how close is the boiler to the downstair outlets ?

have you checked the plate heat ex ?

 

[aa_minasian@hot]

it is too close. The problem is this system was fine and for more than 4years. And it started just 2 days ago

If hot water is fine down stairs it wont be the boiler. Is it a bath tap by any chance

I'd check thermistor, p heat ex and diverta mate
