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.
Clean Out The Dishwasher Filter
There is a filter at the bottom of your dishwasher. If food particles buildup in the filter basket, it could prevent the washer from draining.
If the filter is dirty, you can use the above cleaning solution and a scrub brush to gently clear blockages. Ensure that the filter screen is clear and that water runs through the basket efficiently before replacing it.
For dried-on food particles that wont come off, you can use a sprayer filled with a couple of teaspoons of baking soda, a few drops of Dawn dish soap and filled the rest of the way with warm water.
The mixture should help you remove any stubborn blockages and keep your dishwasher clean between uses. If you have trouble locating the filter basket, check your owners manual.
It should tell you where to find the basket, remove it, and give the steps for cleaning the filter.

The Air Gap Is Clogged
Solution: Some dishwashers use air gaps to prevent dirty water from backing up and contaminating your dishes. If one gets clogged, it can impact the appliances ability to drain. To tell if your dishwasher has an air gap, look for a small silver cylinder sitting by your faucet. If you have one, check to see if its clogged by removing the top cover and pulling straight up. Then, depending on the design, unscrew or release the tabs on the inner cap. Remove any debris or food buildup that may have accumulated and then reassemble the air gap.
Why Is There Water At The Bottom Of My Dishwasher
Filters, trash disposals, drain hoses, drain pumps, and air gaps can get clogged, resulting in water collecting at the bottom of the dishwasher. When food or sediment accumulates inside these systems, the dishwashers draining mechanism becomes clogged. The problem will be resolved after the obstruction has been identified and the material has been removed.

Fixing A Clogged Drain Or Drain Filter
A clogged drain filter is often the culprit for standing water in a dishwasher. To fix it, you just need to take it out and give it a deep cleaning.
How Do You Fix A Dishwasher That Is Not Draining
To troubleshoot a dishwasher that is not draining, you need to first determine if the problem is isolated in the dishwasher or if it is affecting several fixtures. As I have already mentioned, the dishwasher, garbage disposal and sink share the same drainpipe.
Turn on the cold water on the kitchen faucet and start the garbage disposal. Let it run for like a minute.
Meanwhile, check if water is backing up through the garbage disposal itself or through the dishwasher. If there is water backing up through the garbage disposal or dishwasher turn off the faucet immediately and stop the disposal.
If you do not have a garbage disposal, turn on water on your kitchen sink faucet and again let it run for like a minute. Check if water will start to back up through the sink drain or dishwasher.
When you run a garbage disposal or try to drain a sink and the water backs up through the sink drain or dishwasher, you are dealing with a clogged kitchen sink drain line or garbage disposal. Unclogging any of the 2 will most likely fix the problem.
On the other hand, if both the garbage disposal and kitchen sink drain line are draining normally and you have standing water at the base of your dishwasher, you are dealing with a clogged filter, jammed drain pump impellers or a clogged/kinked drain hose.

Top Reasons Theres Water In The Bottom Of The Dishwasher
Heres a look at the reasons your dishwasher is holding water in the bottom. Some problems you can fix yourself with minimal effort, but others will be a bit more complex. If anything starts to sound a bit outside your comfort zone, make sure to have your plumbers phone number handy.
One thing thats worth trying before you start rolling up your sleeves is to try running the dishwasher for another cycle. Someone might have bumped it while it was running and accidentally turned it off before it was finished.
If that is the case, running it again should finish the cycle and drain the tub. If not, keep reading. Make sure to get the water out of the bottom dishwasher first to complete your assessment.
You can scoop it out with a cup, then soak up the rest with a large sponge. Make sure to lay out towels on the floor in front of your dishwasher before proceeding to avoid making a mess.

Use The Right Detergents
Detergents come in many different forms, including liquids, powders, and tablets. You should always buy the right type of detergent for your machine. Dont use dish soap in your washing machine!
Your dishwasher saves you tons of time and money. You should always keep it clean and ready to use. Use the right products to make sure your dishes dry quickly.
Unclog Or Straighten The Drain Hose
A drain hose is used to drain dishes from a dishwasher. Sometimes, a clog occurs in the drain hose, or the hose gets folded or kinked. This causes a backup in the dishwasher and makes it difficult to clean dishes.
Heres how to fix this issue. This solution requires a comfort level with getting down on the floor and looking underneath your dishwasher and the adjoining sink.
Make sure there isnt any power flowing to your dishwasher. Locate the drain pipe.
Typically, one end is connected to the pump behind the dishwasher, and another end is connected to the disposal. If you cant quickly locate your drain pipe, check your owners manual.
Also, this video shows you an example of how you can locate and remove the drain pipe.
Check to make sure the hose isnt folded or bent. There may be things under the sink that block the hose from hanging freely, if this is the case, then youll need to get an unbent wire hanger or augur.
Disconnect the hose. Use the hanger or snake. Flush the drain hose with a stream of water.
To prevent your drain hose from getting clogged in the future use the high-loop method. Make sure you create a high loop by fastening the drain hose to the bottom of the countertop or to the top of the cabinet.
The highest part of the loop should be 32 inches above the floor. Gravity helps water flow down the drain hose. Water and debris do not normally settle in the hose because of gravity.

Why Is There Standing Water In The Bottom Of My Dishwasher
Your dishwasher drains through a drain hose which is connected to the garbage disposal or directly to the kitchen sink drain line. The sink, garbage disposal and dishwasher therefore share the same drain line.

Standing water at the bottom of the dishwasher is a sign that it is not draining. This is often caused by a clogged filter or drain hose, or jammed drain pump impellers. It could also be caused by a kinked or poorly installed drain hose or a clogged garbage disposal/sink drain line.
If you have a new dishwasher that is not draining, it is very possible that the garbage disposal knockout plug was not removed during installation of the dishwasher. Disconnect the drain hose from the garbage disposal and knock out the plug with a hammer and punch/screwdriver.
To fix a dishwasher that is not draining, start by soaking up the standing water using a sponge. Check if the filter is clogged or the drain pump impellers are jammed.
