Guys.
I have a Baxi 105E combi boiler. For a month or two I've had issues with my hot water.
I have a good understanding of the boiler and how it works, although no gas engineer I am into air conditioning so know the basics of a heating system.
The boiler preheats the DHW reserve as it should do according to the manual.
When I turn on an outlet I get nothing, warm for a few seconds.
When a hot water tap is on the burner ignites and goes out after 30 seconds, 30 seconds later it reignites. Water temperature is tepid. I don't believe that the water that is preheated gets anywhere close to the tap!
When central heating mode is selected the heating comes on after hot water is no longer called for. The heating works fine.
The HW microswitch is engaged when a tap is open and there is
continuity across it. I also see the diverter valve head operating as I belive it should (I tested with a multimeter and got 240V).
I replaqced the primary heat exchanger aweek ago thinking that this was the issue, obviously not to my expense.
I'm totally lost, any advice would be appreciated.
