Why Is My Dishwasher Leaving Water Spots?

Hard water is water that has high mineral content. When hard water comes into contact with dishes, it leaves spots or streaks on the surfaces of the dishes. These spots and streaks are usually white or brown in color and can be difficult to remove.

Water spots on your dishes can be caused by several other factors, including inefficient drainage, a dirty dishwasher, or using the wrong type of detergent.

How to Avoid Water Spots on Dishes

If you notice water spots on your dishes after a cycle is complete, there are a few ways to prevent them.

Tips to Prevent Water Spots:

  • Use a dishwasher rinse aid – Dishwasher rinse aids help prevent water spots. Rinse aids are designed to help water bead up and roll off of dishes, rather than sit on the surface and form spots as they dry.
  • Change dishwasher detergents – Some detergents contain phosphates, which can contribute to the formation of water spots. To get rid of water spots, try changing your dishwasher detergent to one that is phosphate-free. If you have hard water, try a detergent that is made for use in hard water.
  • Make sure to regularly clean your dishwasher – Mineral deposits build up in a dirty dishwasher and can contribute to water spots left on dishes. Follow our step-by-step guide below to thoroughly clean your dishwasher.

Why Is There Water in the Bottom of My Whirlpool Dishwasher?

Water in the bottom of your dishwasher may indicate that the dishwasher has a clog or is not draining correctly. If you find standing water in the bottom of the dishwasher, try running the dishwasher while empty on its highest setting for a full cycle to see if it will clear any clogs. If the water continues to accumulate, you may have a stubborn clog in one of the dishwasher components.

How Do You Unclog a Whirlpool Dishwasher?

There are several causes of a dishwasher not draining, including components that are not directly connected to the dishwasher. While learning how to clean a Whirlpool dishwasher, you’ll need to learn how to clean a clogged dishwasher. We’ll review the most common causes and their solutions below.

Tips to Help a Dishwasher Drain Correctly:

  • How to clean a dishwasher drain trap: Pour one cup of vinegar into the dishwasher’s drain trap at the bottom of the wash tub. Add one cup of baking soda to the dishwasher. Close the dishwasher door and let it run on its highest, hottest setting for a full cycle. The vinegar and baking soda can help break up clogs caused by grease, food debris, and built-up mineral deposits.

  • How to clear a clog in the dishwasher drain hose: If you suspect your dishwasher has a clog in the drain hose, first unplug your dishwasher from its electrical source. If your dishwasher is connected to garbage disposal, ensure the power is disconnected from it as well. Then, remove the dishwasher’s kickplate and locate the drain hose. Use pliers to remove any debris or food that may be caught in the hose. Rinse the hose thoroughly with hot water and replace it securely before restarting your dishwasher.
  • Check your garbage disposal for clogs: If your dishwasher is connected to a garbage disposal, it’s important to keep the disposal clean and clear of debris. Oftentimes, the dishwasher and garbage disposal share a drain line. If the disposal becomes clogged, it can prevent the dishwasher from draining correctly. To clean the garbage disposal, pour a cup of vinegar into it, allow it to sit for two minutes, then flush it with hot water while running until the clog clears. As a rule of thumb, always run your garbage disposal to clear it before starting your dishwasher.
  • Ensure the air gap is clear: An air gap is a small hole located near the sink that is designed to prevent dirty water and food particles from draining back into the sink and contaminating the freshwater supply. If your dishwasher is not draining correctly, it may be due to a clog in the air gap. To clear the clog, use a small brush or tool to clear any debris or food particles that may be caught in the hole.

If you’ve tried our tips above, but your dishwasher still will not drain, it may be time to call a professional dishwasher repair technician.
