All Samsung dishwasher error codes with step-by-step troubleshooting, multimeter specs, and OEM part numbers.

36 error codes

CodeMeaning
3CThe control board lost communication with the wash motor controller. The motor did not respond to commands from the main board.
highadvanced
4CThe dishwasher started a fill cycle but did not detect sufficient water flow within the expected time window.
moderatebeginner
5CDrain 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.
moderatebeginner
9EThe water level sensor circuit reported an out-of-range value. The control board cannot confirm correct water level during the fill cycle.

BEEPINGSamsung 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.

DIAG-MODESamsung 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.

DRAIN-ISSUESWater 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.

LIGHTS-FLASHIndicator 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.

NO-WATERWhen 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.

NOT-WASHINGA 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.

OCThe water level inside the tub has risen above the safe maximum. The float switch or overflow sensor triggered a shutdown.
criticalintermediate
OEWater level reached the overflow threshold. The overflow float or level sensor triggered an emergency shutdown.

PCThe pressure switch or water level pressure sensor circuit is reporting an abnormal reading. The control board cannot determine water level accurately.

SCThe dishwasher failed to drain within the expected time. The drain pump did not clear water from the tub.

SEDrain cycle failed. SE is the older firmware equivalent of SC and 5C - all three codes indicate the same drain pump or blockage fault.

SMELLSA Samsung dishwasher smells bad has specific causes related to Samsung's design and component choices.

SOAP-DISPENSERThe 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.
mediumbeginner
STOPS-1MINA 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.

TURNS-ON-ITSELFA 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.
