Samsung dishwasher not draining

Why is my Samsung dishwasher leaving water in the bottom?

When your Samsung dishwasher isn't draining, start with the simplest checks. Blockages from food particles, debris, or other obstructions in the drain pump filter, garbage disposal, air gap, or drain hose are common reasons for this issue. The position of the drain hose might also cause a problem with draining. Addressing these problems can often get your dishwasher draining properly again without needing a major repair.

Check for Food Particles and Debris

Food particles and debris can easily cause dishwasher drain problems. These can build up at the bottom of the dishwasher tub or clog the drain pump filter, preventing water from draining away.

• Inspect the Bottom of the Tub: Open the dishwasher door and look for any visible food debris or particles around the sump area. Remove any buildup with a paper towel or cloth.

• Clean the Drain Pump Filter: Locate the drain pump filter, usually found at the bottom of the tub. You can check your owner's manual for its location. Remove the filter and rinse it under running water to clear out any food particles or debris. Make sure to securely reinstall the filter before running another cycle.

Check the Garbage Disposal

A clogged garbage disposal is another common reason a dishwasher won't drain. Dishwashers are often connected to the garbage disposal, and if the disposal is blocked, water won't drain properly from the dishwasher.

• Run the Garbage Disposal: Turn on the garbage disposal to clear any waste that may be blocking the drain path. Run water into the disposal for a few seconds after it stops to ensure the drain is clear.

• Inspect for a Knock-Out Plug: If a garbage disposal was recently installed, make sure the knock-out plug in the drain pipe connection was removed. Follow the manufacturer’s instructions to remove this plug if it is still in place.

Check the Sink Air Gap

An air gap, installed on some kitchen sinks, prevents drain water from backing up into the dishwasher. If the air gap is clogged with debris, it can cause draining problems.

• Inspect and Clean the Air Gap: Remove the air gap cover and check for any clogs. Clean out any debris using a small brush or rinse it with water. Securely reinstall the air gap cover.

Check the Drain Hose

The dishwasher drain hose must be installed correctly to ensure proper draining. If the hose is kinked or if there isn't a high loop, it can cause water to back up into the dishwasher.

• Inspect the Drain Hose for Kinks or Blockages: Check the drain hose from the dishwasher to the sink or garbage disposal for any kinks or visible blockages. Straighten any kinks you find.

• Verify the Drain Hose Loop: Ensure the drain hose has a loop that is higher than the drain connection point. This high loop prevents water from siphoning back into the dishwasher. Adjust the hose if necessary to create the proper loop.

By following these steps, you can often resolve draining problems without needing professional help. If these checks don’t solve the issue, consider more advanced troubleshooting or contact a professional technician.

Advanced Troubleshooting for Dishwasher Draining Problems

If the simple checks haven’t resolved the issue and your dishwasher still won’t drain, it may be time for more advanced troubleshooting. This could involve checking for deeper clogs, a malfunctioning drain pump, or even electrical issues. Here are some steps to consider:

• Check the Dishwasher Drain Hose for Clogs: If the hose was previously inspected for kinks, it’s time to look deeper. Disconnect the drain hose and inspect it for clogs or buildup that might not be visible from the outside. Clear any obstructions before reconnecting it securely.

• Inspect the Drain Pump: The drain pump pushes water out of the dishwasher. If the pump is faulty or obstructed, it won’t function properly. Access the drain pump and look for visible obstructions or signs of damage. If the pump is damaged, it may need to be replaced.

• Examine Electrical Components: Sometimes, a control board or wiring issue can prevent the dishwasher from draining. Check for any loose wires or burnt connections that might indicate an electrical problem. If you are not comfortable checking these components yourself, it’s best to call a professional technician.

Samsung Dishwasher Water Not Draining

When water is not draining from your Samsung dishwasher, follow these troubleshooting tips to fix the problem:

• Check the kitchen sing drain to see if it’s clogged. Clear that clog if water isn’t draining from the kitchen sink.
• If the dishwasher drain hose is connected to the garbage disposal under your sink, run the garbage disposal to clear food from the disposal to dishwasher water will drain freely through the garbage disposal.
• If you recently installed a new garbage disposal under your kitchen sink, make sure the garbage disposal knock-out plug for the dishwasher drain connection is removed. Knock out that plug if it wasn’t removed during garbage disposal installation so the dishwasher will drain properly.
• If you have an air gap installed in the dishwasher drain line at the kitchen sink, clear that air gap if it’s clogged.
• Place a bucket under the drain hose connection to the garbage disposal or kitchen sink drain and pull the dishwasher drain hose off the connection under the sink. Check for grease or debris clogging the dishwasher drain hose. Remove the clog if you see one at the end of the dishwasher drain hose. If you suspect an internal clog in the dishwasher drain hose, try to suck out the clog using a wet/dry shop vacuum.

If these basic troubleshooting tips don’t help your resolve the problem with your Samsung dishwasher water not draining, schedule dishwasher repair service and we’ll send an experienced Sears Home Services technician to your home to fix the appliance.
Standing water in your Samsung dishwasher post-cycle often means a blocked drain or defective pump. Stagnant water can mold quickly, compromising future loads. Rather than manually emptying it each time, look into dishwasher service near me. Efficient draining returns your dishwasher to odor-free, effective washes.
