
