Samsung Washer Error Codes — Causes & Fix

Samsung washers report faults as letter-number codes that name the failed system directly, which beats the blink patterns other brands use. Group the code by its family — water, drain, balance, motor, or door lock — and you know where to look. The one trap to know first: on a 7-segment display the digit "5" looks like an "S," so the drain code "5E" is often misread as "SE."

Read the Stored Codes#

On WF front-load models, hold Temp and Spin Level together for 5 seconds to show recent codes; on WA top-load models, hold Delay End and Soil Level for 5 seconds. On a Wi-Fi model, SmartThings Smart Care reads the stored log by NFC or audio tone and describes it in plain language.

Water and Drain — nF, 4E, 5E, OE#

An nF or 4E means no water filled in time. Samsung's inlet-valve orifices are narrower than Whirlpool's or LG's, so [Sacramento](/sacramento/sacramento)'s hard water (150-300 ppm) scales them faster — pull the hoses and check the inlet screens for white mineral buildup, meter the solenoid for 900-1200 ohms, and confirm both supply valves are open and pressure is at least 20 PSI. A 4E2 means the incoming water is too hot (above 70C), so set your heater to about 120F. A 5E (the one that looks like SE) means it did not drain in time — cleaning the debris filter behind the lower-left door resolves about 35% of these on the spot, then check the pump impeller and the 24-36 inch drain-hose height. An OE is overflow: the machine drains non-stop as a safety measure, usually from an inlet valve that will not fully close.

Balance and Door — UE/Ur and dC/dE#

UE or Ur is an unbalanced load — redistribute a heavy single item first. But if UE keeps returning with well-distributed loads on a VRT Plus front-loader, the three steel balls in the balance ring have flat-spotted and the ring is replaced; worn shock absorbers (DC66-00470A) or top-load suspension rods do the same. dC or U6 means the door-lock signal dropped mid-cycle, often when vibration works the lock connector loose. dE or dE1 means the lock never confirmed engagement: no click means an electrical fault (a burned-out wax motor or wiring), while a click with no latch means the lock (DC64-01538A) jammed mechanically.

Motor — the 3E Family#

Samsung's direct-drive motor uses a hall sensor to report rotor speed, and the 3E family means the board cannot verify the motor. Plain 3E is no feedback from the hall sensor, 3E1 is an overload (an overloaded drum or a seized bearing), and 3E3 or 3E4 point at shorted motor windings. The good news: 3E codes are most often the hall sensor — a small three-wire board on the stator that takes about 20 minutes to swap — not the motor itself, so try the sensor first. 8E is an overcurrent, often a locked transmission on a top-loader.

After the Repair, Clear the Code#

Unplug the washer for 60 seconds, then run a short Rinse and Spin. If the code returns, the underlying fault is not fixed — the board re-detects it and re-displays it, so resetting alone never solves anything. One recurring theme worth acting on: Samsung control boards are notably surge-sensitive, and a surge can cause 5E (dead pump relay), AE (a board-to-board communication fault), or 3E and 8E, so a surge protector is cheap insurance.
