Just fixed my 2 year old Hotpoint Aquarius CTD00 thanks to some of the answers I found on here.
Everything appeared to be working apart from the heating element.
I removed a panel at the back, roughly oval in shape covering from the lower left corner to the centre, which had about 10 screws.
I then removed the internal bracket which holds the heating element and thermostats.
One of the thermostats has a small hole in the top, into which I inserted a pin and heard a click.
Reassembled it and it now appears to work fine.
