How can i fix my vokera excell boiler?

The leak is most probably from where the steel hot water demand pin that pushes the DHW demand fulcrum arm exits the brass assembly with the dhw diaphragm in it. A new o ring in screw in fixture is part of the standard service kit, along with diaphragms and other wearing parts. It has mains water pressure on one side and a long travel, it wears and weeps. A completely whooshless boiler is most probably a dead fan. However, you need to find a good corgi man to discover for sure whats up. Vokera would give you the name of a qualified local, or you could take pot luck.
