Yes CH and hot water are fine,just this burner noise.Also pressure when not running is 1bar,is that normal.Tried adjusting filling loop but can't free plastic keys
Hi
My Ariston boiler is playing up.When I run the CH i cannot run it on min or 1,it has to be 2 or 3+.If I run it on 1 the boiler is noisy as though the burner is constantly trying to ignite,if i turn it up to 2 this then rectifies the problem.
If I run on 3 then turn down to 2 the same...
