My Dishwasher Is Not Cleaning

Dealing with dirty dishes even after a dishwasher cycle? If you’re spotting grease, morsels of food, or mineral deposits in and around your dishwasher and dishes, it’s likely something is preventing your machine from cleaning properly.

Why Won't My Dishwasher Clean

Over time, your dishwasher collects remnants of food and grease left behind on your dishes. As a result, the interior parts of your unit including the filter, spray arm, and soap dispenser will have to work harder during the washing cycle.

You may also want to check the water temperature of your machine and consider any potential water pressure or water inlet valve issues that could be preventing an efficient cleaning process.

Potential Issues

The wiring can be easily damaged by water if there is a leak. If you are regularly cleaning under the dishwasher, there is a high chance that you may have pulled a wire from where it needs to go. All wiring must be in place and in good shape in order for all functions to work properly on the dishwasher.

The control board is the brains of the dishwasher which sends signals to each component letting them know they need to be activated. For example, you select heavy wash and the control board will let the dishwasher know what option was selected and complete the cycles. This goes for any other option as well.

The soap dispenser is the slot where the soap is to be set and is held in place by a door cover. This door cover is then opened when the wash cycle is ran. The door can become easily blocked by overfilling the dishwasher or by bigger dishes blocking it. If blocked, your dishes will still be dirty at the end of the cycle due to the soap not being dispersed.

The drain line is run by a set of hoses that can become easily blocked. This can be due to food or a bend it the hoses. To prevent this from happening, best course of action is to remove food remains on the dishes prior to running them in the dishwasher.

The filter is a component which is in place to filter out food particles and keep them in place at the filter to prevent them from distributing all over the place inside the dishwasher, affecting the cleanliness of your dishes.

The dishwasher can save you a lot of time and hassle by cleaning your dishes for you. But, for your dishwasher to function at its best, it also needs to remain clean. Chunks of food, debris, and minerals can accumulate over time in several places within your dishwasher. This buildup can create leaks due to overflows and will give out a funky smell. Ensure the dishwasher is cleaned properly and even run cycles with no dishes inside to fully clean.

The soap dispenser is a small compartment that holds the detergent in your dishwasher. The dispenser's door can be fragile and may break at times. If the door won't close or gets a crack, the soap can leak out and into the drain before the appropriate point in the wash cycle. Not only will this waste soap, it also means that your dishes won't have the proper amount of soap for washing, which can leave your dishes greasy.

To clean dishes properly, a dishwasher needs a mixture of both heat and water pressure. The water pressure not only ensures that all the dishes get cleaned evenly, it also helps to fight against tough stains and stuck-on food. To reach the proper pressure, there needs to be a clear route from the water supply line into the dishwasher compartment. If there's a clog in any of the lines or the spray arm, the flow of water will be restricted and your dishwasher won't get the water pressure it needs.

The dishwasher has a heating element inside that heats the water it uses to wash your dishes. In order for the dishwasher to perform at its peak, the temperature of the water needs to be hot. The heat helps remove food and grime, leaving your dishes, and the dishwasher itself, cleaner. The high temperatures also help fight off germs and bacteria, giving you your peace of mind when eating or drinking from your plates and cups. If the heating element isn't getting the water hot enough, your dishes won't come out as clean as they should be.

The spray arm distributes the water evenly throughout the dishwasher. It can have small openings and or a bigger opening to let the water through. These openings can become clogged at times and will need to be cleared out to function properly. This is why it is a good idea to remove big chunks of food from your dishes before inserting them into the dishwasher. If the clogs are not cleared, your dishes won't come out as clean as they should.

When you turn on your dishwasher, water comes in through the main water valve under the kitchen sink. It then travels through a hose that connects to your dishwasher's inlet valve. The inlet valve is responsible for controlling the flow of water into your dishwasher. It opens to allow water in and closes automatically to stop the flow of water. If it starts to fail, you'll notice that there's either water leaking on the inside or outside of the valve, or that the valve isn't letting enough water through to the dishwasher. When a valve goes bad, it should be replaced right away.
