My Bosch Worcester 280 shuts off the boiler after 20 secs of running the Hot Water tap. The CH shuts off after about a minute or so.
This just started this morning.
As I watch it after turning on the HW, the pilot flame ignites then the main burner, then 20 seconds later they both shut off.
Very occasionally this year the Overheat has tripped but I don't think that's relevant, however!!!
Does anyone have any ideas
