How to Fix a Whirlpool Dishwasher Not Cleaning Well

Tired of rewashing your “clean” dishes? Let us help you figure out why your Whirlpool dishwasher leaves dishes dirty with white spots or food particles.

Water Supply Issue

One common reason why your Whirlpool dishwasher might not be cleaning dishes well is that the dishwasher isn’t getting enough water, or isn’t getting hot enough water. If the dishwasher isn’t getting enough water or the water isn’t hot, then the dishes won’t get as clean. There are a few things you can do to fix this problem:

  • Check that there are no issues with the dishwasher’s water inlet valve. The water inlet valve is located on the back of the dishwasher. If there is something stopping the valve from flowing, then the water can’t get into the dishwasher.
  • Make sure that the water supply line isn’t kinked. The water supply line is the hose that supplies water to the dishwasher. If the hose is kinked, then the water can’t get into the dishwasher.
  • Check the water pressure. The dishwasher needs a certain amount of water pressure to work properly. You can check the water pressure by turning on the faucet and seeing how much water comes out. If the water pressure is too low, then the dishwasher won’t be able to get enough water.
  • Make sure the water is getting hot enough. The water needs to be hot enough to clean the dishes properly. You can check the water temperature by turning on the dishwasher and letting it run for a few minutes. Then, open the door and feel the water for a proper cleaning temperature.

Dirty Filter

Another common reason for poor dishwashing performance is a dirty filter. The filter catches food and other debris that can clog up the dishwasher. If the filter is dirty, food and debris can keep circulating and the dishwasher won’t be able to clean dishes as well. To clean the filter, follow these steps:

  • Remove the lower rack and look for the filter. The filter is usually located near the bottom of the dishwasher.
  • Take out the filter and rinse it off with water. If there is a lot of debris on the filter, then you can soak it in a bowl of water for a few minutes.
  • Put the filter back in and make sure it is properly seated.

Hard Water Leaving White Spots

If you have hard water, then that can also be a reason why your Whirlpool dishwasher isn’t cleaning dishes well. Hard water leaves behind mineral deposits on dishes, which can leave white spots. There are a few things you can do to fix this problem:

  • Use a dishwasher detergent that is designed for hard water. These detergents contain ingredients that help to remove mineral deposits.
  • Fill the dishwasher’s rinse aid dispenser with rinse aid, or for a natural option white vinegar can work. White vinegar and rinse aid both can help to remove mineral deposits from dishes.
  • Run a cycle with just water, vinegar, and no detergent. This will help to remove any mineral deposits that have built up in the dishwasher.

Too Much Detergent Leaving White Spots

If you are using too much detergent, then that can also be a reason why your Whirlpool dishwasher isn’t cleaning dishes well. When there is too much detergent in the dishwasher, it can leave behind residue on dishes. This residue can prevent the dishwasher from cleaning the dishes well, and can also leave residue behind. Make sure to follow the usage instructions closely with each detergent.

These are some of the most common reasons for your Whirlpool dishwasher not cleaning well. If you are having this problem, then try one of these solutions. By following this Whirlpool dishwasher troubleshooting guide, you should be able to get your dishwasher cleaning dishes like new again.
