Samsung washer error codes: what each one means

This table covers Samsung washer information codes sold in the US, including common digital display codes and no-display light patterns. Use the meaning to identify the system involved, then start with the safe homeowner check. Stop and contact a technician when the first check says the fault is likely internal.

Reading the code

On digital models, codes appear on the control display; on no-display models, the washer may use blinking temperature or water level lights, such as Extra Large, Extra High, Large or High for a fill fault. To clear a code after fixing the cause, unplug the washer or switch off its breaker for 1 to 5 minutes, then restore power; do not keep clearing a code that returns. Cb or C6, CL, dn, Ur, refill detergent or softener messages, and the Self Clean LED are status messages rather than failed part faults.

Have the model number ready

The company will ask for it first. It's on a sticker or metal plate, usually in one of these spots:

Common questions about appliance repair

Can I reset a Samsung washer code?

Yes, but only after you address the likely cause. Unplug the washer or switch off its breaker for 1 to 5 minutes, then restore power; if the same code returns, stop clearing it so a technician can use the stored history.

Why does the same code keep coming back?

A recurring code means the control is still seeing the condition, such as poor fill, slow drain, a leak, an unbalanced load, or an internal sensor fault. Use the first check in the table, then involve a technician if the code returns.

Why do older and newer Samsung washer codes differ?

Many newer models use C codes like 4C, 5C, LC, OC and dC, while older displays may use E or two letter forms like 4E, 5E, LE, OE, dE, nd or nF. Some labels, especially dC, 3E, BE2 and 8E2, can mean different faults by model.

What if my washer only has blinking lights?

Treat blinking lights as a code only when the washer also stops or acts wrong. Match the light pattern to the fault group and use the same safe first check.

Still showing the problem after the checks?

Call and describe what you tried. You'll be connected with an independent repair company near you.
