Dishwasher Not Cleaning Dishes Properly
Solutions for dishes that come out dirty, spotty, or with residue.
Troubleshooting Steps
Clean the Filter
Most dishwashers have a removable filter at the bottom. Remove and rinse under running water. Use a soft brush to remove stuck debris.
Check Water Temperature
Water should be at least 120F for effective cleaning. Run the hot water at the sink until hot before starting the dishwasher.
Inspect Spray Arms
Remove spray arms and clear each hole with a toothpick. Food particles and mineral buildup can block water jets.
Evaluate Loading
Ensure dishes face the spray arms. Do not nest items together. Large items should not block spray arm rotation.
Check Detergent
Use fresh, high-quality detergent designed for automatic dishwashers. Old detergent loses effectiveness. Do not use too much or too little.
Fill Rinse Aid Dispenser
Rinse aid helps water sheet off dishes, preventing spots. Check the indicator and fill when low.
Run a Cleaning Cycle
Use a dishwasher cleaner or run an empty hot cycle with a cup of white vinegar to remove buildup.
Check Water Pressure
Low water pressure affects cleaning. If other fixtures have pressure issues, the problem may be house-wide.
