I have noticed that since the Worcester Bosch engineer put in a new pcb and heat exchanger (into my brand new boiler) there no longer seems to be a pump overrun when the boiler switches off.
At least I think it was after he had been. I also had a new pump fitted by an RGI four days later, who didn't touch the boiler. So my question is, is the wiring for pump overrun in the boiler - in which case it is down to the WB engineer, or is it in the control box, in which case it is down to the RGI. Just another little problem to get sorted
Thanks
