Dishwasher

Code	Meaning	Severity
3C	The control board lost communication with the wash motor controller. The motor did not respond to commands from the main board. high	high
4C	The dishwasher started a fill cycle but did not detect sufficient water flow within the expected time window. moderate	moderate
5C	Drain cycle failed. The dishwasher could not clear water from the tub within the timeout period. 5C is the older display variant of the SC drain fault. moderate	moderate
9E	The water level sensor circuit reported an out-of-range value. The control board cannot confirm correct water level during the fill cycle. moderate	moderate
BEEPING	Samsung dishwashers beep to communicate cycle status, error conditions, and door alerts. Unlike older dishwashers with single-tone buzzers, Samsung models use a specific number of beeps combined with a display code to signal different fault conditions. The beep count and pattern on Samsung DW80R and DW80K series is part of the fault communication system. medium	medium
DIAG-MODE	Samsung dishwasher diagnostic mode is a built-in service test that cycles through each major component - water fill, wash pump, drain pump, heater, and dispenser - in sequence to isolate which system is causing a fault. On Samsung DW80R series and most post-2016 Samsung dishwashers, diagnostic mode is accessed by holding the Start button for 5 seconds with the door closed. low	low
DRAIN-ISSUES	Water remains in the tub after the cycle completes, or the dishwasher drains slowly. May or may not be accompanied by a SC, 5C, or SE error code. moderate	moderate
ERROR-CODES	Complete reference table of every Samsung dishwasher error code with brief meanings and repair priorities. moderate	moderate
HOW-TO-START	Step-by-step guide to starting a Samsung dishwasher correctly, including delay start, child lock check, and troubleshooting when the machine does not begin a cycle. low	low

LC	Water or moisture detected in the base pan beneath the dishwasher tub. The leak sensor DD81-01399A has been activated. critical	critical
LE	The wash motor has locked up, stalled, or lost communication. The control board detected the motor did not reach operating speed. high	high
LEAKING	A Samsung dishwasher leaking has specific causes related to Samsung's design and component choices. medium	medium
LIGHTS-FLASH	Indicator lights on the control panel are flashing. The pattern and which lights flash indicate whether this is an error state, a pause state, or a control board reset condition. moderate	moderate
NO-WATER	When a Samsung dishwasher starts a cycle but no water enters the tub, the machine is receiving power and the control board is operating, but the water inlet valve is not opening. Samsung dishwashers display a 4C or 4E error code for water supply failures - 4C is the current code on DW80R series, while 4E was used on older Samsung models. Both codes mean the same thing: the flow sensor or tub level sensor did not register a fill within the expected time. high	high
NOISE	Causes and Fixes medium	medium
NOT-CLEANING	A Samsung dishwasher not cleaning dishes has specific causes related to Samsung's design and component choices. medium	medium
NOT-DRAINING	A Samsung dishwasher not draining has specific causes related to Samsung's design and component choices. medium	medium
NOT-DRYING	A Samsung dishwasher not drying dishes has specific causes related to Samsung's design and component choices. medium	medium
NOT-FILLING	4C Error and Inlet Valve Fix medium	medium
NOT-WASHING	A Samsung dishwasher that fills with water but does not wash has a circulation pump failure, a blocked WaterWall reflector arm (on Samsung WaterWall models), or a control board that is not activating the wash pump. Samsung DW80R series models use the WaterWall technology where a linear reflector moves back and forth instead of spinning spray arms - this reflector can jam on tall items or the drive mechanism can fail. high	high
OC	The water level inside the tub has risen above the safe maximum. The float switch or overflow sensor triggered a shutdown. critical	critical
OE	Water level reached the overflow threshold. The overflow float or level sensor triggered an emergency shutdown. critical	critical
PC	The pressure switch or water level pressure sensor circuit is reporting an abnormal reading. The control board cannot determine water level accurately. moderate	moderate
RESET	Soft reset, hard reset, and control board reset procedures for Samsung dishwashers. low	low
SC	The dishwasher failed to drain within the expected time. The drain pump did not clear water from the tub. moderate	moderate
SE	Drain cycle failed. SE is the older firmware equivalent of SC and 5C - all three codes indicate the same drain pump or blockage fault. moderate	moderate
SMELLS	A Samsung dishwasher smells bad has specific causes related to Samsung's design and component choices. medium	medium
SOAP-DISPENSER	The detergent dispenser on Samsung dishwashers uses a bi-metal strip or wax motor actuator to spring open the dispenser door at a specific point in the wash cycle. When the dispenser fails to open, dishes come out dirty and coated in undissolved detergent residue. Samsung dispensers on the DW80R and DW80K series use a solenoid-actuated spring latch - unlike some brands that use heat alone to trip the dispenser. medium	medium
STOPS-1MIN	A Samsung dishwasher that stops within the first 1-2 minutes of starting a cycle has failed a startup safety check. Samsung dishwashers run a series of pre-cycle checks immediately after start: door latch verification, anti-flood sensor check, and initial water fill confirmation. If any of these checks fail within the first 90 seconds, the control board stops the cycle immediately to prevent unsafe operation. high	high
TROUBLESHOOT	Comprehensive troubleshooting guide covering the most common Samsung dishwasher problems, symptoms, and repair paths. moderate	moderate
TURNS-ON-ITSELF	A Samsung dishwasher that powers on or starts a cycle without user input has a control board relay stuck in the closed position, a touchpad membrane sending phantom key presses, or a Delay Start cycle that was inadvertently activated. On Samsung DW80R models with smart home connectivity, a scheduled cycle or app-triggered command from the SmartThings app is also a possible cause. medium	medium

