Washing Machine Worked For 5 Weeks waiting for parts..

If a fault develops on a new product within 6 months it is deemed by the Sale of Goods Act to have been faulty when sold (it had an inherent fault) unless the retailer can prove otherwise. If they can repair it quickly and it isn't too serious most people would accept a repair but the repair should be done in a reasonable time. The fact that an engineer came out doesn't affect your rights under the sale of goods act. You could try telling them they sold you a faulty machine, which broke down within the first 6 months so consumer law says it was faulty when sold which is a breach of contract. You now feel the amount of time you've been without it is completely unreasonable especially as there is no idea how much longer it might be. If they won't exchange the machine you need to take advice from citizens advice.

The main problem is that it's now been so long that everyone is likely to think the part should arrive any day now so there's nothing to do, and of course it might.
