Dishwasher codes can concern water entering, leaving, or being detected where it should not be. Similar labels can mean different things across makers, so match the manufacturer and model before using any instructions. The article scope may not cover every Samsung dishwasher model or revision.
0COver-level water error: more water is detected in the dishwasher than expected.
If water is visible outside the appliance, stop and contact Samsung. Do not treat the code as proof that a reset is safe.
1ECode meaning depends on dishwasher type: Samsung lists a WaterWall filter issue on WaterWall models and a high-temperature-heater error on rotary models.
This is intentionally model-scoped; identify whether the dishwasher uses a WaterWall or rotary wash system before interpreting the code.
3CPump-operation error.
The display does not make an owner-level pump diagnosis. Use Samsung's support path if the error remains.
3EHigh-temperature water-supply error.
Samsung assigns this meaning to its dishwasher line; do not reuse a washer interpretation for the same characters.
4CWater-supply pressure or temperature is outside the dishwasher's expected range.
Use the dishwasher's own manual; a matching washer code has a different appliance context.
4EWater-supply pressure or temperature is outside the dishwasher's expected range.
Use the dishwasher's own manual; a matching washer code has a different appliance context.
5CDrain error: Samsung says the dishwasher cannot drain.
Drain arrangements and owner-accessible filters vary by model. Do not pull out a built-in dishwasher for a general code check.
5EDrain error: Samsung says the dishwasher cannot drain.
Drain arrangements and owner-accessible filters vary by model. Do not pull out a built-in dishwasher for a general code check.
6EThe control panel detects a stuck button.
The exact control layout varies; stop if a key or panel appears physically damaged.
7EWaterWall reflector error; the reflector is not moving as expected.
This meaning applies to WaterWall models; other Samsung dishwasher designs may not use that component.
9ELow-water-level error: Samsung says there is not enough water in the dishwasher.
Use the model-specific manual if this repeats. A code does not identify whether supply or an internal component is responsible.
bEThe control panel detects a stuck button.
The exact control layout varies; stop if a key or panel appears physically damaged.
CECommunication error: the control panel cannot communicate with the rest of the dishwasher.
If the code returns, use Samsung service rather than opening the control panel.
HCHigh-temperature heater error; Samsung says the dishwasher temperature is too high.
This is a dishwasher-specific meaning and should not be inferred from a washer or dryer HC code.
HEHeater error: the dishwasher temperature is being detected incorrectly.
This code is not a stand-alone heater diagnosis; use the exact model support path if it recurs.
IECode meaning depends on dishwasher type: Samsung lists a WaterWall filter issue on WaterWall models and a high-temperature-heater error on rotary models.
This is intentionally model-scoped; identify whether the dishwasher uses a WaterWall or rotary wash system before interpreting the code.
LCLeakage error: Samsung says the dishwasher leak sensor detected moisture. WaterWall models may also report a blocked reflector.
This is a stop-and-support code. Do not run another cycle or pull a built-in unit to look for hidden water.

Before you act
Dishwashers: A leak or water-protection warning can involve hidden water near electrical parts. Do not pull the unit from cabinetry, remove panels, or run another cycle to locate a leak.
