Dishwasher Not Draining | How to Fix a Dishwasher That Won’t Drain in 4 Steps

If your dishwasher wont drain, the next prossible culprit may be the garbage disposal. Most dishwashers are connected via the drain hose, which runs out to the garbage disposal drain. If your garbage disposal unit contains food sludge, unground food, or foreign objects, neither appliance may drain adequately.

Try running hot water down your sink drain and run your garbage disposal again. This could be what helps get your dishwasher draining again.

If you notice that your disposal is blocked, and these solutions dont work, it may be time to call your plumber.

Here are more helpful tips on safely maintaining a garbage disposal and cleaning your dishwasher.

Why Your Dishwasher Wont Drain

Dishwashers sometimes clog up the same ways sinks and shower drains do, and usually for the same reasons .

Your dishwasher has hoses that connect to both the supply and the drain under the sink. Usually, the drain hose is connected to the garbage disposal, if you have one.

When hoses deteriorate with age, they can kink and block drainage. There may be food or paper debris stuck inside them, as well.

Its easy to tell when your dishwasher wont drain youll open it up when its done running and find the bottom full of mostly dirty water.

How To Prevent Dishwasher Blockages

Keeping your dishwasher in good condition can help avoid blockages. When inserting bowls, plates, and cutlery into your dishwasher you should make sure that all solid food waste has been scraped into the bin. This can help to avoid pieces of food being stuck within the filter or drains of your dishwasher.

Another important maintenance method is to run a monthly clean of your dishwasher using dishwashing cleaning tablets or liquid. These tablets or liquids, run through on an empty cleaning cycle, help to remove grease, limescale, and foul odours from your dishwasher. This should be done at least once a month. Keeping your dishwasher clean, including the seals and the spray arm, can help maintain good working order.

Clean Your Sink’s Air Gap

If you don’t have a garbage disposal, check your sink air gap. It’s a small, slotted cylinder below the sink near the dishwasher outlet hose.

To see if the air gap is the problem, remove it by turning it counterclockwise. Then clean out any debris with a stiff brush. After you’ve removed all the buildup, replace the air gap, secure it, and try running your dishwasher again.

Dishwasher Drain Pump Malfunction

Dishwasher Won

Is there supposed to be water in the bottom of the dishwasher? If the wash cycle is complete, there should never be water remaining. However, a drain pump malfunction can prevent a wash cycle from completing, leaving water in the dishwasher. This pump uses impellers to expel the dishwashers dirty water into the drain hose. When the impellers break or the pumps motor fails, the dishwasher wont drain water and it will remain in the tub.

If the impellers are broken or the drain pump motor shows a lack of continuity with multimeter testing, it cant be repaired. The pump should be replaced by a professional dishwasher repair service.

The Best Solutions For A Dishwasher Not Draining Completely

Once you look at the problems that could cause water not draining from the dishwasher, you are halfway there to fixing the problem. After finding the main problems, it is time to roll up your sleeves and start unclogging the dishwasher drain.

Below are the easiest and best solutions to fix and unclog a dishwasher not draining completely.

  • Remove Food From the Drain

Obviously, if there is food in your dishwasher drain, you need to get it out of there to start draining the standing water at the end of a cycle. To remove the extra pieces of food, use latex gloves or straw to push and pull along the edge of the drain screen.

The drain is usually in the shape of a circle or oval, so make sure you clear out the entire circumference of the drain. This should allow the water to start draining almost immediately. Dispose of any food remnants and watch out for broken glass.

  • Run Your Sink Disposal

You may not need dishwasher repair services for such an easy problem and solution.

Since your dishwasher drain is connected to the drain pipe below the sink basin, this is one of the easiest actions that you can take to unclog the dishwasher drain. If the pipe below the sink is clogged, the water will get backed up into the dishwasher from the clog.

To fix this problem, simply run your sink aerator or disposal. This should empty the dishwasher water immediately.

  • Rotate or Unclog the Air Gap

Check And Clean The Drain Hose

How to Fix a Dishwasher Clogged Up – Dishwasher Won’t Drain

If your dishwasher still seems to be clogged, there may be an issue with your drain hose. If the hose is located behind the dishwasher, you’ll have to pull your appliance away from the wall to access it.

Start by inspecting the hose for any kinks that may be preventing water from draining. If there are obvious signs that the hose is bent, try to straighten it.

If the hose doesn’t show any obvious signs of damage, check for a clog. Place a towel or small container beneath the connection between the hose and clamp to catch water, and then use pliers to loosen the clamp so that you can remove the hose and visually examine it for any clogs.

After looking for signs of a clog, try flushing the hose with hot water and watch to see if the water is flowing properly.

If the hose seems to be clogged, use drain or hose cleaner and follow the product instructions provided to flush out debris. Once you’ve checked for and removed any clogs in the hose, you’ll need to reattach it to the appliance. If the hose is overly clogged with debris, you may want to replace the hose.

If these steps don’t resolve the problem, schedule a repair with an Asurion Expert to help fix the issue.

