See what's happening and how to try the first recovery step.

Inspect Spray Arm HolesRemove both spray arms and check if the small holes are clogged with mineral deposits or food. Use a toothpick to clear each hole.

Check Water TemperatureRun the kitchen faucet hot for a minute, then use a thermometer to ensure water entering the dishwasher is at least 120°F (49°C).

Load Dishes CorrectlyEnsure dishes face the spray arms and aren't nesting together. Large items should not block the detergent dispenser or spray arms.

Use Rinse AidFill the rinse aid reservoir to improve drying and prevent water spots. Adjust the dispenser setting to 3 or 4 for hard water.
