KitchenAid Dishwasher Not Cleaning? Check These First

Before you call

1. Clean the filter

   Newer KitchenAid units use a removable filter instead of a hard-food disposer. If nobody has ever cleaned it, that is likely the whole problem. Twist, lift, rinse, replace.
2. Spin both spray arms by hand

   They should turn freely. Then hold them up to the light and check the holes — mineral deposits and soaked-off label residue block them, and a blocked arm leaves whole racks untouched.
3. Stop pre-rinsing quite so thoroughly

   Modern detergents need some food residue to work against, and these machines read soil level to choose a cycle. Spotless in, spotty out is a real pattern.
4. Check the water is hot before you start

   Run the kitchen tap hot first. A dishwasher that begins with cold line water spends the early part of the cycle just heating it, and shorter cycles never catch up.
5. Look at how the load is stacked

   Tall items in the lower rack block the upper spray arm. If the top rack is consistently dirtier than the bottom, that is usually the cause rather than a pump.

When it's time to call a technician

If the filter and arms are clean, the water is hot, and it still won't clean, the circulation pump, the wash motor, or the diverter is what gets tested next. Worth noting: Seattle-area water is soft, so a heavy white film here is more likely detergent residue or permanently etched glass than scale — mention it when you call, because it changes what we look at.
