If my items on the top rack are not drying would replacing the heater be the logical first option.
Answer Hi Linda. You have to use a thermometer at your sink water to make sure it is at least 120 degrees or higher,(the hotter the better). Make sure your rinse aid dispenser is full. It will normally take the first 10/12 washes to properly coat the inside's of the entire inner walls,racks and motor spray arms for you to notice a change. Rinse -Aid part is readily availible at the local Wallmart or Wallgreens, CVS pharmacies. Please try this first. Is the dishwasher bringing up any fault codes? Thank you.
