powermax155

[tina13]

I have a 11 year old powermax155. no. 1 The problem is no hot water, just lukewarm or cold . no. 2 There is also a hammering noise when the toilet is flushed.
Any advise/ help with diagnosis and solving the problems would be appreciated. Thank you

This is seen as a difficult boiler and has safety implications after someone was killed by one a few months ago.

There are several possibilities as to the cause but the usual advice would be to recommend that you get a competent boiler engineer who is happy to work on your model.

Probably the dhw pump or the blending valve.

I don't do toilets!
