What Causes Standing Water In A Dishwasher?

Standing water in the dishwasher can drive your wife crazy, which can be a good thing. There are many reasons why this can happen.

Standing water in the dishwasher when not in use indicates that there is something wrong with the way the drain hose is positioned.

Nonetheless, we'll take a look at common causes of water in the bottom of the dishwasher:

Clogged Filter

A clogged dishwasher filter is one of the most common issues homeowners have to deal with. It can make your dishwasher run inefficiently and may also shorten its serviceability life.

Water will find its way into the dishwasher filter if it is clogged. Tiny food particles and debris can cause the filter to clog and prevent proper drainage.

It's ideal for checking the filter at least once a month and cleaning it as needed.

How To Unclog Your Dishwasher

1. Pull out the bottom rack

Your dishwasher has a bottom rack that holds dishes and silverware. Remove it so you'll have room to maneuver.

2. Remove the impeller

The impeller is the hardware that spins and sprays water to wash your dishes. Disengage and remove it from its place by loosening its screws.  You should see a plastic locking tab that needs to be popped out.

3. Locate the dishwasher filter

The dishwasher filter is located in the dishwasher filter chamber. Remove the drain filter by twisting it clockwise or counterclockwise until it pops out. There is an indicator to tell you what direction to take.

4. Clean the filter

The common way to clean a dishwasher filter is by giving it a gentle brush.

You can use a toothbrush for this task. If the dirt and grime buildup is thick, you may soak it in a baking soda and vinegar solution to loosen it up.

Clogged Garbage Disposal

Water will also cause water to sit in the bottom of the dishwasher if the garbage disposal isn't working correctly.

When a garbage disposal is overwhelmed with more than what it can handle (for example, bigger chunks of food waste), it will become jammed.

Clogged garbage disposals can also be caused by excessive grease buildup.

How To Unclog

1. Remove big chunks of waste products by hand

Try to remove stuck food particles manually. This will make it easier and faster for your baking soda and vinegar solution to work on hardened dirt and grime.

2. Put some ice cubes

You can also run the garbage disposal with ice cubes to loosen stuck food particles. This serves a dual purpose since the ice cubes potentially sharpen your garbage disposal's blades.

3. Use the classic vinegar-baking soda combo

Sprinkle a generous amount of baking soda. Let it sit for a while, and add vinegar. This combination has been proven and tested over time. 

The baking soda-vinegar solution is very effective in breaking down and loosening up all the gunk in your garbage disposal and every part of your home, including sinks, toilets, tubs, showers, etc.

Let it sit for at least 10 minutes.

4. Boil a pot of water

Remove the screen from the top of your garbage disposal. Now, pour the boiling water into it. Allow it to run. This should remove the loosened debris.

Clogged Drain Hose

The dishwasher hose can often become clogged with food particles, soap residue buildup, and small fragments of broken glass, among other things.

It needs to be cleaned periodically to ensure that it can drain efficiently.

How To Unclog

The best way to clear the hose is to run a snake through the hose. When there is an obstruction, free it up using a brush or tool and scrape it out. Afterward, rinse out the hose with running water.

Clogged Pump

Food particles can build up on the pump and make it ineffective, resulting in the pump not moving enough water.

Detergent can also build up. A clogged pump can lead to many problems, including low water pressure and the wash cycle stopping midway.

Since the dishwasher cannot complete its wash cycle, expect water to settle in the bottom of the dishwasher.

A noisy or erratic pump can signal a foreign object stuck inside or a mechanical component needing service.

You can look at what's inside the pump to see what's going on there before calling a professional for help. Who knows if it's just a corn kernel preventing the pump from doing its job?

How To Clean

Cleaning a dishwasher pump may require you to check your manual for instructions and caveats. This task requires patience because of its level of difficulty.

Before you even think of removing and disassembling the pump, keep track of the dismantling process so you can quickly reverse the steps when it's time to put everything back together.

  6. Can You Use Coke or Pepsi to Unclog a Dishwasher?
