Keypad won't respond

Our Kitchenaid Whisper Quiet model KUDM24SEBL keypad stopped responding tonight and is stuck in the "End" mode. Won’t initiate a new cycle. Shows that it locks fine.

I unplugged and replugged it in, but seems keypad isn’t responding.

Should I pay for a repairperson parts and time or give up and just get a new dishwasher at this point. I don’t know the age of the unit since it came with the house which we bought 4 years ago.

Thank you,

Laura
