Thanks for the feedback Ray.
Not sure if we have the same problem as my boiler doesn't seem to make clicking noise but will check the pump speed anyway.
I will also check other forums to see how they were resolved.
Hi, I am encoutering similar problems with my Ideal Classic NF40.
Did you manage to get it sorted? If so, what was the prob?
Searching through other forums the pcb seems to be the prime suspect.
