What we can confirm
Code SUd, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
SUd
Not a malfunction. The washer has detected more foam than it can work with, has paused to let it settle, and will carry on by itself. Samsung says plainly that this does not need service, and the cause is detergent: too much of it, or a detergent that is not HE. The reason it is worth understanding rather than ignoring is that foam also produces other codes — a drum full of suds can report a filling or a drain problem that disappears the moment the foam does — so a machine that has been over-dosed for months can look like several different repairs.

What it narrows down to
Too much foam, and the machine is waiting for it to collapse
Diagnostic

On the same appliance
What else belongs to the washers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
Water where it should not be, or a level sensor that cannot agree with itself
Water is not arriving at the rate the machine expects
The cold inlet is being fed hot water
The water is not leaving, or not leaving fast enough
More water in the drum than the cycle called for
The panel thinks a button is being held down
The supply is not what the machine expects
The door is not being seen as shut and locked
The dispenser drawer is not fully closed
The small add-laundry door is not latched
The drum cannot be spun safely with the load as it sits
The machine is recalibrating its weight sensing, which is normal

About Samsung washer error code SUd
What SUd means on this make
Not a malfunction. The washer has detected more foam than it can work with, has paused to let it settle, and will carry on by itself. Samsung says plainly that this does not need service, and the cause is detergent: too much of it, or a detergent that is not HE.

The other ways Samsung prints this one
SUd · 5UD · Sd · 5d · SUdS · 5Ud5
Samsung publishes a condition and then every string that can stand for it, and which one your machine shows depends on the panel it was built with. They mean the same thing and they are one page here, so whichever of them you searched for, this is the right page.
Where this appears, and why not to clear it
On the appliance's own display. Samsung reports errors two ways: machines with a digital display show a code, and the same machines without one blink their cycle lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power — Samsung asks for this itself on its refrigerator and dishwasher pages, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.
What to do about it
- Let the cycle finish. It usually will.
- Cut the detergent dose. On a modern high-efficiency machine the right amount looks wrong to anyone who learned on an older one.
- Check the detergent is marked HE. Ordinary detergent in an HE machine produces exactly this.
- Run one or two empty cycles with nothing added to clear what is left in the system.
Where this goes next
The job this usually becomes is diagnostic visit, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 506-1256 and describe what the panel is doing before booking anything.
