On Samsung dishwashers, 4C/4E means not enough water pressure or temperature, 5C/5E means it isn't draining, LC/LE means the leak sensor detected moisture, OC/OE means the water level is too high, HE/HC/tE are heater and temperature faults, 3C is a pump problem and bE means a button is stuck. Cut power, check hoses, clean the filter and let the base dry; codes that return need a technician.
| Code | What it means | What you can do |
|---|---|---|
| 4C / 4E | Water pressure or temperature too low | Open the supply valve fully; check the hose for kinks. |
| 3E | Supply water too hot | Incoming water shouldn't exceed about 176°F. |
| 5C / 5E | Not draining | Clean the filter, check the drain hose and disposal connection. |
| OC / OE | Water level too high | Turn off; repeats mean a valve or level sensor fault. |
| LC / LE | Moisture in the base (leak sensor) | Cut power, check hose connections, don't overfill detergent, let it dry. |
| 9E | Water level too low | Empty the dishwasher and run a normal cycle; repeats need service. |
| 1E | Clogged filter (some models) or high temperature (other models) | Clean the filter and power-cycle. |
| Code | What it means | What you can do |
|---|---|---|
| HE / tE | Temperature sensing problem | Run a normal cycle; repeats need a technician. |
| HC | Too hot inside | Power-cycle at the breaker; repeats need service. |
| 3C | Pump malfunction | Turn off and retry; repeats need the pump. |
| bE / 6E | A button is stuck | Power off and press each button. |
| CE / PC / PE | Control communication or wash-feature fault | Power-cycle; repeats need diagnosis. |
Codes and their meaning can vary by model and production year, and the same code can have different causes. Where sources disagree we say so; in every case the exact cause is confirmed only by a technician's on-site diagnosis. Your owner's manual has the definitive list for your model.
Unplug the appliance (or switch off its breaker) before touching anything inside it, and never open a sealed refrigeration system, a gas valve or a microwave. If a code points to a part, the part has to be tested before it is replaced; we do that on the $75 diagnostic visit, credited toward the repair.
Switch it off at the breaker for a few minutes, then back on.
The leak sensor detected moisture in the base. Check hoses and let it dry.
