Simply Swider’s Expert Guide For Fixing The Samsung Washer Code U6

Listen up:

You’ve got a mountain of laundry and zero time to waste. You fire up your Samsung washer, and boom—there it is: the dreaded U6 error code. Believe me, I get it; it’s frustrating.

First-hand Experience:

Not only have I tackled this U6 demon in the trenches, but I’ve also been the go-to guy for folks stuck in this exact jam. Trust me, it’s fixable.

The Expert Take:

To make sure you’re getting the most reliable info, I teamed up with Gary Smith, a home appliance specialist out of Ohio. We’re pooling our expertise to get you out of this mess.

So, are you ready to kick that Samsung Washer Code U6 to the curb? Let’s dive in.

Samsung Washer Code U6

What Is Samsung Washer Code U6?

The Samsung washer code U6, or the UB error code, indicates an instability in the washer’s motion. This code is typically caused by improper or unbalanced load. Worn components like the drive belt, shock absorbers, suspension springs, and rods also cause it. Additionally, a malfunctioning control board can also trigger the U6 error.


If your washer has a control glitch, all it needs is a reset. So just unplug your washer, wait for at least five minutes, then plug it back in and turn it on.

Still not fixed?

Let’s discuss the common reasons for the Samsung washer code U6 and how to troubleshoot each scenario.

1. Unbalanced Load

Listen up, folks:

Whether you’ve got a handful of clothes or a heap that rivals Mount Everest, the urge to stuff it all into your Samsung washer is real.

But let me tell you:

From years of fixing washers—doing so is a bad idea. Your Samsung washer has a weight limit for a reason: crossing it is a one-way ticket to the dreaded U6 error.

But wait, there’s more:

Loading too little into the drum is just as problematic. The drum can’t maintain its balance, and voila—you’re stuck with that pesky U6 error again.


Here’s how to spot the issue:

For overloaded machines, clothes will likely form a tangled ball in the drum, and you might hear some pretty unsettling noises.

As for underloading, the machine struggles to complete a spin cycle, making your laundry day twice as long and half as effective.


So, what’s the fix?

Your washer’s manual will tell you its maximum capacity. Stick to that. And if you think of throwing in that heavy towel with your t-shirts, don’t.

Gary, a seasoned technician, chimes in: “Absolutely avoid small items like shoelaces or stringy fabrics.”

He’s right.

Tiny items can create tangles and mess with the drum’s balance. The end game? Your screen flashes the U6 error, and you’re calling me to fix it.

So save us both the trouble and balance your loads, will you?

2. Washer Isn’t Level

Your Samsung washer acting like a seesaw isn’t just annoying—it’s a red flag. An unlevel washer can mess up your laundry and trigger error codes like the dreaded U6.

Let’s break it down.


“Jason, how do you spot a wobbly washer?” I get this question a lot. And I always say: “If one leg’s shorter, the machine tips forward or back.”

Trust me, I’ve seen enough of these cases to agree wholeheartedly.

Here’s the deal:

Don’t trust your eyes alone; use a bubble level. Place it on the washer’s top. If the bubble stays within the lines, you’re good. If it strays, note which way it leans. This tells you which leg needs a tweak.


Fixing a leaning tower of a washer is no big deal. Here’s your game plan:

  • Step 1: Unplug and power off. Safety first, folks.
  • Step 2: Prop up the washer. A wooden block works great here.
  • Step 3: Time to tweak that leg. Adjust until the machine stands firm when you nudge it.

But wait, what if the leg’s busted? No stress. Replacing a Samsung washer leg is a cakewalk.

Follow these steps:

  • Step 1: Unplug, power off.
  • Step 2: Lift and prop, just like before.
  • Step 3: Unscrew the gimpy leg. Screw in the new one. Make sure it sits flush with the base.
  • Step 4: Adjust until level. Trust your bubble level; it won’t lie.

There you have it. Your washer’s no longer a dancing queen, and you’re spared from annoying error codes.

3. Worn Drive Belt System

I’ve had a long day in the trenches fixing washers, and one case really caught my attention.

A stressed-out client called me over, baffled by a Samsung washer displaying the dreaded U6 error code. She thought she’d overloaded the machine.

