I have one of these but the central heating is not working. Its about 10 years old. Had problems with the pump which screamed at me when using hot water. Is there a particular part I need.

Thanks.

Diverter valve failure?

Fixing a boiler requires diagnosis which usually has to be done at the appliance!

Thank you. Have been down this road. Have now put in a new mother board do you think that will be the answer. Understand that mother boards go pretty quick had one put in about 9 months ago

Thanks

Is the boiler pressure gauge indicating more than .75bar?

Thanks for your help. My plumber did not look at the timer for the central heating before he took it all part and still could not find the problem after three or four days. Needless to say i will not be using him again.
