Also if the pump wasn't running the boiler wouldn't attempt to fire
thank you very much for your response. Yes, I can hear the boiler trying to light and fan is running. A gas safe engineer has tried to replace the pump with a new one. But the problem is still there. So the engineer install the original pump back. Obviously, the pump works.
The fault was happened when I started using hot water. The boiler shows error A01 just in two minutes, and no hot water. then I tried to reset the boiler, then the boiler can start again, but error A01 frequently appeared, and in five minutes, the boiler completely can't work.
Hi .can you check if the heating runs please
The boiler does not fire although I can hear the ignition, so no water and no heating.
no hot water and no heating.
Hi. It sounds like the boiler is firing and not sensing the flame, then cutting out.change the flame detection probe,also called the flame rectification probe.
Thanks for your answer. However, I can't see any flame. It looks no gas comes out. where is the flame detection probe? thanks.
Actually, I have tested the signal from PCB to the modureg of the gas valve. When ignition, a 2.4V signal output to the modureg (two yellow lines). This means ignition has been detected and the system produces signal to open the valve. However, the signal between the brown and blue lines, output to the gas valve, is not stable during ignition. That is why I ask you how many voltages output to gas valve.
I also wonder if the condense trap is blocked. But I don't know what the condense trap is? where is it allocated? how to clear it? thanks.
how to clear it?
Hi, Following my last question, which you may not be able to answer. But could you answer the following questions:
(1) What is the working voltage of the Fan for Ferroli F28? DC240V or AC 240V 50HZ?
(2) What is the working voltage of the gas vlave for Ferroli F28? DC240V or AC 240V 50HZ?
