Samsung Dishwasher Not Draining: How to Fix It Quickly

Drain pump

If your dishwasher doesn’t seem to be draining properly, the first thing you should check is the drain pump.

The drain pump helps remove water from the dishwasher during the draining cycle. If the drain pump is defective, it won’t be able to remove all of the water from the dishwasher, causing it to overflow.

To check the drain pump, first make sure that there is no debris or food blocking the pump. If the pump is clear, then check to see if the impeller is broken.

The impeller is a small plastic piece that helps move water through the pump. If the impeller is broken, it won’t be able to move water properly and will need to be replaced.

2. Drain sensor

If the dishwasher doesn’t sense water, it won’t start. The drain sensor can become clogged with debris, which will prevent it from working properly.

What is it?

The drain sensor is a safety device that is located in the Dishwasher’s tub. Its job is to make sure that there is no water in the tub before the Dishwasher starts its cycle.

If the sensor detects water, it will send a signal to the Dishwasher’s control board and the Dishwasher will not start.

Where is it located?

The drain sensor is usually located in the tub, near the drain. On some models, it may be located under the dishrack.

How to fix it?

To clean the drain sensor, remove it from the dishwasher and clean it with a soft brush. If the sensor is damaged, it will need to be replaced.

How to prevent it?

To prevent the drain sensor from becoming clogged, make sure to clean it regularly. You can also try using a dishwasher cleaner to help keep it clean.

3. Drain hose

The dishwasher drain hose is installed in the sink cabinet, and it should have a loop to prevent the backflow of water.

If your dishwasher isn’t draining properly, the first thing you should check is the drain hose.

Why does it fail?

If the dishwasher drain hose is kinked, clogged, or otherwise obstructed, it will prevent water from draining properly. Over time, the dishwasher drain hose can become brittle and crack, which will also cause problems.

How to fix it?

If the drain hose is clogged, disconnected, or kinked, it could be preventing proper drainage. Check to make sure the drain hose is properly connected and not kinked. If it is, straighten it out or replace it.

To replace the dishwasher drain hose:

-Turn off the water to the dishwasher.

-Disconnect the old drain hose from the dishwasher.

-Remove the old drain hose from under the sink.

-Install the new drain hose in its place, making sure it is not kinked or blocked.

-Reconnect any connections that were disconnected.

-Turn the water back on and test the dishwasher to see if it is draining properly.

4. Drain line

If your dishwasher isn’t draining properly, there’s a good chance that the drain line is clogged. The drain line is the hose that carries water from the dishwasher to the disposal or sink.

If this line becomes clogged, it can cause water to back up into the dishwasher and prevent it from draining properly. There are a few things you can do to clear a clogged drain line.

First, try running some hot water down the drain to see if that clears it. If not, you may need to remove the drain line and clean it out with a wire brush or other tool. If the line is still clogged, you may need to call a plumber to clear it for you.

How to prevent it?

To prevent your dishwasher’s drain line from becoming clogged, run hot water through the line for a few minutes every week or so.

This will help to break up any build-up that may be starting to form. You can also add a dishwasher drain line cleaner to your monthly maintenance routine. This will help to keep the line clear and prevent clogs from forming.

5. Drain Valve

The drain valve is located near the bottom of the dishwasher and is used to remove water from the tub.

If your dishwasher is not draining properly, it may be because the drain valve is not functioning correctly.

Why does it fail?

Over time, the drain valve can become clogged with food debris or mineral deposits. This can cause the valve to stick in the open position, preventing the dishwasher from draining properly.

How to fix it:

To clean the drain valve, first remove any debris or deposits that may be blocking it. Then, use a toothpick or other small object to clean any debris from the valve itself. If the valve is still not working properly, you may need to replace it.

To replace the drain valve, you will need to purchase a new one from a local appliance store. Once you have the new drain valve, simply remove the old one and replace it with the new one. Be sure to follow the manufacturer’s instructions when installing the new valve.

