Did you send it to Anovo, Thetford?

Not the cheapest way but suggest you call them.

Good luck. Just so you know: some people were struggling to get a replacement as early as March 2011. However, others were sorted out well into the Autumn.

If discussion fails - Get the most expensive repplacement you can and do the 'ebay-swap'!
