Sorry to hear you are having problems with your Elson Coral E. However, you are by no means alone!
Please check this thread http://www.rainbowquay.co.uk/Forum/index.php?topic=30.msg85#msg85 to see if that takes care of the problem.
If still no joy, any one of the plumbers listed our main site http://www.rainbowquay.co.uk/Contacts.html should be able to help you (we have used Ian Norton for this in the past) – but the only long-term fix may be to get rid of your Coral E altogether…
I hope this helps.
