A good friend of mine has a Kitchenaid KUDS01FLSS1 dishwasher with a heating element that doesn’t heat. It was installed about 2003 and has been well cared for and used lightly by him and his wife. Aside from the inoperative heating element it washes fine. Is there an easy way to remove the element to check continuity, or is there another common problem like a relay that would cause this? He would like to repair this dishwasher if it’s not too difficult and expensive.
