It is a big clue but I'm not sure if the hot water takes longer to come on in general (new info I know). Well my wife claims the hot water from the sink tap wasn't working this morning. It did for me but I must have waited longer for the boiler to do it's thing.

The fact that it works just fine with the shower head off is surely a pretty damned big clue?? I agree, strip it down and sort it, or bin it an buy a new one. |

Well I just ordered a new shower head and hose from Amazon. Should get them in the morning. At least it rules those out if it makes no difference.
But I am still wondering about water flow through the Grohe shower.

New shower head and hose arrived today and now fitted. Made no difference. Time to call the plumber. But at least I've ruled out the obvious.

Which diaphragm? The one in the flow detector in the boiler?

Yes the one in the flow detector - it was stopping the boiler detecting hot water usage unless the flow was high. And the flow through the shower was not sufficient to trigger it.

So we were right in principle but just not in detail. ...

I suspected it was flow detection because other hot taps would start the hot water heating process. And you could trick it to stay on the shower. I did look up how to do it even - but if I did something wrong could have needed an expensive callout for a heating engineer rather than a planned visit, if you know what I mean. The part was probably only a fiver.
