How To Fix A Samsung SUD Or 5UD Error Code

Sometimes, your Samsung washing machine, especially the 5UD Samsung washer, might act up and show a SUD or 5UD error code.

But there’s no need to stress over it. This error usually means that your 5UD Samsung washer has noticed an excess of soap suds or too much foam during a washing cycle.

What Happens Next

When this error pops up, your 5UD Samsung washer takes a little break.

It adds more water and waits for those extra suds to disappear. So, it’s like your 5UD Samsung washer saying, “Hold on, we’ve got too many bubbles here.

What to Expect

Normally, the error goes away, and your 5UD Samsung washer gets back to work.

But sometimes, it doesn’t. The error code might stick around or come back later. That’s when you need to do something about it.

What Can You Do?

In our article, we’ll give you some tips on how to fix the problem with your 5UD Samsung washer and keep it from happening again.

We’ve got your back with practical solutions to get your 5UD Samsung washer running smoothly once more. So, no more worries about those soapy suds.

This guide is relevant to a wide range of Samsung models, encompassing the following:






















How to Avoid Suds Troubles in Your Washing Machine

1. Use the Right Amount of Detergent

One big reason for too many bubbles in your washing machine is using too much detergent.

It can happen in two ways: using too much soap in one wash or using too much soap regularly, which leaves a soapy residue in the machine.

To keep suds under control, follow the detergent guidelines for your load and avoid going overboard.

2. Go for High-Efficiency (HE) Detergent

HE detergents are made for washing machines that use less water, like high-efficiency washers.

If you use regular detergent in an HE washer, it can create an overload of suds, and that’s when the SUD or 5UD error might show up.

But the good news is you can use HE detergents in regular washers to cut down on suds. Usually, four tablespoons of HE detergent will do the trick for a regular washer.

3. Keep Your Washer Clean

Even though it sounds a bit odd, washing machines can get dirty over time. If detergent gunk builds up or the drain hose and pump get clogged, it can lead to way too many suds during a wash.

To fix this, use a washer cleaning product every six months. This will help keep your washer clean and clear any blockages in the drain hose or pump.

It’s an easy step that can save you from suds trouble and keep your washer working great.

How to Fix 5UD Samsung Washer or SUD Error Code in Your Washer

  1. Give It Some Time: First, let your washer have around 10 minutes to try and fix the issue on its own. It might sort things out.
  2. Tackle the Suds: If you still see too many suds, add about half a cap of fabric softener or half a cup of white vinegar into the detergent dispenser. This should help get rid of the extra suds.
  3. Try the ‘Eco Drum Clean’ Cycle: Some washers have a special cycle called “Eco drum clean.” Give that a shot. It can help clear out the suds.
  4. Unplug and Restart: If the error code doesn’t go away, unplug your washer from the power for 2 minutes. Then, plug it back in and turn it on. This might reset things.
  5. Are we still Seeing the Error? Follow These Steps: If the suds problem continues, don’t worry. We’ve got more tips to help you out.

How to Deal with a Stubborn SUD or 5UD Error Code in Your Washer

When that SUD or 5UD error code just won’t go away, even if you’re using the right amount of detergent, it’s time to dig into the issue.

Here’s how you can tackle the problem step by step:

1. Keep Your Washer Clean

Use a washer cleaning product or white vinegar to clear away detergent residue and remove any blockages that might be causing too many suds.

But remember, using vinegar too often can damage the rubber parts inside your washer.

It’s also a good idea to regularly clean the detergent dispenser and the area around it to prevent detergent buildup, which leads to excessive suds.

2. Check the Drain Pump and Filter

If your Samsung washer has an accessible drain pump and filter at the front, it’s relatively easy to clean them.

For models without this feature, you’ll need to unplug the washer and remove the front or rear panel (depending on the model) to access the drain pump.

Once you have access, clean the area to get rid of any debris that might be blocking the pump or filter.

3. Inspect the Drain Hose

A clogged drain hose can lead to detergent buildup and too many suds. If you’ve had drainage issues or error codes related to it, check the drain hose.

It’s usually simple to remove the external drain hose to check for blockages. For the internal drain hose, you may need to remove the front or back panel, depending on your model.

You can clean the drain hose using hot water, and if necessary, use a drain snake tool or white vinegar to clear it.

4. Look at the Foam Level Sensor and Water Level Sensor

Some Samsung washers have a foam level sensor, while others use a water level sensor. Both do the same job: they monitor foam and water levels.

If you’re seeing the SUD or 5UD error code when your washer isn’t in a wash cycle (like when it’s filling with water), these sensors might be the culprits.

You’ll usually find them behind the washer’s control panel. To access them, you’ll likely need to remove the top panel of your washer.

Once you locate the sensor, use a multimeter to test it for continuity. That means you need to check if there’s a continuous electrical path when you disconnect its wiring harness.

If the multimeter reading doesn’t change when you blow air into the hose connected to the sensor to simulate water pressure, it’s likely defective and should be replaced.

5. Main Control Board (Rarely Needed)

If you’ve tried everything and the error code just won’t budge, it might be an issue with the main control board.

However, this is quite rare. Diagnosing problems with the main control board can be complex, so it’s usually best left to a professional technician.

By following these steps, you can try to solve the persistent SUD or 5UD error code in your Samsung washer.

What Does 5ud Mean On A Samsung Washer?

When that SUD error pops up, the first thing you need to do is figure out why it’s happening.

There are a few common reasons:

  • Using a not-so-great laundry detergent.
  • Pouring in more detergent than your wash really needs.
  • Something’s off with the foam level sensor.
  • The pressure switch isn’t working like it should.
  • A clog in the release hose, branch pipe, or sewer.
  • In very rare cases, a big issue is with the control board.

Your first move should be to check the laundry detergent you’re using. Sometimes, that’s all it takes to fix the problem.

How Long Does a 5UD Samsung Washer Last?

Samsung washers are smart – they have a special feature to control excess suds.

But sometimes, if you see the SUD error, it means the washer can’t quickly get rid of the suds, and you’ll have to wait for the foam to go away on its own.

How long this takes depends on how much washing powder is in the water.

To prevent future occurrences, it’s crucial to use the correct detergent amount, opt for high-efficiency detergents, and regularly maintain your washer’s cleanliness.

In rare instances, professional assistance may be required if the issue remains unresolved.


Q: What exactly is 5E in a washing machine?

A: When your Samsung washer is in the middle of a drain cycle, and you see the 5E error code on the display, it signifies a drainage problem. This error indicates that there may be an obstruction or blockage preventing the proper drainage of water from the washer. In this context, 5E is the official error code associated with this issue.

Q: How do I fix Sud error on my Samsung washer?

A: Cleaning the Drain Pump Filter. In many Samsung washer models that exhibit the SUD error code, you’ll find a drain pump filter that can be accessed, removed, and cleaned. The SUD error often occurs when there’s an accumulation of suds and debris in both the drain pump filter and the cabinet around it.

Q: Why low-sud detergent?

A: More Suitable for Delicate Skin: If you have sensitive skin or specific conditions such as eczema or psoriasis, low-sud products are the way to go. These products require less detergent, which means your clothes have fewer remnants of soap. This reduction in leftover soap helps prevent potential skin irritation caused by lingering fragrances, enzymes, brightening agents, and dyes.

Q: Can I reset Samsung washing machine?

A: Resetting your washing machine can be a bit tricky, but you can achieve a similar effect by performing a power cycle. Here’s what you can do: Unplug the machine or switch off the power at the circuit breaker. Wait for a short period, typically 1 to 5 minutes, to ensure any residual electrical charge dissipates. Then, power it up again.
