I also have a KD14ss dishwasher and I have the same problem , when the weather is hot it works well, but as soon as it rains or is overcast the dishwasher switches on but the program buttons do not work. I have changed the pc board but it is still the same. It works for about a week then starts this nonsense again for about another week . pleaseeeeeeeeeeee we all need help what is the problem. looks like a fault with the KD14ss.
