Samsung washers use advanced sensor systems to monitor water levels, drum balance, motor load, door seal integrity, and temperature throughout each wash cycle. When any parameter falls outside expected ranges, the control board halts operation and displays a diagnostic error code. These codes are your washer's way of communicating exactly what went wrong and which component needs attention.
Washer error codes generally fall into these categories: water supply errors (low pressure, no fill, fill timeout), drainage errors (pump blocked, drain timeout, siphoning), motor and drum errors (overload, imbalance, lock-up), door/lid errors (switch failure, lock mechanism, seal leak detection), temperature errors (sensor open/shorted, heater failure, over-temperature), and communication errors (control board failure, wiring harness issues). Each category has distinct troubleshooting approaches detailed in our individual code guides.
Before diving into specific error code diagnosis, perform these universal checks that resolve approximately 25% of Samsung washer errors without further troubleshooting: verify both hot and cold water supply valves are fully open, check that the drain hose is not kinked or installed higher than 96 inches from floor level, ensure the washer is level (uneven washers trigger imbalance codes), confirm the load is not exceeding the rated capacity, and try a control board reset by unplugging the unit for 60 seconds. If the error persists after these checks, proceed to the specific code guide below.

Samsung washer dE error means the door lock system cannot confirm the door is closed. Most common cause: an obstruction in the door latch (40% of cases). Complete diagnosis guide with door lock replacement part numbers.
Samsung washer UE error means the drum detected an unbalanced load during the spin cycle. Most common cause: unevenly distributed laundry (60% of cases). Complete fix guide including calibration, leveling, and suspension rod diagnosis.
