D/W won't cycle auto but will manually

Set my Kenmore dishwasher (dial) to start. Just sits with no dial advance. Can manually start and move through cycles but it will stay on whatever cycle I stop at and not advance automatically. Timer problem? Runs fine in the cycles just won’t automatically progress through the cycles.

Thanks for any advice/help.

No doubt the timer is bad and has to be replaced.

Good luck.
Gene.
