whirlpool ADG8100 6th sense dishwasher not starting?

I have a whirlpool ADG8100 6th sense dishwasher brand new, but haS been stored for a long while.
I have filled salt rinse Aaid & added powder I have power connected & is working because I can see the program details which by repeatedly pressing 'P' I can scroll through the programs.
I have water connected, I have put a couple of litres of warm water into the machine & put some items into the machine in case it case sense if its empty.
Other than scrolling through the porgrams & switching the machine on & off there is no other function working. I am unable to get any of the option buttons to light e.g. type of detergent, multizone etc.
So, my question is whats wrong with it??
