" How do you clean a dishwasher? -- Sharon Smith, Lake Oswego, OR Yes, it does need to be cleaned from time to time. Check the drain for bits of food; use paper towels to absorb debris. Start the empty washer, then stop the cycle when the bottom is full of water. Add 2 cups of vinegar (to remove hard-water buildup) and let sit for 30 minutes. Scrub walls with a sturdy brush and finish the cycle. "^^<http://www.w3.org/2001/XMLSchema#string>