Microwave

View all 3 codes →

Code	Meaning	Severity
C-10	C-10 on a Samsung microwave indicates a communication fault between the main control board and the smart/Wi-Fi module. This error only appears on Samsung Smart microwaves with SmartThings connectivity. low	low
HUB	Samsung microwave ovens display error codes including SE (stuck key), C-10 (communication fault on smart models), 5E (button stuck variant), and descriptive errors. Samsung microwaves use fewer codes than washers or dishwashers. medium	medium
SE	SE on a Samsung microwave means a key on the touchpad is stuck or shorted - the control board detects a key press that should not be happening. Samsung uses the generic SE code across multiple appliances (washers, microwaves) but on microwaves it specifically relates to the touchpad membrane. medium	medium

Oven

View all 10 codes →

Code	Meaning	Severity
C-21	Samsung oven C-21 means the NTC temperature probe resistance is outside the acceptable range - either reading too high (approaching open circuit) or too low (approaching short). The control board cannot establish a valid temperature reading and shuts the oven down as a safety measure. high	high
C-24	Samsung oven C-24 indicates a fault in the lower oven temperature sensor circuit on dual-oven models equipped with the FlexDuo divider system. C-24 is specific to Samsung FlexDuo ranges (NE59M6850SS, NE63T8911SS) - it appears only when the FlexDuo divider panel is installed, creating a separate lower oven cavity with its own dedicated NTC sensor. medium	medium
C-A2	Samsung oven C-A2 indicates the convection fan motor has failed or is not running at the required speed. On Samsung convection ranges, the fan circulates hot air inside the oven cavity for even baking. When the control board detects no fan rotation or insufficient fan speed, it displays C-A2 and may limit oven operation to prevent element overheating. medium	medium
C-F2	Samsung oven C-F2 means the oven temperature exceeded the 610 degrees F safety threshold, triggering an automatic shutdown. Unlike GE F2 which almost always points to a stuck relay on the control board, Samsung C-F2 has an additional possible cause specific to Samsung's design: a thermal cutoff fuse placed in series with the bake element circuit that blows at high temperatures and generates the same C-F2 code even when the board is working correctly. high	high
DOOR-STUCK	A Samsung oven door won't open after self-clean has specific causes related to Samsung's design and component choices. medium	medium
HUB	Samsung ovens display C-prefix error codes (C-21, C-F2, C-24, C-A2) that indicate sensor, temperature, and motor faults. All Samsung oven C-codes use an NTC thermistor for temperature sensing - a fundamentally different technology from the RTD probes used by GE and Frigidaire - making sensor identification the most critical step before ordering parts. high	high
NOT-HEATING	A Samsung oven not heating up has specific causes related to Samsung's design and component choices. medium	medium
SE	SE on a Samsung oven means a touchpad key is stuck or shorted, identical in concept to Samsung washer and microwave SE codes. The control board detects a continuous key press signal. medium	medium
SMOKING	Causes and Fixes medium	medium
WONT-START	A Samsung oven won't turn on has specific causes related to Samsung's design and component choices. medium	medium

