Hi, my name is XXXXX XXXXX I have been in the home improvement and repair field for 20 years. I will be very glad to help you today. Have you tried this site? They should be able to tell you what store locally will have the hose. http://www.wickes.co.uk/page/store
No; actually, they can't help because they say the machine is discontinued. Looks hopeless. Thanks, anyway.
