Our dishwasher went kaput after many months of beeping at weird times. We had luck cycling power from the electrical box which brought it back to life for a short spell.
A few videos made repairing the issue look doable, so I ordered a new control board at the local appliance store. Made for a great reason to get out of the house and take a drive to Walnut Hills. My only regret is not timing it with lunch as there are some good options over there.
Now said board sits on the counter until I gather gumption and tools.
