BAXI 105HE No hot water

[clink]

Thanks for the reply. There is no flashing lights at all. The burner ignites ok on the central heating but as soon as you open a hot tap it goes off.

when you turn tap on and microswitch makes does the hot water neon come on ?

 

[clink]

Yes it does

in that case it sounds like the board did you get any water on it when you changed the diaphragm . They usually dry out ok with a hair dryer on them

Maybe. There was a fair bit came out. It fired up ok to start with then failed. I will get the hair dryer on it tomorrow. Thanks.

I have dried the board with the hair dryer. Now water lights the burner but the flame fluctuates and eventually dies. It is still ok on heating.

Best to get a proper service carried out on the boiler.

Right away couple of issues come to mind that could give those symptoms
