Maytag dishwasher won’t start

Lisa Templeton asked 9 months ago
i have an older Maytag that has never failed me until this weekend. All the touch buttons appear to work except the “start” button. When you touch it, it will flash about 3 times and then shuts off. We pushed the cancel/drain button and it went through the process of canceling,so all buttons are not bad. All the other buttons appear to work as I can change it from heavy to normal, heat dry, etc and they are lit up. Any suggestions on what we should replace? The door appears to latch and unlatch fine.
