If your dishwasher is not cleaning dishes properly, you might be surprised to discover what may seem like a broken dishwasher is a simple case of knowing how to clean your dishes differently. From cloudy glasses to a salty taste, food residue and stained cutlery, hereâs the top problems that people encounter when using their dishwasher and how best to solve them.

How Do You Fix A Dishwasher That Is Not Cleaning Dishes

If you have been having trouble with your dishwasher not cleaning your dishes correctly, it may be due to a faulty part. The most common parts to fail that may cause your Whirlpool dishwasher not to clean are:

  • Water intake valve The water intake valve is responsible for bringing water into the dishwasher. If this valve is clogged or defective, the dishwasher will not be able to get the water it needs to clean the dishes.
  • Faulty washer arm assembly If the washer arm assembly is not functioning properly, the dishwasher may not be able to spray water on all of the dishes, leaving them dirty or unwashed.
  • Defective circulation pump A defective circulation pump may prevent your dishwasher from washing dishes properly. This pump is responsible for circulating water through the dishwasher. If it is defective, water will not reach your dishes during the cleaning cycle, leaving them unwashed.
  • Broken wash impeller A dishwasher impeller is a small plastic blade that circulates water into and through the dishwasher arms. If the wash impeller is broken or missing one or more of its fins, it will not force water through the dishwasher arms correctly.
  • Drain pump motor failure A dishwasher drain pump motor helps to pump water out the drain. If this drain pump is defective, it will not be able to move the drain properly, and your dishes will not get clean.

Easy Ways To Troubleshoot Dishwasher

Regular maintenance and cleaning of the dishwasher can avoid any possible problem. If your dishwasher isnt cleaning the dishes well, it must be because of an underlying cause that you need to locate and address. Here are some troubleshooting tips to help you cope with a dishwasher that doesnt clean well.

1- Clogged Spray Arm

If a clogged spray arm is jeopardizing your dishwashers ability to clean, take it out of the dishwasher. If its a new dishwasher, the spray arms will come off easily. Soak spray arms in hot water for at least thirty minutes, then poke its holes with a thin steel wire or a toothpick to remove the blockage. Scrub it with a soft brush and rinse with hot water. Let it air dry and then install it back.

2- Dirty Filter

If you have a new dishwasher, it most probably contains a manual filter. To clean it, remove the filter from your dishwasher and soak it in hot water having dishwasher soap. Let it sit for 10 to 15 minutes, gently scrub the filter with a soft brush and rinse it under hot water. let it dry completely before putting it back inside the dishwasher.

Heres a detailed guide on how to wash a dirty filter where Ive shared different ways to clean a dishwasher filter easily.

3- Food Residue

4- Failing Inlet Valve

If you hear a hammering voice coming from your dishwasher, your inlet valve is failing. It would require a professional to fix or repair a failing inlet valve. In worst cases, it would be necessary to replace it with a new one.

That your glasses still have fingerprints, that your pots are steadily turning gray, and dishes have bits and specks on them?

    Remove Food From The Coarse Filter

    Dishwasher Won’t Clean Dishwasher Troubleshooting

    The coarse filter is located at the bottom of the dishwasher, and its job is to catch the food particles that could obstruct your drain. Check the coarse filter to see if it has any big food particles or other debris that could possibly be causing the dishwasher to not clean as well as it should. If you find something on the coarse filter, remove and then try running another cycle to see if that does the trick.

    White Spots On Your Glasses And Dishes

    There is nothing more frustrating than when youâre trying to clean glass and other dishes that continue to come out of the dishwasher with white spots. This is due to the minerals found in hard water. To prevent this, make sure you check your appliances salt levels, top up your rinse aid and use Quantum Ultimate detergents which offer built-in protection against spots and marks while delivering a sparkling shine.

    Please note, these solutions will not protect from mechanical damage or restore already damaged items. If you have tried these tips and your dishwasher still doesnât clean dishes, you should consult a maintenance professional.

