Whirlpool oven FXVM6 tripping RCD

Hi

After I cleaning, I found a very small hole in the bottom of my built-in, fan assisted Whirlpool oven.

Now when I try to turn on the oven or grill, the RCD is tripping.

research is telling me that the element may need replacing but I don;t know how to access it.

Is it behind the fan cover? is it on the bottom (how do I get to it?)

A service manual would be really handy if any one can provide one

Thanks for reading
