how do you replace the element in the main oven of an indesit fdu20?

In general, elements will be bolted in from the rear, and have the connections the same place. Not familiar with specific model, but have a look where the ends of the element go to. That is where you need to get to. You will probably see a plate at the end of the element, that is fixed from the other side. The connections will also be there. Make sure you fully isolate before you do anything. High current on ovens. If you do not isolate, death is the other option.
