    Drain The Standing Water

    When you have water sitting at the bottom of your dishwasher, youll need to manually drain the standing water from the dishwasher. To avoid making a gigantic mess, start with laying down old towels on the floor underneath the dishwasher. Listen, its still going to be messy, but the towels will help soak up water and minimize the mess.

    Once the towels are down, use a ladle to collect the water from the bottom. Deposit the water into a sink, a toilet, or if you want, a bucket. After scooping out as much water as possible with the ladle, soak up the rest of the water with more old towels and rags.

    Assess The Drain Hose

    Dishwasher drain hoses become corroded by hard water buildup or simply obstructed by food debris. They can also become kinked. Badly damaged hoses should be replaced.

    If your drain hose is otherwise in good shape, you can unclog it yourself.

    Disconnect power from the dishwasher and remove the front panel. Disconnect the hose from the drain pump and check it visually for clogs.

    Remove any blockages with compressed air or hot water and a wire. You can also replace it with a new one if the clog is impossible to remove without damaging the hose.

    How And Why Dishwasher Clogs Occur

    He points out that many people think that following a hearty and satisfying meal, they can just clean up and handle the dishes by tossing them in the dishwasher, something that can cause serious problems down the line. Carbajal points out that the name dishwasher is somewhat misleading, but it is important to acknowledge and remember that dishwashers are actually designed to sanitize dishes, not wash them.

    Some individuals are not very avid about properly rinsing your dishes, so therefore theyre gonna collect more food in the dishwasher, says Carbajal.

    He also explains that it is this food buildup that can collect rather quickly and easily at the bottom of the dishwasher and consequently inhibit proper draining of the unit. This is actually not what they want to hear, but I usually tell customers, you practically have to washor rinse off very wellyour dishes before loading them into the dishwasher, even if theyre advertised with a food grinder or disposal system, says Carbajal, who adds that taking a bit of time to perform this step prior to operating your dishwasher can go a long way to prevent any draining issues down the road.

    In addition to preserving the integrity and functionality of your dishwasher, this important step could possibly save you loads of time and money in the future.

    How To Drain A Dishwasher Correctly

    If you are looking to remove any standing water at the bottom of your dishwasher, heres how you drain a dishwasher.

  • Place newspaper or towels underneath the dishwasher. Make sure theres no spot around or underneath the appliance left uncovered.
  • Get a large ladle spoon or measuring cup to scoop out water from the bottom into an equally large bowl. You can also scoop the water into the sink.
  • When the water is too small to scoop out, use paper or cloth towels to soak up the remaining water.
  • To prevent blockages from happening often, make sure to use the right dish detergent. Most manufacturers will include that information in the owners manual. So, make sure you read that thoroughly before operating your appliance.

    Also, ensure you clean your filter and drain basket often to avoid drainage issues.

    Clean The Drain Lines

    If cleaning the filter and filter screen doesnt remove the water from your dishwasher, try cleaning the drain internally with a mild solution of baking soda and vinegar.

    Do not use commercial drain cleaners, as the highly alkaline solution damages your dishwasher.

    Mix a cup of household white vinegar and a cup of baking soda and pour these into the bottom of the dishwasher. Dont worry if there is still standing water in the bottom of the tub.

    The chemical reaction caused by these ingredients can remove some of the grease and gunk that block the drain. Allow them to sit and work for 20 to 30 minutes.

    If you notice the water is starting to drain, add in a bucket of hot water to loosen the clogs and move the solution further into the drain.

    If Your Dishwasher Isnt Draining Try The Following:

    Check the pump seal.

    If theres just a teensy bit of water in the bottom of your dishwasher, you dont need to worry. You need a little bit of water to remain in the bottom to make sure the pump seal remains moist.

    Check the dishwasher door.

    If its not closed all the way and latched, the dishwasher wont finish draining. Try closing the door, latching it, and running the dishwasher again.

    Check the cycle.

    If the cycle was interrupted, the dishwasher might not have drained. Look for a cancel/drain button or a way to reset the dishwasher. If you don’t see a button clearly labeled on the dishwasher dash, go online and google your dishwasher’s make and model to see if you need to press a combination of buttons to make it drain.

    Check the electrical source.

    Many dishwashers are plugged into an outlet that is controlled by an electrical switch. Make sure you didnt accidentally turn off the electrical source mid-cycle. The switch is often next to your garbage disposal switch and can be easily switched off without you realizing you’ve cut the power to your dishwasher.

