Somewhat late, but may be useful for future searchers - I got my machine looked at by Lynne's Electrical in Walworth Rd. The engineer was helpful and friendly; he showed me the exploded motor in my machine and got the shop to call me with a quote. It turned out it was cheaper to buy a new machine (I checked the price of the part online - they weren't trying to scam me). Lynne's offered a range of machines at competitive prices (again, I checked), talked me through the options, and once I picked a new washer arranged for delivery and installation, which again was done by a friendly and professional engineer. Highly recommended.