Air Gap And High Loop

If your dishwasher drain hose does not connect to a garbage disposal, it may connect to an air gap. If you do not have an air gap, the drain hose may be positioned in a high loop underneath the sink. Both the air gap and high loop are designed to stop wastewater from flowing back into the dishwasher during the draining cycle. If the air gap is clogged or the drain hose is not in a high loop position, then water backing up and not draining may be causing the drainage issue.

The air gap is usually a fitting mounted to the sink or kitchen cabinet. The air gap works by sending air into the hose, which eliminates the negative pressure that can cause the discharged wastewater to return to the dishwasher. The air gap can be inspected and cleaned of debris by removing the cover and cap.

The high loop method works by looping the drain hose up so that it is secured just under the sink. Check the dishwashers manual for the correct specifications for your dishwashers drain hose.

Clear Tube Before Air

  • Push a straightened wire coat hanger 10 inches into the small air-gap tube.
  • Set the dishwasher to drain/cancel/reset and close the door to start draining as you move the coat hanger up and down to break up the obstruction.
  • Look for a column of water shooting up three inches above small air-gap tube.

If you don’t have an air-gap up by the kitchen sink, your dishwasher drain hose goes directly into your garbage disposal or your kitchen sink drain. If this is the case, proceed to Step 4.

    Get Rid Of The Standing Water

    You probably discovered a problem with your dishwasher when you found a pool of standing water in the bottom. Youll want to clear that water out so you can start to address the issue. Otherwise, you may end up with large debris in your drain that can worsen the problem.

    You will want to use a wet/dry vacuum to suck up the water. If you dont have one, lay down some towels near the base of your dishwasher and use a cup to scoop the water into a bowl. When the water becomes too shallow to scoop, use towels to soak up the remaining water. Clear out any debris you see sitting on the bottom of your dishwasher.

    How To Fix Standing Water In Dishwasher

    If you notice standing water at the bottom of your dishwasher, a repair may be necessary. However, while there are multiple reasons why the water in your dishwasher wont drain completely, most will not warrant a service call. Before calling a professional to fix the issue, follow these troubleshooting steps.

    Check If The Waste Hose Is Blocked

    If cleaning the filters doesnt fix the problem, check that the waste hose at the back of the dishwasher isnt squashed or kinked if it is, this could stop the waste water from draining away.

    If you have a freestanding machine, you and one other person will be able to pull it away from the wall. You can then check that there’s enough room for the hose to drain properly.

    If you have an integrated model this will be trickier, and would be worth calling in a professional for.

    Solution : Clean The Filterand Drain Basket

    The dishwasher filter and drain basket work together to catch food matter during the wash cycle, preventing contaminated water from recirculating onto your dishes as they are cleaned.

    Over time, they can get clogged with food scraps and soap scum, causing water to back up in your dishwasher.

    The filter and basket are usually located at the bottom of your unit, but use your owners manual to find them on your specific dishwasher.

    Some dishwashers have separate filters and drain baskets, but others have one part that does the job of both.

    As you can see in the picture below, my dishwasher basket and filter are one unit.

    Once you located the filter and basket, take a close look to see if there is any food or debris built up.

    If there is, follow the steps below to clear the blockage.

    Even if there is no visible blockage, its still a good idea to clean the drain basket and filter occasionallydoing so will prevent blockages in the future.


  • First, always cut power to your unit for safety.
  • To clean a drain basket or filter, remove the parts using instructions in your owners manual.
  • Empty the basket and then clean it using an old toothbrush and a solution of warm water and mild detergent.
  • Rinse basket thoroughly to remove the soapy residue and place the drain basket back into the dishwasher.
  • Please note that some filters are self-cleaning.

    If your dishwasher doesnt have a removable basket, clean the filter and simply tend to the area around the drain.

    The Reasons Why Your Dishwasher Wont Drain Water

    I Fixed Our Dishwasher Water Not Draining! Here

    A dishwasher that wont drain water might get your dishes clean. However, the dirty water from the cycle is left to rot in your kitchen. This not only is a hassle because you cant run another load of dishes, but it also is unsanitary.

    Below are some of the main reasons why your dishwasher does not drain. Check the details of each as the first step in troubleshooting your problem.

    • There is Food in the Drain

    Occasionally people might leave large particles of food on the dishes and bowls they place in the dishwasher. This is a big mistake that can result in the drain of your dishwasher getting clogged.

    To identify if this is a problem, open the dishwasher and pull out the bottom tray. If you see food particles caught around the sides of the drain, this may be the problem. You might also want to run your finger along the edge of the drain to see if the drain is clogged and you cant see it.

    • Your Sink Drain is Clogged

    Incredibly, the problem with a dishwasher that wont drain might have nothing to do with the actual dishwasher appliance. Instead, your sink might be to blame.

    The dishwasher in your kitchen has a water release pipe that leads the drained water away towards the sink. This pipe is connected to the same pipe that drains the basin of the sink. If your sink is clogged in the pipe below the basin, the dishwasher will also be clogged and may not be draining all the way.
