Samsung Washing Machine Overflowing? (7 Causes and Easy Fixes)

Samsung Washing Machine Overflowing

An overflowing washer is a nightmare we don’t even wish on our worst enemies. After dealing with a flooded laundry room and potential water damage, you have to troubleshoot your washer and continue with your laundry.

Luckily, we know all the possible reasons why a Samsung washer overflows. Most of the time, it is caused by common laundry mistakes, which you can easily remedy and avoid.

 In our guide, we will walk you through all the steps for fixing a water overflow in a Samsung washer. We will also show you preventative tips and measures to help you avoid this problem in the future.

What causes a Samsung washing machine to overflow?

A Samsung washer overflows when you add too much laundry or too much detergent. Using the regular kind instead of a low-sudsing HE detergent creates excess suds, which may overflow during cycles.

If the water pressure switch, inlet valve, or control board is faulty, an overflow error may also occur.

Fixing Water Overflow in Samsung Washer

To fix an overflowing Samsung washer, make sure you’re using the right detergent and the right amount. Check if the drum is overloaded and reduce it if necessary.

If the issue persists, inspect the water pressure switch, inlet valve, and control board for damages. Then, replace the faulty component.

We made a list of the possible causes of an overflow in your Samsung washer. We also have step-by-step instructions to help you troubleshoot the problem with confidence.

Wrong Detergent

One of the most common laundry mistakes that you should avoid is using regular detergent on your high-efficiency (HE) washer. 

Compared to conventional washers, HE models use lower water levels to clean your laundry. A regular detergent will produce too many suds in low water levels, which may trigger an OE or SUD error code.

Whether you have a front-load or top-load model, your HE washer requires HE detergent, which has low-sudsing properties. 

Samsung doesn’t have specific brand recommendations, but it does discourage the use of natural ingredients, such as baking soda and vinegar. 

According to the manufacturer, you should also avoid cleaning products with these natural ingredients as they can potentially damage the washer.

Solution: First, clean your washer to remove excess suds in the drum. Then, remove any residual detergent in the drawer to prevent another overflow.

Clean the excess suds.

After cleaning up your flooded room, you can troubleshoot your washer and get back to your laundry. Start by getting rid of the excess suds in the drum and on the laundry.

  • Step 1: Wait for the suds to settle in your washer.
  • Step 2: Run a spin cycle.
  • Step 3: Wash the laundry without detergent.
  • Step 4: Take the clothes out of the washer if it no longer has the slimy and chalky film. Then, put them in the dryer or hang them out to dry.
  • Step 5: Run a Self-Clean cycle or manually clean your drum.

Clean the detergent drawer. 

Before running a new cycle with the right detergent, clean any excess detergent in the drawer. It should prevent your washer from producing too many suds and overflowing.

  • Step 1: Turn off and unplug the washer.
  • Step 2: Pull the detergent drawer all the way out.
  • Step 3: Carefully lift the drawer up to remove it.
  • Step 4: Rinse the drawer in warm water. Then, use a soft brush to remove any detergent residue.
  • Step 5: Scrub the drawer opening using a soft cloth or a non-metallic brush.
  • Step 6: Wipe the opening with a dry cloth.
  • Step 7: Align the drawer with the rails and gently push it back in.
Tips:
• Only liquid detergent and softener can be added to the auto-dispensing system.
• Don’t add tablet or capsule detergents in the drawer. Add them directly to the drum.
• To add powdered detergent, remove the liquid detergent cup. Add the product directly to the compartment.

Too Much Detergent

The right kind of detergent will surely get the stains and dirt out of your clothes, but using too much of it will not. If you pour in excessive amounts of detergent, it can lead to excess foam and decreased cleaning performance.

Your washer may occasionally stop to let the suds dissipate before continuing the wash cycle. At times, the foam can get way out of hand and start flowing out of your washer.

Detergent residue can also accumulate in your washer, which promotes the growth of mold and bacteria. As a result, a pungent sewage smell might start developing in your washer, and it can transfer to your clothes.

To prevent your unit from producing excess suds and overflowing, pour the right amount of detergent for your laundry load. Don’t go over the max level even if the brand tells you so. 

Instead, reduce the size of your laundry load, or change the detergent.

Laundry Pods1 per cycle1 per cycle

Solution: Clean the excess foam in your Samsung washer, including its detergent drawer. Then, pour the appropriate amount of detergent for your laundry load.

Clean the excess suds.

Start by cleaning up the excess foam in your washer. Give your clothes a good rinse as well to prevent them from developing funky smells.

  • Step 1: Wait for the suds to settle in your washer.
  • Step 2: Run a spin cycle.
  • Step 3: Wash the laundry without detergent.
  • Step 4: Take the clothes out of the washer if it no longer has the slimy and chalky film. Then, put them in the dryer or hang them out to dry.
  • Step 5: Run a Self-Clean cycle or manually clean your drum.

