[Back to Automatic Dishwashing Problem Chart]

Problem Causes Solutions Preventive Measures
Small particles (food or detergent) left on items Water not reaching surfaces, dishwasher overcrowded. Check to be sure water action is not blocked by dishes. Check filter for accumulated or deposited food or detergent. Load dishwasher correctly. Keep filter clean.
Water temperature too low. If your dishwasher does not have a heat booster, run the hot water at the kitchen sink for a few minutes before turning on the dishwasher. This will clear the line of cool water. Run dishwasher when other household demands for hot water (such as for laundry or bathing) are low. Same as solution.
Insufficient water fill. Water pressure may be too low. Do not use water for any other purposes when dishwasher in in operation.

Check service manual for water pressure recommendations or call appliance service company.
Same as solution.
Powder detergent stored too long or under adverse conditions. Use powder detergent within one to two months after purchase. Open one box at a time. Always close pouring spout after each use. Store in a cool, dry place. Same as solution.
Rinse agent supply depleted. If dishwasher has a built-in rinse dispenser, add liquid rinse agent. If no rinse dispenser, add solid form. Same as solution.
