A new challenge. We have a Remeha Tzerra Ace - wall hung gas

Customer Question

Hi all, a new challenge. We have a Remeha Tzerra Ace - wall hung gas boiler - showing an error code I cannot find online. Any advice on meaning and resolution could be great. Error = E04.10I have no idea how to use it, but my partner has conducted a reset. Thanks in advance.

Please could you tell me the G.C. number of your Remaha boiler?

Not sure where that is, but it's 24C

Tricky to call as I am in Serbia

OK. E04.10 probably means that the boiler has detected 5 unsuccessful burners starts. This could be caused by one of the following:

1. No gas supply;
2. Gas valve faulty;
3. Ignition transformer failure;
4. Ignition lead or earthing fault;
5. PCB faulty.

Ok - no idea, which. Anything we can do to reset or restart?
Expert:  Tim Cooke replied 14 days ago.

Power off the boiler, wait at least 10 seconds, and power on again.

It would be interesting to know if the boiler goes into ignition and you hear any clicking, or whether it fails without sparking.

Well, we think we have determined an absence of gas supply. Will update. Thanks!

That would be the least costly outcome :-)

I shall await your news with curiosity...
