ariston microgenus. New pcb ! ! !


Postby temps » Sun Aug 09, 2009 9:59 am

Hi guys.
Ariston Microgenus 24 he. Originally showing A 01 error code and continously sparking. Changed pcb. Now no fan, no pump, nothing and showing A 79 error code. Pressing reset does nothing.

Any help appreciated.

A 01 - means ignition failure, as the boiler was sparking/trying to light, the first thing to check is the gas supply, then see if there's power to the gas valve.

What does A 79 mean ??? read the manufacturers instructions.

I was going to google it - but I shouldn't have to. You need to give as much info as possible - plus Ariston's are crap, not many people have them, so no-one knows the fault codes :-) - but I would have checked the gas valve before buying a new PCB.
