5 main reasons of why dishwasher doesn’t clean dishes

If the appliances have stopped working correctly, then cleaning the machine will help to solve the problem. In addition, to maintain the performance of the equipment, regular maintenance should be carried out. But at the same time, the contamination of the device is only sometimes considered the main root of the problem. 

If you’re wondering why does your dishwasher not clean your dishes, here are five common reasons

№ 1: Dirty appliances

If you notice the dishwasher doesn’t clean dishes, most often, the problem is the appliances need to be cleaned. Various substances could accumulate inside it: food residue, grease, soap foam, minerals from hard water and more. In this situation, the first thing to do is to clean the inside of the appliances. Suppose there is only a little dirt inside. In that case, you could clean the inner compartment with vinegar: pour 3 cups of white vinegar on the bottom of the machine and set a complete wash cycle. 

One of the most common problems is renowned – overloading appliance. Overcrowding of racks does not allow proper washing of dishes, since a large amount of them prevents access to water and detergent. Therefore, you should not try to cram as much as possible into the box if there is already no room there. It is better to spend 2 high-quality washing cycles than to wash it all over again.

№ 2: The filter is clogged

In addition, if the dishwasher dishes are not clean, it could also be caused by a clogged filter. Older models of dishwashers (which were manufactured before 2010) are equipped with a unique self-cleaning filter responsible for grinding food particles until they are so fine they can be easily washed away. Modern appliances are fitted with removable filters, which should be taken out and washed from time to time. Find the filter fashionably under the counter. 

Often it is closed with a cover can be unscrewed. To clean the filter, unscrew the cover and take it out. Instructions for this process can be found in the owner’s manual. After that, you need to rinse the filter under running hot water. If food or debris is stuck, you should soak it in water with detergent for a few minutes, then brush and rinse.

№ 3: The sprinkler is clogged

If the dishwasher won’t clean dishes, the problem may be that hard water minerals are deposited in the appliances or the dishwasher detergent has clogged the sprinkler. Many modern models allow you to remove the sprinkler without special tools and wash it with your hands.

Sprinklers are located under or above the shelves for dishes inside the box of household appliances. They are responsible for spraying water during the washing cycle. Nozzles (tiny holes) in the sprinklers can be forgotten over time. As a result, the water pressure becomes significantly lower. It would help if you cleaned the sprinklers to get the technique back to work. 

Depending on the specific model of the appliance, you can unclip the lever or unscrew the screw to get it out. After that, you should clean the nozzles with a soft brush and dishwashing detergent. Also, to thoroughly remove clogs, you should take a toothpick. Afterwards, rinse the sprinklers well under running hot water.

№ 4: The detergent dispenser is broken

If the detergent dispenser has stopped working correctly, the soap may not be dispensed at the right time during the wash, or it may not be dispensed at all. The problem is often a jammed spring on the detergent dispenser door. The problem can be solved with a small brush and cleaning the dispenser and the springs. 

You can also remove debris with a solution of hot water and vinegar. However, if the dispenser or spring is broken, they should be replaced with new ones. At the same time, it is worth inspecting the gasket around the dispenser and replacing it. It would help if you regularly lubricated the gasket with petroleum jelly to make it last longer. 

You should also know what to put in the dishwasher to clean dishes. The dishes can get stained if you use poor quality or unsuitable detergent. In addition, you should stay moderate with the same amount of soap. It is worth correctly pouring a suitable, effective detergent into the dispenser. In addition, you should also use a rinse aid. If your water is hard enough, you should also make sure you have a water softener, so the minerals don’t harm your appliances. 

№ 5: Insufficient Water Heating

The water temperature needs to be 120 degrees Fahrenheit or higher for your dishwasher to work correctly. Some models have a water heater, but if they don’t, it’s worth ensuring the proper temperature water is getting into the machine. You could also turn on the kitchen faucet for a minute before washing, so the appliances get hot water during startup.
