Any advice appreciated
Icon 28t combi boiler. Have to turn hot water fully on to get boiler to fire up (in summer/hot water selection)
The micro switch activated by the head of the diverter valve works ok and fires up boiler when pressed. BUT the diverter head only comes out enough when hot water tap fully on.
I am guessing the diaphragm is split/gunked up and not operating fully at lower pressure
2 questions if so
1. anyone agree or have any other ideas?
2. How big a job to inspect or replace diaphragm. Do i have to drain system or can I just undo the 8 screws on the diverter casing to get at it?
Thanks in advance
