The boiler reqs to be pressurised to 1 bar in a cold state, in operation the heat expansion with cause the gauge to rise by about half a bar so in full working mode with heating on you'll expext the gauge to register around 1 1/2 bar-

Sorry Terry - I'm not used to this site! Question was - anyone know what the error message E34 means on an Ariston Boiler MicroGenus 24HE please?


The information I have found states it is a problem with the pressure switch. A faulty pressure switch will prevent ignition from occurring. Here is a Youtube video link showing the issue. Reading the comments below may assist you in isolating your problem. Hope this helps!

Moved in house Monday & have a radiator leak due to bad rust...what's best temporary repair to hold for a few weeks b4 plumber available? What sort of Boiler is Ariston Genus 24 mffi ?


turn both valves off at each side of radiator and once the pressure balances it will stop leaking, there is no solution to this whilst using this as a radiator to heat the space, but will stop the leak.

Ariston microgenus 27 pressure on 0


Filling loop is underneath the boiler, easily identified as a chrome coloured braided pipe with a black tap at either end. Open right hand tap first then left hand one . Fill system till presure gauge reads just over 1 bar when system is cold. Then turn both taps off.
