Delay start disabled?

I’ve recently been operating this d/w with the facia removed (while awaiting replacement). It has worked fine, but I think at some point I may have disabed the “delay start” option, by pressing some combination of the console buttons:) . This may sound stupid, but there is one more button available with the facia off than on. In trying to do a reset, I might have used the wrong pair…yep, tried pushing them again, no luck. So now there is no delay, d/w starts immediately. Probably a failed switch, but just in case, does anyone know if there is a disbale/enable option for this somehow that I’ve hit accidentally?