6. Drain Impeller

If your dishwasher isn’t draining properly, one of the first things you should check is the drain impeller. The drain impeller is a small, plastic piece with blades that helps to move water through the dishwasher’s drainage system.

Over time, this part can become clogged with food and grease, preventing it from spinning freely. As a result, water can build up in the dishwasher and cause it to overflow.

If you think your dishwasher’s drain impeller is the problem, there are a few simple steps you can take to clean it.

First, remove the lower rack from your dishwasher and locate the drain impeller. It is usually located near the bottom of the dishwasher, near the drain.

Once you have found it, use a toothpick or other small object to clear any debris that may be blocking the blades.

If the impeller is very dirty, you may need to soak it in vinegar or another cleaning solution before scrubbing it clean.

Once you have cleaned the drain impeller, reassemble your dishwasher and run a test load of dishes to see if the problem has been fixed.

If your dishwasher is still not draining properly, there may be another issue at play. But in most cases, cleaning the drain impeller will take care of the problem.

7. Garbage Disposal

If your dishwasher doesn’t seem to be draining properly, the first thing you should check is the garbage disposal. If the disposer is clogged, it could be preventing water from draining out of the dishwasher.

The best way to clear a clog is to use a plunger. Just put the plunger over the drain and push and pull the handle up and down. If that doesn’t work, you may need to use a plumbers’ snake.

A plumbers’ snake is a long, flexible piece of metal that can be inserted into the drain to clear away any obstructions.

You can usually find one at your local hardware store. To use it, just insert the snake into the drain and turn it clockwise. As you turn it, the snake will start to push through any obstructions in its path.

8. Check valve

The check valve is located in the drain hose, and its function is to prevent water from flowing back into the dishwasher.

If the check valve is not working properly, it could be the reason why your dishwasher is not draining. To replace the check valve, you will need to purchase a new one from a hardware store.

Steps:

-Locate the check valve. It is usually located in the drain hose.

-Remove the old check valve and replace it with a new one.

-Turn on the dishwasher and test to see if it is draining properly. If not, you may need to call a technician.

9. Drain filter

The drain filter is located at the bottom of your dishwasher.

Why does it fail?

If your dishwasher doesn’t have a garbage disposal, then the drain filter can become clogged with food debris.

How to fix it:

Clean the drain filter by removing it and rinsing it under warm water. You may need to use a toothbrush to remove any stubborn debris. If the drain filter is damaged, you will need to replace it.

Prevention:

To prevent the drain filter from becoming clogged, scrape off any food debris from your dishes before loading them into the dishwasher.

You should also clean the drain filter on a regular basis, even if it doesn’t seem to be clogged.

10. Check Ball

The check ball is a small, round piece of metal that is located in the dishwasher’s pump. Its purpose is to prevent water from flowing back into the dishwasher after it has been pumped out.

If your Samsung dishwasher is not draining, one possible reason is that the check ball is stuck in the closed position. This can happen if there is something blocking the check ball, such as a piece of food or grease. Another possibility is that the check ball itself is damaged and needs to be replaced.

To check whether the check ball is the problem, you will need to remove it from the dishwasher and inspect it. If it is damaged, you will need to replace it. If it is not damaged, you will need to clean it and the area around it to remove any debris that may be blocking it.

Once you have done this, you should reinstall the check ball and see if the dishwasher starts draining properly.

11. Drain Solenoid

The drain solenoid is an electronically controlled valve. It is located in the dishwasher’s pump and is responsible for opening and closing the dishwasher’s drain line.

If your dishwasher is not draining, it could be because the drain solenoid is defective. To test the drain solenoid, first unplug the dishwasher from power.

Then, use a multimeter to test the continuity of the drain solenoid. If there is no continuity, then the drain solenoid will need to be replaced.

How do I replace it?

