I have a fixed shower head upstairs, three floors up from Vaillant combi boiler. Water pressure in the house is very low but the shower (only 6 months old) has been fine all winter. Suddenly it has stopped firing up the boiler. If I turn the heating on for a bit before we have morning showers, this seems to help produce hot water although the 'water' light on the boiler still doesn't come on, or goes off during the shower. I had the boiler insurance people come and look at it yesterday and they say it is fine, the diaphragm is still in good order and there isn't a problem with it. All other hot taps in the house are fine and they do fire up the boiler so it seems to be a problem in the shower only - perhaps related to pressure although I don't know why this has suddenly happened. I have cleaned the shower head and it made no difference. I have been advised to think about getting a booster pump suitable for combi boilers but am reluctant to do this unless I know it's going to solve the problem - and the fact that there hasn't ever been this problem before makes me wonder why not!
