There can be several reasons why your dishes may come out of the dishwasher with spots or streaks. Here are some common causes:
Hard Water: If your home has hard water, it contains high levels of minerals like calcium and magnesium. These minerals can leave behind spots or streaks on your dishes. Consider using a dishwasher detergent that is specifically formulated for hard water or using a rinse aid to prevent mineral deposits.
Improper Loading: The way you load your dishes can affect how well they are cleaned. If dishes are stacked too closely together or if items block the water spray, it can result in spots or streaks. Ensure that dishes are properly spaced and positioned so that water can reach all surfaces.
Insufficient Rinse Aid: Rinse aid is a liquid additive that helps to prevent water droplets from forming on your dishes, resulting in spots or streaks. If you're not using rinse aid or running out of it frequently, consider adding more to your dishwasher to improve the drying process.
Temperature and Water Pressure: If the water temperature is too low or the water pressure is inadequate, it can affect the dishwasher's performance. The dishwasher needs hot water to effectively dissolve and rinse away detergent. Make sure your dishwasher is connected to a hot water source and check the water pressure to ensure it's adequate.
Detergent Issues: Using too much or too little detergent can impact the cleaning process. If you use too little, your dishes may not be effectively cleaned, and if you use too much, it can leave behind residues that cause spots. Follow the manufacturer's guidelines for the recommended amount of detergent for your dishwasher.
Clogged Spray Arms or Filters: Over time, the spray arms and filters in your dishwasher can become clogged with debris, which can affect the water flow and result in poor cleaning performance. Regularly inspect and clean the spray arms and filters to ensure they are free from any obstructions.
If you continue to experience issues with spots or streaks on your dishes, it may be helpful to consult the dishwasher's user manual or reach out to the manufacturer's customer support for specific troubleshooting tips.
