Mend Ariston Micro Genus

How can I fix my ariston micro genus he 32 mffi boiler?

The boiler is just over a year old and out of warranty-the pressure keeps rising and I have to bleed the radiator down more than twice a day to keep it below 3. I'm worried about a pipe bursting or something exploding!

Oops-sorry, meant to say 'by' a level of 11-1.5 daily not to! It keeps going up-I drain it down to about 1 and by morning it's up to 2 and by evening it's at 3 which is why I'm having to drain the radiator.

Hi Craig

The pressure reading depends on whether I have just drained the radiator down-usually between 1 to 1.2 and when the heating is on, it used to go up to about 2.0 when the boiler was working properly. Now, the pressure keeps increasing to a level of about 1-1.5 bar daily.
I'm also only using the heating for about 2 hours first thing in the morning.

Hi Liz

What is the pressure reading when the boiler is cold and turned off?. It should be 1 bar to about 1.2 bar. When the boiler has been fired for about 15-30 min would expect pressure to be about 1.8-2.0 bar.