    Tip : Clean The Inside Of Your Dirty Dishwasher

    Make it a habit to look inside and see if you have a dirty dishwasher. Once a month isnt too much to ask, right?

    Youd be surprised at what you might find: chunks of old food, glass from broken dishes, popsicle sticks, toys, you name it!!!

    The obvious first step is to check the bottom of the dishwasher for debris. The mat-like thing you see is called the coarse filter and is meant to catch big particles that could prevent your tub from draining.

    Feel around with your hand in areas you cant see and remove the cover to the reservoir where the water drains. Reach down into this reservoir and take out any food or other muck. Yes, this is gross but you have to do it for the sake of mankind .

    There was a plastic popsicle wrapper in my reservoir along with some other items that I wont mention. Sure Im a little embarrassed but this is life.

    If these large bits are just floating around in the dishwasher water they can certainly be sprayed back onto the dishes, which defeats the purpose of having a dishwashing machine!!!

    There is also a fine filter in your dishwasher. It looks like a circular spaceship that has fine mesh sections to it. Clean off the mesh with a sponge or run it under hot water. Our fine filter had what looked like coffee grounds on it.

    Again, this is the stuff that could be sprayed back up into your cups or dishes. So cleaning the fine filter should be on your to-do list every month.

    Why Is My Dishwasher Leaving A White Film On Everything

    Tip : Remove And Unclog Spray Arms

    Clogged spray arms have to be the #1 problem we encounter with our dishwasher. Its a function of the hard water we have here in Pittsburgh and the new non-phosphate dishwasher detergent.

    We have a stainless steel GE Cafe dishwasher with SmartDispense technology. The SmartDispense concept seemed like a good idea. You could dump in a ton of liquid dishwasher soap and not have to worry about manually filling up the soap cup every time dishes needed to be cleaned.

    When we started using the SmartDispense dispenser the directions were followed and the correct soap was used. Then soap manufacturers changed their formulas and eliminated the use of phosphate. Which was good for the environment but bad for our dishwasher system.

    The two different kinds of soap caused residue or scale to buildup in our dishwasher. Theres a good chance you have the same problem.

    If your dishwasher is like our GE brand then you can remove the lower spray arm by turning it counterclockwise and pulling up at the same time.

    Remove the top & middle spray arms by using a ratchet and appropriately sized socket, which was 1/4 inch for me.

    Heres a brief video to help you with removing your spray arms

    Check all of the holes in your spray arms for clogs. You can use three different methods to remove debris from the holes.

    You can also use a wire hanger, the cheap kind you get at the dry cleaners, to unclog the arms.

    The next step will help neutralize any crud you missed with the wires or cables.

    Problem With Dishwasher Water Supply

    How to Repair a Dishwasher Thatâs Not Cleaning Dishes

    The dishwasher requires the proper amount of water at the right temperature and pressure to clean optimally.

    Check these water supply issues when you notice your KitchenAid dishwasher not cleaning dishes well:

    • Water not hot enough: A dishwashers water temperature should be at least 120 to clean sufficiently. You may need to raise the temperature of your homes hot water heater to improve dishwasher performance. Running the hot water in your kitchen sink before starting a wash cycle can ensure that its readily available to the dishwasher.
    • Water pressure too low: The water inlet valve requires at least 20 psi of pressure to open, allowing water to flow from your home supply to the dishwasher. If the water pressure is too low, the valve wont open to supply the dishwasher with enough water. If possible, increase your homes water pressure so the valve can function properly.
    • Part failure: In other cases, the water inlet valve may be broken, restricting the dishwashers water supply. Spray arms are also prone to cracks and malfunctions that limit water access. These parts must be replaced for the dishwasher to function correctly.

    Dishwasher still not cleaning as it should? A professional dishwasher repair service should have a look. Schedule an appointment with one of our expert technicians to solve the problem!
