Whirpool Dishwasher not working

The dishwasher started to give me problems. None of the buttons were working. I replaced the microcomputer and is still giving me the same issues. What else can it be?

Most likely the problem is a bad key pad. It comes as a part of the console. Whirlpool has discontinued the white console. So the only black console is still available.