Clean the detergent drawer.

After getting rid of the suds, clean the detergent drawer and prep it for a new cycle. Just follow our instructions carefully to prevent your washer’s problem from recurring.

  • Step 1: Turn off and unplug the washer.
  • Step 2: Pull the detergent drawer all the way out.

  • Step 7: Reinstall the covers and rotate them clockwise to close.
  • Step 8: Close the detergent drawers shut.
  • Step 9: Run a cycle and check if the washer still overflows.

Too Much Laundry

Overloading is another common cause of overflowing. If you add too much laundry in the drum, your washer can overflow during cycles.

Reducing your laundry load should resolve the problem. After removing a few pieces, you must distribute the clothes evenly and loosely around the drum, so they can spin and get a thorough cleaning.

Solution: To rebalance your Samsung washer and prevent an overflow, follow these steps:

  • Step 1: Turn off the washer and drain the water inside the drum.
  • Step 2: Open the door and check if the drum is overloaded by putting your hand inside the tub. Make sure there’s at least a hand’s width of space between the top of the tub and the top of the load.
  • Step 3: Remove your laundry and check their tags to confirm that they are suitable for the washing machine. Only keep the items that are machine washable.
  • Step 4: Measure the laundry that you want to load into the drum.
  • Step 5: Distribute the clothes evenly and loosely in the tub. Don’t twist and pack heavy items (e.g. sheets, towels, and blankets).
  • Step 6: Refer to your user manual and confirm that the selected cycle is appropriate for your laundry load. Change the settings if necessary.
  • Step 7: Restart the spin cycle.
Tips:
• Check the laundry tags on each item before tossing them in the drum. Only add machine-washable pieces.
• Measure your laundry load to prevent overloading or underloading.
• Don’t wash heavy items on their own.
• Don’t pack or push the laundry in the drum.

Faulty Water Inlet Valve

The water inlet valve connects the hot and cold supply hoses to your washing machine. If this component is damaged, your washer will not fill properly or wash your clothes at the appropriate temperature.

Clogged Water Pressure Hose

A water pressure hose is connected to the sensor that controls the water levels during wash cycles. Over time, the hose and its connector can get clogged with dirt and grime, which prevents your water pressure switch from detecting the water level in the drum.

As a result, your washer may overfill and overflow. Or, your unit may stop filling with water at all.

Removing the obstructions in the hose should fix the problem. Although it’s a quick fix, you’ll still have to disassemble the appliance to access the water pressure hose.

What you’ll need:

  • Thin tool (e.g. putty knife or flathead screwdriver)
  • Phillips screwdriver

Solution: To clean a clogged water pressure hose, follow these steps:

  • Step 1: Unplug the washer and turn off the water supply.
  • Step 2: Unthread the screws on the top cover to unmount it.
  • Step 3: Place one hand right under the cover, and insert a putty knife into the seam to release the locking tabs.

  • Step 17: Reinstall the top cover panel and its screws.
  • Step 18: Plug the washer back in and turn on the water supply.
  • Step 19: Fill the drum with water and check if it still overflows.

Damaged Water Pressure Switch

The water pressure switch controls how much water enters the drum during operations. Once you start a cycle, the sensor sends power to the water inlet valve, which opens and allows water to flow into the drum.

As the washer fills with water, air pressure increases in the hose. This signals the pressure switch to turn off power to the water inlet valve, which stops the flow of water into the drum, preventing it from overfilling and overflowing.

If the pressure switch is malfunctioning, your water inlet valve will continue filling the drum with water, eventually causing it to overflow. Or, it could cause your washer to stop mid-cycle.

What you’ll need:

  • Thin tool (e.g. putty knife or flathead screwdriver)
  • Phillips screwdriver
  • New water level sensor

Frequently Asked Questions

What does it mean when Samsung washer says OE?


A Samsung washer OE code indicates an overflow of water error. It occurs when your washer detects that there’s too much water in the drum than is required for the ongoing cycle.

When it appears, your washer will stop mid-cycle and start draining to prevent water from flowing out of the drum. In other cases, you might have to manually turn off the water supply and the washer to troubleshoot the error.

What other issues can occur as a result of the washer overflow?

An overflow in a washing machine can lead to a range of issues, such as a build-up of mold, mildew, and bacteria in the appliance. It can also create unpleasant smells, which may transfer to your laundry during cycles.

Unfortunately, when a washer overflows, it affects not just the appliance itself but also everything around it. Depending on the severity of the issue, you might notice damage to the floors, walls, and other appliances.

Can I prevent water damage caused by a washer overflow?


Proactive maintenance and preventive care can help you minimize the potential damage of an overflowing washing machine.

For starters, make the shut-off valve easily accessible. Being able to turn off the water supply as soon as water leaks out of your washer can help you avoid significant damage to your floors and your appliance.
