Codes / Samsung / washer

Samsung washer error codes

14 codes, 34 owner checks, every one restated from a Samsung support page for the United States and linked below with the date it was read. Nothing here comes from a forum, a repair blog or a service manual, and this site adds no step Samsung does not list.

Samsung publishes its own list of these codes, and it is the first thing worth reading: Samsung washing machine information and error codes. What the pages below add is one screen per code: the checks in Samsung's order, drawn as a decision tree with its exits marked, and a plain statement of where Samsung's own page stops.

Every verified Samsung washer code

If your display shows something else

Samsung shows the same fault under different strings on different models. Every variant recorded on these pages is below, with the code page that carries it. This site does not split a fault into one page per variant.

How far Samsung's own pages go

This matters more than the code itself, and it is the one thing a code list usually leaves out. For some of these codes Samsung's page is a complete answer; for others it stops well before the problem does. Two separate things are worth knowing before you click: whether Samsung names a service route at the end, and how many owner checks it gives you before that.

8 of these 14 codes end at a service route Samsung names itself. Where that happens, the red box at the foot of the decision tree is Samsung's own instruction, restated, not a judgement made here.

The 6 where Samsung names no service step

For these, Samsung's page gives no instruction for what to do when the checks fail — in several cases because it treats the code as a setting or a normal mode rather than a fault. Those pages say so, and the stop point on them is this site's editorial boundary, labelled as such on the page, not Samsung's.

• 4C2The cold supply water is extremely hot, usually swapped hoses.
• CbNot a fault: calibration mode is running.
• CLChild Lock drained the tub and is showing the code.
• SDCThe detergent drawer is not fully closed.
• SUDToo many suds: the washer pauses, then continues on its own.
• UbThe load is unbalanced in the tub.

The 4 with a single owner check

Samsung lists exactly one owner check for these. If that check does not settle it, its page has nothing further for an owner, and neither does this site. What a service call would be dealing with instead is named after each one.

• 4C2The cold supply water is extremely hot, usually swapped hoses. The inlet thermistor and the valve assembly. Samsung's page stops at the hose connections.
• 9C1The electrical supply to the washer is irregular. The washer's power board. The house circuit itself is an electrician's work. This site describes no electrical work at all.
• dnThe washer is installing a software update. The control board and the washer's network hardware.
• SDCThe detergent drawer is not fully closed. The drawer switch and the dispenser assembly. Samsung's page stops at closing the drawer.

If your code is not on this page

It means no Samsung page for it had been read when this list was built, not that the code is unimportant. The code lookup will say so plainly and point you at the Samsung pages this site has read, and the methodology page lists what was deliberately left out and why. Whatever the code, when to stop and call a technician applies.

Pages read for this list

A list page exists here only for a brand and appliance with at least 6 verified codes. Not yet reviewed by an appliance technician. Model-specific pages are not built until that review happens (see /methodology/). Model-specific pages are not built: see sources and review.
