Check for Blockages:

First, Start by looking for any potential clogs in the drainage system of your dishwasher.

Here, you may check for any food particles or debris obstructing proper water drainage in the filters, drains, and spray arms.

In addition, remove any blocks found during this check. 

Inspect the Drain Hose:

The drain hose inspection is the next step that has to be done. First, Turn off the dishwasher’s electricity, take off the toe-kick panel and then check the hose before continuing.

Yes, the air gap, garbage disposal, or sink drain are all reached by this corrugated plastic tube that extends from the dishwasher’s bottom.

To ensure proper draining, clean and clear the drain hose.

Clean the Garbage Disposal:

You must ensure that the garbage disposal and dishwasher drain hose are connected.

When there is food accumulation or blocks, it restricts the area available for draining.

When you run the disposal with plenty of water to remove any blockages, you can fix the drainage problem.

Check the Air Gap:

No doubt, drainage may occur by the air gap, a small chrome cylinder located on the back edge of the kitchen sink.

So, you can remove the cap and clean the inside of the air gap to remove any blockages.

Also, Inspect the hose that is attached to the garbage disposal as well to make sure it is not clogged.

Make the Dishwasher’s Position in Level:

Further, you can avoid drainage issues with a dishwasher that is level properly.

You can move the dishwasher to a more convenient location to ensure effective water drainage.

Check the Drain Screen:

Check for any possible blockages in the dishwashing tub’s drain screen at the bottom.

The drain screen can become clogged by plastic lids, glass, labels, or pieces of plastic.

Make sure the drain screen is free of any debris.

Clean the Filter:

Well! Filter designs vary throughout all dishwashers depending on different brands.

You can open the appliance manual to learn more about the particular filtration system in your dishwasher.

Further, whether the filter is a screen, is detachable, or is behind the spray arm, clean it.

Use vinegar and baking soda:

You can not miss this step, as it should be done regularly.

Now, Mix one cup of baking soda and vinegar and pour the mixture into the dishwasher’s standing water. Allow around 20 minutes.

If the water is draining or about to drain at that moment, rinse with hot water before starting the dishwasher’s rinse cycle.

That may be sufficient to eliminate any blockages or debris keeping the dishwasher from draining correctly.  

Observe the Sound While your dishwasher is running:

It is also important to detect other problems while your dishwasher is operating.

If it isn’t producing the typical operational sounds, especially if it’s humming or clicking, the drain pump and motor should be to be replaced.

If this happens, it may be time to seek professional assistance.
