Short answerSamsung often shows one fault in several spellings: older models use an "E" suffix and newer ones a "C" (4E → 4C, 5E → 5C), and the display can turn S into 5 or O into 0. Look up your code in any of its forms below. Many codes clear after a power cycle; if one comes back, the table shows the part to check.
Notice: Samsung warns that a reset clears the
stored code but not the fault. On refrigerators, don't reset
before a technician visit — it erases the error history.
How to reset
- Washer / dryer: unplug or switch off the breaker for 1–5 minutes, then power on.
- Dishwasher: troubleshoot first, then breaker off for 30 seconds to 2 minutes.
- Refrigerator: unplug about 5 minutes — Samsung rarely recommends it.
- Washer calibration (fixes Ub/UE, weak spin): empty the tub, hold Temp + Delay End 3 s until Cb shows, press Start. Turn off when End shows.

Find your model number
Ranges: open the oven door and check the top-left of the frame, or the left side of the bottom drawer frame. Washers and dryers: around the door opening or on the back (front-load); on the back (top-load). → Model Number Locator.
FAQ
What does 5C mean on a Samsung washer?
It can't drain. Clean the pump filter and check the drain hose.
Why does my Samsung fridge say OF OF?
It's in Cooling Off (demo) mode — nothing cools. Exit the mode; no
service is needed.
What does dC mean on a Samsung washer?
The door isn't detected as closed and locked.
How do I fix 22E on a Samsung fridge?
The fridge fan is usually iced. Unplug, leave the doors open for
several hours, then plug back in.
Will resetting clear the error?
It clears the code but not the cause. Troubleshoot first.