    Check your dishwasher drain hose.

    Your drain hose is probably connected to your garbage disposal, which means you could be experiencing issues with the disposal or the drain hose. Check to see if:

    • The drain hose is kinked, preventing drainage
    • The drain hose is clogged
    • The knockout plug is still in place and needs to be removed
    • The drain hose is hanging down or is too long

    You may need a new drain hose.

    To check the drain or pump for clogs, you must remove the filter to expose the drain and the pumpat the bottom of the dishwasher.

    Ill walk you through the steps, but I have to warn you, this solution is slightly more complicated than the others Ive covered so far.

    So, if youre not 100% comfortable with the necessary steps below, get in touch with a professional on Home Advisor.


  • Before troubleshooting, disconnect the power on your dishwasher.
  • Use your owners manual to locate the drain and drain pump. You may have to remove the filter and drain basket to access the drain, but it varies depending on your model.
  • Remove any visible clogs with a straightened wire hanger or a drain snake.
  • Once you have removed what you can, use a mixture of white vinegar and baking soda to remove the remaining debris and gunk.
  • Place a half-cup of baking soda down the drain and then pour in one cup of vinegar.
  • Allow the fizzy solution to sit in the drain for at least 15 minutes.
  • Then, pour hot water down the drain. Note: Chemical products are not recommended because the risk for chemical contamination of your dishes is possible.
  • Once youve cleared all clogs, restore the power, and run a cycle without dishes to see if the problem is solved.

    Clean The Dishwasher Filter

    You may not realize that your dishwasher has a filter, but most do, and it can quickly get clogged with food debris, water deposits, and bits of garbage. Regularly cleaning the filter, which is located at the bottom of the dishwasher, can help prevent clogs. Consult your manual and our dishwasher filter guide for helpful tips, especially if you are removing the filter for the first time.

    If there is standing water in your dishwasher, use a wet vac to siphon any excess water before removing the filter. Once you have removed the filter, simply hand wash it in warm, soapy water. An old toothbrush can also help remove any hard-to-clean spots. Rinse thoroughly under warm running water. Do the same if your dishwasher has a secondary filter. Let both filters air dry before placing them back in the dishwasher.

    Can I Use Drano To Unclog A Dishwasher

    It can be tempting to just chuck some Drano inside your dishwasher and hope for the best. Our dishwasher experts strongly advise against this. Jake is emphatically anti-Drano in dishwashers: ‘I would never use Drano in a dishwasher. Drano can break down a lot of materials and can damage your dishwasher. I would never risk it. Instead, you can consider safer alternatives like baking soda and vinegar, or enzyme drain cleaners .’

    David Mason, home solutions expert and owner of The Knobx Company , adds that ‘Drano is a caustic household cleaner that should not be put in a dishwasher. The high temperatures in the dishwasher could cause Drano to explode.’

    Just because a product is easy to get, it’s not necessarily the best product to tackle your problem. ‘There are powerful chemicals in some sink unblockers that, if misused, can be dangerous. Drano is one example of a chemical that is potentially harmful. It’s important to always read the label on these products and follow the instructions carefully.’

    What To Do If Your Dishwasher Won’t Drain

    Easy Fix For Dishwasher That Wont Drain | THE HANDYMAN

    A clogged dishwasher that won’t drain is a relatively common and totally disgusting kitchen issue, but strangely enough the problem might not be the dishwasher itself. Rather, it could be your newly installed garbage disposal.

    If you’ve got an excessive amount of water sitting in the bottom of your dishwasher, the first thing to do is check for blockages in the drain plugs located in the bottom of the dishwasher pan. Chunks of meat or vegetables, pieces of paper napkins and other items can clog the drains and prevent the dishwasher from draining properly. Thats why its important to always scrape dirty dishes clean before loading them into the dishwasher.

    If the drain plugs are clear, check the filter, which is located either at the back of the dishwasher or near the base of the lower spray arm. Clean away any debris you find on or around the filter. If the drain plugs and filter are clear, then move on to the draining tube, which often dumps dirty water into your garbage disposal.

    The top rubber tube drains the dishwasher into the garbage disposal. The port on a new garbage disposal will have a plastic plug inside. If that plastic plug isn’t popped out, then the dishwasher won’t drain and the water will pool back into the dishwasher. Start by unplugging the garbage disposal never work on an appliance while its still plug into the electrical outlet.

    To remove the plastic plug, simply release the clamp holding the rubber tube and pull off the tube.
