Vaillant ecoTec Plus 418 D0 Setting

[Dunbar]

Can't see why you can't at least access the d codes as there are numerous posts re the householders changing the parameters including d.0, it must be relatively simple to do this and allowed by vaillant.
If the boiler wasn't serviced since the extended warranty work (PCB etc) then they should return to fix it and even if it has been serviced except they find something seriously set wrong should still honour the warranty.
Why not, at least, give them a buzz?.

Was trying to avoid another call out, but still have three years left on the warranty so will. re adjusting, I've opened the flap and pressed both top buttons and the screen just lights up. Have a feeling that to get the menu you press both top buttons together and then can scroll though, but don't want to f anything up. That's why I asked in the OP if anyone could guide me through.

Changed setting from Auto to 14kw. Didn't fix it. Changed it back to Auto, turned it on and and it went off like a train. Now I'm really confused. Have a feeling that it won't last.

These Vaillants have a bit of a mind of their own I suspect.
Next time you are in the menu have a look at d.01 the pump overrun time and d.02. d.01 has a default time of 5 minutes and the anti-cycling time has a default setting of 20 minutes but the actual time depends on the boiler flow target temperature, at 65C it is 4.5 mins and at 60C is 6 minutes so presumably as long as the boiler has been stopped for either a total of either 5 minutes or 9.5 minutes then it should fire up immediately on request?.
