hi you will need to replace the diverter valve ( its a pig to do ) anyway the company you need to speak to is european spares tel 01684773737 also before you buy one just check that all the pipes will come off the hot water heat exchanger, because mine did not so i also replaced that at the same time. any other problems just email me on aliandys@tiscali.co.uk and i will try to help you as much as i can.
good luck