Refrigerator

View all 19 codes →

Code	Meaning	Severity
22C	Samsung refrigerator 22C means the freezer evaporator temperature sensor has failed or is reading outside the expected range. The freezer evaporator sensor monitors the temperature of the evaporator coil assembly to manage the defrost cycle and compressor operation. A failed sensor causes the control board to lose freezer temperature data, potentially disrupting cooling cycles. high	high
25E	Samsung refrigerator 25E indicates the fridge compartment defrost sensor has failed or is reading outside the expected range. This is the refrigerator-side equivalent of 39C (which is the freezer defrost sensor) - 25E specifically monitors the defrost heater in the fresh food (fridge) section of French door and side-by-side models that have separate defrost circuits for each compartment. high	high
2E	Samsung refrigerator 2E means the freezer temperature sensor is shorted - its resistance has dropped to near zero ohms, which the control board interprets as an impossibly high temperature reading in the freezer. 2E is the shorted-sensor counterpart to 22C (open/drifted sensor) - both are freezer sensor faults but 2E specifically indicates a hard short rather than drift or open circuit. high	high
33E	Samsung refrigerator 33E indicates the ice room fan motor inside the ice maker compartment has failed or is not running. On Samsung French door models, a small dedicated fan circulates cold air through the ice maker compartment to keep ice from clumping. When this fan stops, the ice maker compartment temperature rises, ice sticks together, and eventually the compartment freezes completely solid, blocking ice dispensing. medium	medium
39C	Samsung refrigerator 39C means the freezer defrost sensor has tripped or failed, or the freezer defrost heater has failed causing ice to build up on the evaporator coils. The 39C code is the most frequently displayed Samsung fridge error because defrost heater failure is the single most common hardware fault in Samsung French door and side-by-side refrigerators. high	high
40C	Samsung refrigerator 40C indicates a fault in the ice maker room ambient temperature sensor - the sensor that measures the air temperature inside the ice maker compartment rather than the ice tray itself. This is distinct from 40E (which monitors the ice maker cycle sensor) and is specific to Samsung French door and 4-door Flex models that have a dedicated ice maker room with its own climate monitoring. medium	medium
40E	Samsung refrigerator 40E indicates a fault in the ice maker temperature sensor circuit. On French door and 4-door Flex models with automatic ice makers, the ice maker uses a dedicated temperature sensor to monitor the ice making tray and ice room temperatures. A failed or out-of-range sensor triggers 40E and interrupts ice maker operation. medium	medium
41	Error code 41 on a Samsung refrigerator indicates the ice room fan motor is not operating. This fan circulates cold air through the ice maker compartment. medium	medium
FREEZING	A Samsung refrigerator freezing food has specific causes related to Samsung's design and component choices. medium	medium
HUB	Samsung refrigerators display numeric and alphanumeric error codes on the door panel to indicate sensor, defrost, ice maker, and fan failures. The most common Samsung fridge codes - 39C, 33E, 22C, 25E, 2E, 40E, and 40C - all point to specific sensor or motor failures in the freezer, fridge, or ice maker circuits. high	high
