Ευχαριστώ πολύ με βοηθήσατε πολύ να λύσω το πρόβλημα μου !!!

Ok! Thank you very much!❤

I did the same one, successful one. Thank you

did it ever cut flames again w/o the bumper?

I am currently struggling with an Ariston Genus One 5P3 error. I replaced the gas valve, which was clearly full of dirt and the filter was torn. But the 5P3 error is still present with the new gas valve.

Hello! If you didn't put that small black plastic protection, didn't it give error 5P3? Was that little piece blocking the piston? Or don't let the piston open all the way?

Witam, mam od miesiąca ten sam problem. Pytanie czy po likwidacji "zderzaka" błąd 5P3 powrócił po jakimś czasie?

What do you call a bumper? That little black plastic piece in the piston head? It's like you chose not to wear it!!!! Or did I not understand correctly? I saw that the piston that regulates the pressure had a small plastic piece. In the end I understood that you didn't put it on the assembly anymore.

Hello! after all, you still put the Bumper Little black piece, or not?

PCB board it's the problem for all Ariston Alteas / Genus One gas boilers .

Do you know the fix for fault 503 flame sensed with gas valve closed

What product do you use to clean parts?

Did you put it back or not? Thank you!

You silver problem or is still there and you need to fix the pcb part.
