What is involved when a service is carried out on a Ecotec 831 combi?

Exactly as a Vaillant trained engineer would do if he was doing by the book using the Vaillant checklist.

Many Thanks

It will say in your installation/user manual what the service should involve. But a service these days often involves the use of a flue gas analyser on the test point and not much else.