But here’s the twist:


After a quick look, I pinpointed the real culprit—a worn-out drive belt system.

You see, this system turns the drum. Over time, it’s bound to show signs of wear and tear. We’re talking about a rubber belt and wheels that spin the drum. When this goes haywire, you’re looking at a U6 error.


Gary, another seasoned tech, always says, “A burning rubber smell is the first giveaway.” He’s right, but sometimes the smell is subtle or non-existent.

So, here’s how you confirm it:

  • Step 1: Unplug the washer. Shut off the water.
  • Step 2: Unscrew and remove the back panel.
  • Step 3: Check out the drive belt at the back. Look for fraying, scorch marks, or any other damage.


Find damage? Time for a new belt.

Good news—you can replace it yourself:

  • Step 1: Power off and turn off the water supply.
  • Step 2: Unscrew the back panel, then take it off.
  • Step 3: Pull out the damaged belt.
  • Step 4: Slide in the new one, making sure it fits snugly around the pulleys and drum. You might need to give the pulley a little spin to get the belt just right.
  • Step 5: Put the back panel back, screw it in.
  • Step 6: Plug it in and fire it up.

There you have it, a hands-on guide to fixing the U6 error stemming from a worn drive belt system. Trust me, it’s a lot less complicated than it sounds.

4. Defective Shock Absorbers

Let’s face it, nobody likes a washing machine that dances around during the spin cycle. I’ve seen it countless times, including once with a Samsung WA45T3200AW like this Reddit user. The drum was all over the place.


First off, always remember to turn off both the water and electricity before you lay a finger on that washer. Trust me, it’s for your own good.

If you’re experiencing drum movement issues, there’s a good chance the shock absorbers are worn or detached, or maybe even the connecting brackets have given up.


Ready to get your hands dirty? Let’s replace those faulty shock absorbers.

  • Step 1: Safety first. Disconnect the machine from both water and electricity.
  • Step 2: Unscrew the bottom front panel screws. You might need a support to prop up the washer.
  • Step 3: Next, remove the screws on the top panel and lift it off.
  • Step 4: Pop off the control panel and disconnect the wiring.
  • Step 5: Open the door, undo the screws for the door switch assembly, and remove the door seal.
  • Step 6: Close the door. Unscrew and remove the front panel to get to the front shock absorbers.
  • Step 7: Take off the back panel for access to the rear shock absorbers.
  • Step 8: Replace the old shock absorbers under the drum. Double-check those brackets. Tighten or replace as needed.
  • Step 9: Time to put the back and front panels back.
  • Step 10: Tighten the screws for the door switch assembly and slide that door seal back on.
  • Step 11: Reconnect the control panel and its wiring.
  • Step 12: Slide in the detergent drawer and put the top panel back.
  • Step 13: Screw in the bottom screws, and reconnect your machine to the water and electricity.

There you have it. Your washing machine should be back to its old, stable self. No more laundry room gymnastics.

5. Damaged Suspension Springs

Here’s the deal:

The suspension springs are what link your washing machine’s drum to its main framework. These metal springs keep the drum suspended during wash cycles.


I’ve seen it firsthand—these springs can wear out, stretch, or even snap. When that happens, your drum’s rotation gets all wonky, leading to the dreaded U6 error.


How do you know you’ve got a suspension spring issue?

First, your washer starts doing a shaky dance while running. The tub’s movement goes from smooth to erratic, and the machine vibrates. Then, there’s a dead giveaway: your washer stops spinning and makes a banging noise. Trust me, you can’t ignore it.

Time to get hands-on. Check the springs. You’ll find them at the back of your washer. Look for any signs of stretching or breakage.


Gary once told me, “You can’t repair a damaged Samsung washer suspension spring.” He’s absolutely right.

So, what’s the fix? Simple. Replace the springs.

