Newhome Stove EFa600H oven stopped working?

Hi All,

I have the above model of the stove and one day it just stopped working.

The clock is working fine but none of the knobs on the front will do anything. Fan, Light and the grill are not turning on.

I had a look at the back and all the mains cables seem to be intact.

Any advice on how to fix or what could be the problem?
