Dishwasher will not start

All the buttons lit up except start/cancel and delay buttons.I can go thru heavy,normal and light load, tough scrub,high temp wash,sanitize,heat dryed.It was working 2 days ago now it don’t start.And I tried the diagnostic test and nothing,because you have to press the start button and it’s not working.Can anyone help me

Well I think I’m just going to scrap my 5 yr old dishwasher and my wife can go back to the old way of doing dishes.She’s not going to like it, but can’t afford a repairman to fix what I don’t know what’s wrong with it.Well there is a brite side to this,I’m going to save on my electric bill and I can use that money to buy ear plugs so I don’t have to listen to my wife complain about her dishwaher anymore.Thanks to everyone who replied!!!Oh that’s right no one replied.Sorry for this post I have the WIFE breathing down my neck wanting her dishwasher fixed!!! NAG NAG

THANKS AGAIN On my way to the store for ear plugs before she gets home
