Samsung dishwasher code table

Scan by code, meaning, and severity, then open the exact detail page when you need step-by-step guidance.

1E
On WaterWall models, 1E indicates the filter is clogged and restricting water flow. On rotary spray arm models, 1E indicates the water temperature has risen above safe operating limits or the high-temperature heater is faulting.
medium severity
3C
The dishwasher's wash pump has failed or is not operating within normal parameters. The pump is responsible for circulating water through the spray arms during the wash cycle. When 3C appears, the pump cannot move water and the wash cycle stops.
high severity
3E
The incoming water supply to the dishwasher exceeds the safe operating temperature limit (above 176°F / 80°C). Samsung dishwashers heat their own water and are designed for a cold or warm supply — not a supply that is already at high temperature.
medium severity
4C
Samsung dishwasher error 4C usually means the machine is not getting enough incoming water to fill correctly.
medium severity
5C
Samsung dishwasher error 5C usually means the machine cannot drain water from the tub at the end of the cycle.
medium severity
7E
The WaterWall reflector arm that sweeps back and forth to distribute water across the lower rack cannot complete its full range of motion. This error applies exclusively to Samsung WaterWall dishwasher models — standard rotary spray arm models do not display 7E.
medium severity
9E
The dishwasher has detected that the water level inside the tub is lower than required for safe operation. The water level sensor cannot confirm that enough water is present for the cycle to run without risk of pump damage or heating element damage.
medium severity
AP
The dishwasher is in Wi-Fi Access Point mode, ready to be connected to the Samsung SmartThings app. AP is a mode indicator, not a fault. The dishwasher is broadcasting its own temporary Wi-Fi network so a phone can connect directly during setup.
low severity
bE
The dishwasher's control panel has detected that one or more buttons are continuously pressed. A stuck button prevents the control panel from accepting new inputs, which halts normal operation.
medium severity
CE
The dishwasher's internal electronic components cannot communicate with each other. A communication breakdown has occurred between the main control board and the display or motor control subsystem, halting the cycle.
high severity
HC
The dishwasher has detected that the water temperature is too high for the current cycle on rotary spray arm models. The heating element or water supply is delivering water above safe operating limits, and the cycle has been interrupted to prevent damage.
medium severity
HE
Samsung dishwasher error HE usually means the machine is not heating the wash water correctly.
medium severity
LC
Samsung dishwasher error LC usually means the leak sensor has detected moisture in the base area.
medium severity
OC
The dishwasher has detected that the water level inside the tub is higher than expected. The water level sensor has measured an overfill condition, and the cycle has been stopped to prevent overflow and potential water damage.
medium severity
PC
The Zone Wash function — which allows targeted intensive washing of one zone of the dishwasher — has detected a malfunction. The Zone Wash valve or the spray system for the selected zone is not operating correctly.
medium severity
PE
The Half Load function — which restricts washing to only the upper or lower rack to save water and energy on smaller loads — is not operating correctly. The valve or spray system controlling the inactive rack zone is malfunctioning.
medium severity
tE
The dishwasher's temperature sensor (thermistor) is returning readings that are outside the expected range for normal operation. The dishwasher cannot accurately control the water heating cycle and has stopped to prevent operating at an unknown temperature.
high severity

Common symptom shortcuts

These clusters give users another way into the list when they know the symptom but not the code.

Drain and standing water problems

  • 1E - On WaterWall models, 1E indicates the filter is clogged and restricting water flow. On rotary spray arm models, 1E indicates the water temperature has risen above safe operating limits or the high-temperature heater is faulting.
  • 5C - Samsung dishwasher error 5C usually means the machine cannot drain water from the tub at the end of the cycle.
  • LC - Samsung dishwasher error LC usually means the leak sensor has detected moisture in the base area.

Leaks, fill, and water-path issues

  • 1E - On WaterWall models, 1E indicates the filter is clogged and restricting water flow. On rotary spray arm models, 1E indicates the water temperature has risen above safe operating limits or the high-temperature heater is faulting.
  • 3C - The dishwasher's wash pump has failed or is not operating within normal parameters. The pump is responsible for circulating water through the spray arms during the wash cycle. When 3C appears, the pump cannot move water and the wash cycle stops.
  • 3E - The incoming water supply to the dishwasher exceeds the safe operating temperature limit (above 176°F / 80°C). Samsung dishwashers heat their own water and are designed for a cold or warm supply — not a supply that is already at high temperature.

Door, latch, and lock warnings

  • LC - Samsung dishwasher error LC usually means the leak sensor has detected moisture in the base area.
