Hi all
Have an Ariston 24 HE MFFI (I hear some sighing )
It had some ignition problems some time ago, Axx type errors but I got a RGI in and he vacuumed around the sensors in the combustion chamber from what he said. She was fine after.
Anyway that was several months ago.. now we are having problems with hot water (and will be main heating when it goes back on). The boiler lights for DHW and after about 1-2mins the boiler cuts off, water gradually goes cold and then the E33 and E34 errors pop up. If you wait a while or turn off water and wait 2mins it works again.
RGI changed water thermistor and later the flow sensor but to no avail. Then he went said it prob PCB.. I looked at the tech manual and it says about fan and pressure switch. I got him back and he tried new air pressure sensor an I asked him about weak fans, in which he said that is fine.. it didnt seem seezed or anything and boiler still played up when he had cover off.. it also blows out of the flue ok so I am not sure if the fan is a bit underpowering / on-way-out.
Anyhow we are at PCB now so although I have told him they are not £300 which he said they often are (not sure if I would of got billed that).
Seen them anywhere from £100-280
Anyone changed a main board on these.. looks easy enough however after looking at the documentation the 'soft light' and 'maximum pressure' pots need setup and I am not an RGI.. however I could set them to the same as the old board. So how critical are they?
