Will I Need A New Dishwasher If It’s Not Draining

Not necessarily. In the vast majority of cases, a clogged filter or drain hose is to blame, and your dishwasher should be running normally after you’ve cleaned those parts of the machine.

Using your dishwasher correctly is also important. Jake’s advice is: ‘Always be sure to rinse plates and dishware before loading them in the dishwasher to increase the longevity of the unit without problems. Also, be careful about what you put down the kitchen sink, as grease can accumulate and cause problems for anything else draining through the same line.’

The Filters Are Dirty

If your dishwasher wont drain, the first thing you should do is check your filter. Filters are an integral part of a dishwasher and need to be maintained to keep the machine running efficiently. Filters trap soggy food particles and prevent excess food and grease from being redeposited within the dishwasher.

However, filters can easily become blocked if they are not regularly cleaned. We recommend cleaning your dishwasher filters at least once a fortnight to avoid dirty plates and ensure your appliances longevity. Luckily, cleaning your filters is a simple enough task.

Firstly, youll need to locate and remove your filters. These are found at the bottom of the dishwasher, below the lower spray arm. Begin by twisting the cylindrical filter to release the filter from the dishwasher.

Once the cylindrical filter has been removed, it is then possible to lift the metal mesh filter plate. Have a quick look in the sump, the lower pit located underneath both filters, to check that no large food deposits have fallen into the sump area and are causing a blockage.

To clean the filters, youll need to run them under the tap to wash away any food deposits or built-up grease. For extra tough grime, you may want to use hot soapy water with a sponge or even an old toothbrush. Simply replace the filters within the dishwasher once they are clean and grime-free.

Solution : Unclog The Air Gap

Not all dishwashers have an air gap, but if yours does, theres a chance it has become clogged with debris, which can cause water to back up in your dishwasher.

How do you know if you have an air gap?

Its a small cylinder usually located near the sink and is often plastic with a protective metal casing. Heres an example:

If you dont see anything like that, you can skip this section.


  • Disconnect power to the dishwasher and garbage disposal.
  • Next, remove the casing and the diverter, a plastic cap that covers the air gap.
  • Remove any food particles. You may need tweezers or needle-nose pliers.
  • Use a small tube or pipe brush and warm, soapy water to clean the inside thoroughly.
  • If there are clogs deep in the air gap, you may want to feed a slim drain snake through the air gap until you see it appear in the garbage disposal area. That way, you know the entire pipe is clear.
  • Reassemble the air gap, restore the power, and run the garbage disposal.
  • Next, run a wash cycle without dishes to see if the problem is still present. If you still have water pooling in the bottom of your dishwasher, try another solution.

    Check The Garbage Disposal

    Why Won

    In most cases, the dishwasher drain hose connects to the disposal. When there is food built up inside the disposal or when the disposal is clogged, there is less space for the dishwasher water to flow. Run the disposer thoroughly with plenty of water running to clear it out. This may fix the drainage problem with the dishwasher.

However, if there is too much water that leaks onto the floor when you open the door, then that should worry you because it is an indication that the dishwasher is not draining water properly as it should.

    The Door Isnt Shut Completely

    Like most appliances, a dishwasher cannot start a cleaning cycle if the doors are not fully closed and latched. The doors must be closed so that the washer does not leak or spill water while cleaning, keeping things neat and safe in the kitchen.

    Most models nowadays have sensors that help ensure that the doors completely close, trimming down possible causes of non-closure to capacity overload, improper loading, or defects and malfunctions.

    How to fix a dishwasher that doesnt drain due to sensor detecting irregularities? Always make sure that everything is carefully and properly loaded and that the racks are properly aligned.

    Inspect for any damage, obstruction, or defect on door components such as springs, hinges, the gasket, and the strike plate and have them repaired/replaced accordingly.

    Also, check that the sensor is working if you see that your dishwasher doesnt drain.

    The Reasons Why Your Dishwasher Wont Drain Water

    Why is My GE Dishwasher Not Draining?

    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.

    What Causes Whirlpool Dishwasher Not Draining

    As mentioned earlier, the major reason behind whirlpool dishwasher draining is the clogged dishwasher filter.

    When you donât clean or forget to clean your filter, food particles can build inside, causing drain issues. If there is no problem with your whirlpool dishwasher, there should be something else.

    If you are trying to figure out the issue, you have to inspect your dishwasher correctly. Here are some common problems that are likely to create drainage issues on the whirlpool dishwasher.

    Check The Sink Disposal

    The interior parts of a garbage disposal system are usually housed within a dishwashers body.

    While theyre of independent function, unfortunately, clogged pipes of sink disposal can and will affect proper drainage.

    Check the disposal unit itself and be rid of any stuck chunks of food and other biodegradable waste.

    Also, inspect the connecting pipes and make sure that theyre clear of debris and leftovers.

    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 theres 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 : Deep Clean The Garbage Disposal

    Most dishwashers dont have a dedicated plumbing line. Instead, they connect and drain through the garbage disposal, which is connected to the outside drain pipe.

    If you dont run your garbage disposal often, or you dont clean it frequently, food and debris can build up and prevent water from properly draining out of your dishwasher.

    Look into the disposal with a flashlight and give the area a sniff.

    If you see buildup around the disposal blades or smell a pungent odor, a clogged disposal could be causing your issue.

    As a first step, run hot water and then turn on your disposal to make sure it is clear of food matter.

    Then, run a dishwasher cycle to see if that fixed the problem. If not, follow the steps below to deep clean your disposal.


  • Turn off the power to your garbage disposal by unplugging it or switching off the circuit that powers it in your electrical panel. Even after cutting power, try turning it on to make sure it is completely disconnected.
  • Use a flashlight to look down into the disposal. If you see objects that need to be removed, use tongs. Never put your hands in the disposal, even with the power off.
  • If you see buildup on the disposal blades, place two cups of ice into the disposal and a half-cup of rock salt.
  • Restore power to the garbage disposal, turn on the water, and let the disposal run for one minute.
  • As it fizzes, use an old toothbrush to clean the inside of your disposal gently.
