Common Causes Of Poor Cleaning
Poor cleaning in an Amana dishwasher can be frustrating. Several common issues often cause this problem. Identifying these causes helps fix the issue quickly. Below are the main reasons your dishwasher may not clean well.
Clogged Spray Arms
Spray arms push water to clean dishes. Over time, they can get clogged with food or hard water. This blockage stops water from reaching all dishes. Clean spray arms regularly to keep water flowing freely.
Dirty Filters
Filters catch food particles during washing. If filters become dirty or blocked, water cannot flow properly. This reduces cleaning power and leaves dishes dirty. Clean filters every few weeks to maintain good performance.
Low Water Temperature
Water must be hot enough to dissolve grease and food. If the water is too cold, cleaning results drop. Set your water heater to at least 120°F for best results. Check dishwasher settings to ensure proper heating.
Improper Detergent Use
Using the wrong detergent or too little can cause poor cleaning. Some detergents do not work well in certain water types. Follow the detergent instructions exactly. Use enough detergent for the load size and water hardness.

Step-by-step Cleaning Tips
Cleaning your Amana dishwasher regularly keeps it working well. Dirt and food bits can block parts inside. Follow these simple steps to clean key areas. This helps dishes come out spotless every time.
Removing And Cleaning Spray Arms
Take out the spray arms carefully. Rinse them under warm water to clear clogs. Use a toothpick to remove stuck debris from holes. Make sure water flows freely through all openings. Replace the spray arms securely before running the dishwasher.
Cleaning The Filter
Locate the filter at the bottom of the dishwasher. Remove it gently and rinse with warm water. Use a soft brush to scrub off trapped food particles. A clean filter improves water flow and cleans better. Put the filter back properly to avoid leaks.
Checking And Adjusting Water Temperature
Check your water heater’s temperature setting. It should be between 120 and 140 degrees Fahrenheit. Too low water temperature can leave dishes dirty. Adjust the heater to reach the right heat for better cleaning results.
Using The Right Detergent
Use detergent made for dishwashers only. Avoid using regular dish soap as it creates too many suds. Measure detergent according to your dishwasher’s instructions. The correct detergent amount helps remove grease and food stains effectively.
Quick Troubleshooting Checks
Quick troubleshooting checks can help fix your Amana dishwasher not cleaning issue fast. These simple steps often solve common problems without needing a repair call. Start with easy inspections and basic fixes. Save time and get your dishwasher working well again.
Inspecting Door Seal And Racks
Check the door seal for cracks or damage. A worn seal lets water leak, reducing cleaning power. Clean the seal with a damp cloth to remove dirt. Also, inspect the racks for broken or bent parts. Damaged racks can block water spray and stop dishes from getting clean.
Loading Dishes Correctly
Place dishes so spray arms can spin freely. Avoid overcrowding the dishwasher. Large items should not block the detergent dispenser. Face dirty sides of dishes toward the spray jets. Proper loading helps water reach every dish and improves cleaning results.
Checking Water Supply
Make sure the water supply valve is fully open. Low water pressure reduces dishwasher performance. Inspect the inlet hose for kinks or clogs. Clean the filter screen at the hose connection. Good water flow is essential for effective cleaning.
Running A Cleaning Cycle
Run an empty cycle with dishwasher cleaner or white vinegar. This removes grease and mineral buildup inside the machine. Regular cleaning keeps spray arms and filters clear. A clean dishwasher works better and lasts longer.

Unusual Noises Or Leaks
Loud sounds or water leaks are signs of trouble. Strange noises might come from broken parts inside. Water leaks can cause floor damage quickly. A technician can find the source and stop the problem safely.
Faulty Pump Or Motor
The pump and motor move water during the wash. If the dishwasher stops mid-cycle or won’t drain, these parts could be damaged. Repairing or replacing a pump or motor is complex. Trust a professional to handle this safely and well.
