Vaillant ecoTEC pro 24 - New PCB, F70, can't enter menu to enter #7 DSN ?

[CharlieQB]

Hi all

I've just had a friend who is GS reg drop over and fit a new PCB for me due to an intermittent fault with the old. He told me it would throw up a fault code as I drove him to Heathrow to catch his flight that he was late for.

I don't have a manual and can't seem to find the correct one online to enter the Diagnostic Level to enter the new value of the part! (Number 7 I belive?)

Can anyone give me a clear instruction on how to do it?

thanks in advance

Chas

Sorry to say mate but those are installer level codes and are best left alone if you don't know what you're doing. Bit of a poor show for your mate not to do the whole job also not very responsible if he is gas safe. Best advice I can do is get another Gas engineer to do it properly then he can ensure that everything is working and burning as it should be as you have no means to test it

As above.
It's a pity he didn't have time to commission it.
You need a Gas safe reg Engineer to sort that.

Good advice given.
