Hi Clive, cheers from Italy! After 5 months without having shower at home I can wash again at home! Really thanks man! Really really thanks my man! The specialist said “nothing to do, you have to change it all from the start”. Anyway the first condensator was an old one with like half millimeter legs and I blowed after 15 minutes, now with long legs after one hours, still work, and I hope will continue to do so

If you leave the legs long and bend it away from the transformer it should help as I believe it’s the heat from the transformer which causes them to blow.

It could be the exhaust gas sensor which detects if the gas is burning correctly, somewhere at the top where the fumes exit. Normally if you disconnect the two wires from the sensor and connect them together it bypasses the sensor. The sensor may be defective or the gases are not getting out the flue correctly. Also did you replace the PCB with a new one, or reconditioned? The new version has a new arrangement of components near the part I replaced. If it is reconditioned or used it may be defective.

@Sorcli

6 жыл бұрын

If it is the 24, I found this on a forum but doesn't mean a lot to me as I don't have this model, but it may help you: Hi, I just fixed this fault on my Micro-Genus 24 HE. The A77 fault is quite common on these boilers. Basically the boiler thinks that the sensor is open circuit (broken connection ) or short cicuit (Water across the 2 terminals in the recuperator). It is a safety device to check that the condensate pipe is not b locked and hence condensate backing all the way back up to the flue pipe. First thing to do is check that the condensate is able to run freely from the bottom of the recuperator down the pipe, into the condensate trap and out of the boiler. You do this by taking the rubber hose off the bottom of the recuperator and pouring water down the pipe. It should run out of the grey flexible pipe at the bottom of the boiler. Mine was fine. Next remove the fan and remove the sensor across the two terminals on the side of the recuperator. I think this is just a resistor, so just check it's not open or short circuit. Clean any corrosion off the two terminals and reassemble and test. If this does not fix it then you will need to drain the boiler down un-clip the 2 pipes on the front of the recuperator and remove the 4 screws holing it in place. Remove it from the plastic housing. The metal fins on mine were corroded on the bottom edge and this corrosion was present on the bottom of the recuperator housing and between the 2 metal pins that connect to the sensor on the side of the recuperator. You need to remove ALL the limescale and corrosion and polish with P1200 Wet and dry. I also rubbed the bottom face of the plastic housing with a rag with a tiny smear of silicone grease. It's important not to get this on the face of the 2 metal pins that connect to the external sensor. You know when the bottom face is clean, if when you flick water on to the inside bottom surface of the plastic housing it balls up and will run down to the recuperator exit pipe. Ensure the gasket is in good order as it stops carbon monoxide leaking out of the recuperator. Reassemble and it should work fine. I have not had any more A77 faults since doing the above. NOTE: YOU MUST ONLY UNDERTAKE THIS TYPE OF REPAIR IF YOU ARE A CERTIFIED GAS ENGINEER. Read more: www.diynot.com/diy/threads/ariston-microgenus-24-he-mffi-error-a77.369178/#ixzz57H4gEBKq
