Why would my worcester 28i junior keep blowing fuses?

Hi, for some reason my worcester 28i junior boiler started to blow fuses (the first one which is 2amp). It does it when i either press any of the buttons on the front of the unit or even when i turn the water on!!! Please help as i am left without any means of having a bath and i cant stand showers all the time. Thanks very much.
