Check the Water Temperature
One common reason why a dishwasher may not be cleaning dishes properly is because the water temperature is too low. The ideal water temperature for a dishwasher is between 120 and 125 degrees Fahrenheit. If the water is not hot enough, it may not be able to effectively remove food particles and grease from the dishes. To fix this issue, check the temperature settings on your water heater and make sure it is set to the appropriate temperature. If the water is still not getting hot enough, you may need to call a plumber to have the water heater inspected and repaired.
Clean the Spray Arm
The spray arm is responsible for distributing water throughout the dishwasher and cleaning the dishes. Over time, it can become clogged with food particles and debris, which can prevent it from spinning properly and delivering enough water to clean the dishes. To fix this issue, remove the spray arm from the dishwasher and clean it thoroughly. You can use a toothbrush or a small brush to remove any debris that may be stuck in the spray arm. Once it is clean, make sure it is properly reinstalled in the dishwasher.
Check the Water Inlet Valve
The water inlet valve is responsible for allowing water to enter the dishwasher. If it is faulty or clogged, not enough water may be entering the dishwasher to properly clean the dishes. To check the water inlet valve, locate it on the bottom of the dishwasher behind the lower access panel. Disconnect the water supply line and remove the valve. Inspect it for any clogs or damage. If you notice any issues, replace the valve with a new one. Make sure to turn off the power to the dishwasher and disconnect it from the water supply before performing any repairs.
Clean or Replace the Filter
The dishwasher filter is designed to trap food particles and debris to prevent them from clogging the dishwasher’s plumbing or reaching the spray arm. However, if the filter becomes clogged or dirty, it can restrict water flow and prevent the dishwasher from effectively cleaning the dishes. To fix this issue, locate the dishwasher filter, which is typically found in the bottom of the dishwasher. Remove it and clean it thoroughly under running water. If the filter is damaged or worn out, replace it with a new one.
Use the Right Dishwashing Detergent
Using the right dishwashing detergent is essential for getting clean dishes from your dishwasher. Some detergents may not be strong enough to effectively remove grease and food particles, leading to poor cleaning results. Make sure to use a high-quality dishwasher detergent that is specifically designed for use in dishwashers. Additionally, avoid overfilling the dishwasher with detergent as this can lead to a buildup of soap residue on the dishes. Follow the detergent manufacturer’s instructions for the appropriate amount of detergent to use.
