Hi Guys I have had Atag combi boiler for 3 years now and the boilers is working fine in terms of producing ch and dhw. However, when I turn the DHW, for the first few seconds the boiler is making a sound that I can best describe it to be "tok tok tok tok" and then stops after 5 or so seconds.
This only happens on DHW and I have done put a cleaner in and let it run for a week then drained and put inhibitor. I don't think the problem is kettling. I have tried to locate the noise but can't pin point it exactly. I wonder if it could be something related to the water tank in the boiler.