Good news:

Gary and I have a step-by-step for you:

  • Step 1: Turn off the machine. Disconnect the power and water supply.
  • Step 2: Remove the top panel screws and lift the panel off.
  • Step 3: Detach the back panel and prop something under the drum—keeps it from tumbling when you mess with the springs.
  • Step 4: Locate the faulty springs. Get them out. A sturdy rope helps lift the spring off.
  • Step 5: Install new springs. Make sure to hook the bottom before the top.
  • Step 6: Remove your drum support, and put the back panel back on. Secure it with screws.
  • Step 7: Replace the top panel and turn the water back on.
  • Step 8: Power up your washer.

A quick tip: If one spring’s gone wrong, change them all. It keeps the drum balanced and lowers the odds of facing that U6 error again.

And there you have it.

6. Broken Suspension Rods

We’ve all been there. You load up your washing machine, press start, and suddenly you’re met with an unfamiliar error code – the dreaded U6.

This is often a sign that the machine’s drum isn’t stable, and in many Samsung top loaders, the culprits are the suspension rods. These rods are paramount for keeping the drum steady, ensuring your wash cycle runs smoothly.


So, how can you be sure it’s the suspension rods? Well, based on years on the field, I can tell you this: The washer’s movement gives it away.

Samsung Broken Suspension Rods

If your machine shakes or vibrates excessively during the wash cycle, you might be dealing with faulty suspension rods.

Personally, I often push down on the tub to test its bounce. If it’s too springy, that’s another red flag. But to be certain, you’ll want to open her up. Lift the top panel, locate the rods, and check if they’re bent or damaged.


Just a few weeks ago, I received a call about this same U6 error on a Samsung washer model WA40J3000AW/AA. On arrival, it was shaking like it was in a rock concert! After a quick chat with my buddy Gary, who’s seen this more times than I can count, we pinpointed the suspension rods as the troublemakers.

If you’re facing a similar dilemma, here’s the game plan we followed to set things right:

  • Step 1: Safety first! Turn off both the power and water supply to your washer.
  • Step 2: Remove the top panel by unscrewing its fasteners. Remember, you might have some access panels to deal with first.
  • Step 3: Prop up the panel securely. You’ll need both hands for the next steps.
  • Step 4: The suspension rods are in each corner of the machine. Find the one that’s acting up.
  • Step 5: Gently remove the faulty rod and slot in its shiny new replacement.
  • Step 6: Once done, lower the top panel and secure it back with the screws.
  • Step 7: Power up, turn on the water, and you should be back in business.

In the end, while these fixes might sound daunting, with a little patience and know-how, you’ll have your machine running smoothly in no time.

And if ever in doubt, don’t hesitate to call a pro!

7. Control Board Communication Issue

During my years as an appliance technician, I’ve often called the control board the “brain” of the washing machine.


Because it orchestrates every function within the machine. When the control board can’t properly communicate with other components, it can result in the notorious U6 error.

What’s tricky is that this board is connected to the control panel. So, sometimes, even if there’s no actual issue with your washer, a miscommunication can still display an error.


Let me share a quick tip: A malfunctioning Samsung washer main control board often reveals signs of burn or damage.

From my experience:

I suggest looking out for any dark spots or fractured parts on the board. Those are your telltale signs.


Here’s a quick fix I’ve relied on countless times: Simply reset the washer. Turn it off, wait a few minutes, and switch it back on.

Sounds too simple? You’d be surprised how often that works.

But if things are a bit more severe and you spot damage on the control board? Well, it’s time for a replacement. Here’s how I do it:

  • Step 1: Disconnect power and water from the washer.
  • Step 2: Unscrew and remove the back panel.
  • Step 3: Take out the screws holding the control panel; lift it.
  • Step 4: Open the tabs locking the control board housing.
  • Step 5: Before anything else, snap a quick photo of the control board’s connections. (This saved me multiple times from making wrong connections.)
  • Step 6: Disconnect the wires and unscrew the control board.
  • Step 7: Replace the faulty board with the new one.
  • Step 8: Using your earlier photo as a guide, reconnect the wires.
  • Step 9: Secure the control board, ensuring the housing tabs lock.
  • Step 10: Reattach the control panel and the back panel.
  • Step 11: Reconnect the washer to power and water. Test it out!

Remember Gary’s advice?

He always says, “Capture the control board connections before touching anything.” He’s right. Trust me, that picture is a lifesaver when you’re trying to get things back in order.
