Main combi eco 30 pump overrun

[iceman2010]

Hi, I have noticed recently that when the central heating, set at 60 on boiler, goes off the pump no longer overruns for the period of 3 minutes like it always has. Is this a problem? With the dhw it does the 1 minute overrun still.

Thanks.

I would have thought the pcb would control the pump overrun? They are on the Vaillant‘s I work on anyway.
