Indesit IDE750 dishwasher Code d0n

I will try and help with this problem with your Indesit IDE750​ dishwasher

You have given me a very limited amount of information​ if your Indesit IDE750​ dishwasher​ ​ ​that will not ​start.  You either have a problem​ with the door lock mechanism, the on-off start button​ or maybe there is no water going into the machine. But you will have to give me much more information for me to be able to assist you correctly. I have included some videos below on Indesit dishwashers
