Thank you for that info. I would then suspect the main push button switch.
This part you need is the main control board , the one with the push button.
It is easy to fit, with just a few basic hand tools and I will help you get to it once you have the new one.
The best place to get that would be: http://www.ransomspares.co.uk/
Its best to call them because you want to make sure to get the correct part the first time;-)
And there are many different boards.
