Cheers for your advice..!!!!

They are trying to say that it is a different problem so have asked for another £50 excess when Ive called to report the follow up problem...
Ive got someone coming out Fri, but based on comments looks like they wont have solution as laptop didn't identify the fault......
For cost of parts...
I have a potterton Suprima 40, which keeps tripping out. I have British Gas Homecare, so have had them out 3 times now. They have:
Replaced PCB board
Boiler worked fine for a day or so then kept tripping out and showing red light just as about to ignight
They then came out and replaced...
