We are Snowbirds who bought a house in south Alabama, and here Qct. till May. So, it is only used 6-months each year. I had the panel replaced two years ago. Same problem. I watched the service man, and thought, I could do that. Rather than paying him $230.00 again, I found AppliancePartsPro on the internet, and ordered the panel which cost $131.00. It arrived sooner than expected. I removed the old front panel from the dishwasher, took the door lock mech. off, and installed it on the new panel, along with the old circuit board. Plugged in the ribbon connector, put everything back together, turned the power back on, and it worked! I did all this sitting in a folding chair. I am 75 years old. You could do this!!!
