How Do You Fix A Dishwasher That Will Not Drain
These are the most common causes of a blocked dishwasher. However, in some cases, there’s a more serious issue, and clearing the filter/hose doesn’t help the water go down. If this is your case, Jake believes that ‘something may be jammed in the dishwasher. To fix this, you will need to disassemble the bottom of the dishwasher, vacuum out the contents of it, and ensure that the parts are moving as they should. However, this process can be complicated, so I’d recommend calling a professional appliance technician.’
Remove And Clean The Filters
Blocked filters are a common cause of dishwashers not draining, but they’re easy to check and fix.
You’ll find the filters in the bottom of the dishwasher they come in three parts and are very easy to pull or twist out. Remove, clean and replace the filters. If you use your dishwasher regularly, its a good idea to clean the filters every week or so. You can do this by running them under the tap.

How A Dishwasher Drains
The dishwasher is connected to a drain hose that runs water into the pipes under or into your sink. Sometimes the plumbing connections in your sink begin to deteriorate and need to be replaced, or there may be excess debris clogging the bottom of your unit. When you have a problem with a dishwasher not draining, youll see water and even bits of food at the bottom of it.
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.

Understanding The Parts Of Your Dishwasher
Before I get into how to fix standing water, its helpful to know about the parts of your dishwasher and to have a basic understanding of how dishwashers work.
Dishwashers often have the same types of parts, but they may vary based on the manufacturer.
Here are some common parts Ill mention in this article:
Air Gap: An air gap, also known as an air cap, is a device that prevents dirty water from re-entering your dishwasher, ensuring that the water used to wash your dishes is clean. Not all dishwashers use an air gap however, some states plumbing codes require it.
Dishwasher Filter: Depending on the manufacturer, you may have a manual or self-cleaning filter. This filter is usually located on the bottom of the dishwasher, but your owners manual will have exact details. Its purpose is to catch food and other debris during the wash cycle to keep the recirculating water as clean as possible.
Drain Hose: This is a hose that connects the dishwashers drain pump to your garbage disposal or air gap.
Drain Pump: This part pushes water from the dishwasher into your drain line or garbage disposal.
Spray Arm: This part rotates and shoots water onto the dishes during the cleaning cycle.
Not sure which parts your dishwasher has and where they are located?
Thankfully, you can access detailed product manuals online for your specific dishwasher brand and model.
Below are links to the manuals for the most popular brands:
The Lifespan Of A Dishwasher
Rick Carbajal, owner and operator of Bluffton, South Carolina-based NuWay Appliance, LLC, says that the typical lifespan of a dishwasher is three to five years on average, but with any major appliance, issues can arise over time. With your dishwasher in particular, these can include control board failure, wash pump issues and draining mishaps, all of which can become quite expensive to repair. Sometimes, its more cost-effective to purchase a new dishwasher if the issues are too prominent.

Your Dishwasher Wont Pump Because The Sink Is Clogged
It may not be something you immediately think of, but a clogged drain could be the reason water is staying in your dishwasher. When your drain is clogged, there is nowhere in your kitchen for water to drain away, which is why water in the dishwasher also stays. The problem may be with the dishwasher drain hose, or it may be with the main drain under the sink. Finally, you should also be aware that your dishwasher will not drain if the control panel is stuck. If, for example, the on/off button is stuck, it will start a new program each time while the old one is still running.
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:

Check The Sink’s Air Gap Cylinder
An air gap cylinder keeps water flowing in the right direction during the dishwashers cycles. It also prevents wastewater from backing up into the dishwasher. It should be located behind the sink and near the dishwasher outlet hose.
Check the air gap cylinder to make the inside is clear. If you notice any buildup, clean it out and make sure its tightly secured.
Tips To Keep Your Dishwasher Draining Properly

- Always turn on your garbage disposal prior to running the dishwasher to clean out food and debris in the system.
- Dont use drain cleaner in the dishwasher. Chemical drain cleaners like Drain-O or Liquid Plumber should never be used because of their caustic ingredients that can damage rubber parts of the dishwasher.
- Make sure youre using the right type of dishwashing detergent. Use only powder, liquid, tablet, or pod detergent specifically designed for automatic dishwashers.
- Check that youre using the right amount of dishwasher detergent. Homes with soft water require about a quarter cup of detergent . Hard water areas require a full cup of detergent for a good wash.
- Perform annual maintenance on your dishwasherthis includes cleaning the filter and trap with a stiff brush and hot, soapy water, cleaning the spray arm holes with a stiff wire brush, checking the dish racks for cracks, checking the drain hose clamps to ensure theyre properly clamped, looking for leaks and cracks in the door seal, and making sure the pre-heating mechanism is functioning properly.
- If you think theres an issue, address it quickly. Letting the problem sit can make the clog worse and may cause additional repairs. If the cost of a potential repair is holding you back, the cost of a home warranty may be more manageable. Warranty premiums are $25$67 a month, and you only pay a nominal service fee any time you have a repair for a covered appliance.

Jake also recommends baking soda and vinegar for dirty dishwashers with grimy filters: ‘Dump 1/2 cup to a cup of each into the drain of the dishwasher. Let it sit for a while and work its magic for 15 minutes to half an hour, then flush it down with some hot water.’

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.

Check The Drain And Valves

Perhaps your dishwasher wont drain because of a problem with its drain or check valve. A dishwashers drain valve is an electrical part that may have a visible, movable bracket or arm. This is accessible by removing the units front panel and placing it on the floor.
The bracket should move easily. However, it may be frozen in place or otherwise jammed. If you can free it up manually, that may solve the problem. If it wont move, however, the problem could be electrical, and a new valve may be needed.
A check valve is a mechanical element that allows water to pass in one directionout of the dishwasherbut not back in. It can be a small flapper or ball at the beginning of the drain tube, right past the drain valve. A check valve can become stuck, and will either need to be reset, freed up, or replaced. Access to the check valve is also through the front of the unit.
