Please can anyone help? My boiler central heating wall switch was worn out and wouldn't fire up the boiler. I resorted to putting on both the central heating and hot water switches on at the same time so that the boiler fired up. Shortly after, the hot water when hot will shut the system down and the radiators will cool after a brief period. Now when I switch on the boiler instead of firing up it starts making very violent rattling noises and I immediately switch it off! Do you have a clue what the problem might be.

Thanks for your reply Ollski. I'm not well versed re boilers etc but a boiler engineer has told me that he thinks the circuit board needs to be changed. What's the relationship between the circuit board and the pump? or header tank. Can I change these parts myself?

The old ones were about £96 plus fitting and the latest type is about £160 plus fitting ( which is more involved ).
The old ones were rather unreliable and the new ones are meant to be better!
We would charge our fixed price diagnostic charge of £84 plus the cost of the part and that includes a service and system check.