Replacing the drain solenoid is a relatively easy repair that can be done by most do-it-yourselfers.

To replace the drain solenoid, first unplug the dishwasher from power and shut off the water supply. Then, remove the dishwasher’s lower access panel to gain access to the pump.

Next, disconnect the electrical connector from the drain solenoid and then remove the mounting screws that hold the drain solenoid in place.

Once the drain solenoid is removed, install the new one by reversing the above steps. Be sure to reconnect the electrical connector and tighten all mounting screws before replacing the access panel.

12. Pump and Motor Assembly

The pump and motor assembly are located under the dishwasher. It is responsible for circulating water throughout the dishwasher and then pumping it out.

If your dishwasher is not draining, it may be due to a problem with the pump and motor assembly.

Before you begin, make sure that you have disconnected the power to the dishwasher. You will need to access the pump and motor assembly by removing the dishwasher tub. Be careful when removing the dishwasher tub, as it is heavy and can be fragile.

Once you have removed the dishwasher tub, locate the pump and motor assembly. The assembly may be covered in a plastic housing. If so, carefully remove the housing to access the assembly.

13. Air Gap

An air gap is a physical separation between the dishwasher drain and the home’s water supply.

The air gap prevents contaminated water from being siphoned back into the dishwasher. Many local building codes require an air gap for dishwashers.

If your dishwasher is not draining properly, one of the first things to check is whether or not there is an air gap installed.

Do I need one?

If your dishwasher is connected directly to the home’s water supply, then you will need an air gap. Many newer dishwashers come with an integrated air gap, so it is not always necessary to install one separately.

If you are not sure whether or not your dishwasher has an air gap, you can check the owner’s manual or contact the manufacturer.

14. Timer

If your dishwasher doesn’t seem to be draining properly, the first thing to check is the timer. If the timer isn’t advanced far enough, the dishwasher won’t start the drain cycle.

To check the timer:

-Open the dishwasher door and locate the control panel.

-Locate the timer knob and turn it clockwise to advance the timer.

-Close the dishwasher door and start a cycle.

15. Water Inlet Assembly

The water inlet assembly is the part of your dishwasher that brings water into the appliance.

Where is it located?

The water inlet assembly is typically located on the back of your dishwasher.

How do I know if it’s damaged?

If your dishwasher is not draining properly, there may be a problem with the water inlet assembly. You may also see water leaking from the back of your dishwasher or water pooled around the appliance.

What do I do if it’s damaged?

If you think there is a problem with the water inlet assembly, you should call a qualified technician for help. Repairing or replacing this part can be difficult and you may damage other parts of your dishwasher if you try to do it yourself.

16. Wrong Type of Detergent

One of the most common causes of this problem is using the wrong type of detergent. If you are using a detergent that is not designed for use in a dishwasher, it can cause problems with the dishwasher’s ability to drain properly.

There are a few things you can do to try and fix this problem. First, make sure you are using the correct type of detergent.

There are many different types of dishwashing detergents on the market, and not all of them are compatible with all dishwashers. If you are unsure which type of detergent to use, consult your dishwasher’s manual or contact the manufacturer.

Once you have made sure you are using the correct type of detergent, try running a cycle without any dishes in the dishwasher. This will help to clear out any detergent that may be causing the problem. If this does not solve the problem, you may need to call a professional to service your dishwasher.

17. Water Pump Belt

The water pump belt on a Samsung dishwasher connects the motor to the pump. Over time, the belt can become cracked or frayed, causing the dishwasher to stop draining properly.

Why does it fail?

One reason the belt may fail is if the dishwasher is overloaded and the pump cannot handle the volume of water. Another reason is if something gets caught in the pump, such as a piece of glass or plastic.

Replacing the water pump belt is a relatively easy repair that can be done in about an hour.

How to prevent it:

To prevent the water pump belt from failing, do not overload the dishwasher and be careful not to put anything in the dishwasher that could clog the pump.
