A bit involved but quite straightforward.
Open the grill door and you will see 4 screws on the underside of the hob - remove the inner 2.
You can now hinge up the entire hob.
On each side of the hob is a trim piece with 2 screws which retain the glass front panel. Remove these and the end trims.
Carefully pull the timer buttons away from the fascia - the simply click into position.
The glass panel can now be tilted up and removed - it is pocketed at the top.
Each of the control knob assembly can then be easily pulled away from the controls.
The fluorescent tube is situated below the controls in a recess.
Rotate the tube through 90° and lift the tube out.
Refitting is the reverse of the above procedure.

Normally the 720ef is the oven, the hob is a separate unit and in my case is a STOVES 600G gas unit. Your unit may have a built on hob but the handbook for the 720ef does not detail this. In my case the hob ID is on the lower right hand side of the unit.
I think you will find that the elements may have failed but you will need to identify the hob to ensure correct replacements. Normally the element rating is on the base of the element. The handbook will tell you how to take the thing to pieces. It is possible that the hob element controls have failed but unlikely for all three or it may be a combination of both parts. I think you may have to contact an electrician to test everything to sort this out.

Hobs

On the underside of the hob (any oven or hob situated underneath the hob may need to be removed to gain access.).

The hob is normally totally independent of the oven. What is actually working or not working on the oven? i.e. does the grill still work, is the clock OK and can you set it, or is everything totally dead?

There are possibly a number of options. It could be that in wiring the hob in you have disturbed the wiring for the oven. Normally the oven works off the main oven control switch on the panel and the hob could be wired into something else.
Is the oven totally dead no power at all for everything, or is the clock running but the oven will not switch on?
