Baumatic BDW16 keeps fusing out?

Hi I've had this for over a year and had the E4 for a while which cleared following your wonderful advice - but now it keeps fusing out when I try to switch a programme on - it will switch on ok - and then blows the fuse box when I touch the programme button or 1/2 load button .. any ideas what would be causing this as really can't afford a call out fee at the moment and really missing my dishwasher??
