My central heating system works fine except that when the heating or hot water is switched off by the programmer the pump continues to run constantly. I have replaced programmer and 3 port valve without any improvement. I guess that the pump should run for a number of minutes after the system turns off in order to cool the boiler but I dont know what controls this. Has anyone any ideas?

Not all boilers have pump overun & the ones that do the pump live is controlled by the boiler. What make is your boiler?
.
The boiler is a Baxi Solo. I've managed to find a manual on the "net", I believe that the main thermostat could be the source of the fault. What do you think?
Thanks for your reply.
