Samsung Dishwasher Error Code Service Companion
A Samsung dishwasher may display different code versions for the same operating problem, depending on the model and control panel. Codes such as 4C or 4E point to water supply trouble, while 5C, SC, 5E, or SE indicate that used water is not leaving the tub correctly.
This guide organizes the provided Samsung dishwasher codes into practical fault families for San Diego homeowners. Reset Appliance Repair provides local help for dishwashers that will not fill, circulate, drain, heat, detect water levels, or complete a normal wash program.
How Samsung Dishwasher Codes Narrow the Problem
A code identifies the system that detected abnormal operation, but it does not prove that one component has failed. A drain alert may come from the hose, filter, sump, pump, or sink connection. A heating code may involve water temperature, a sensor, the heater, wiring, or electronic controls.
Model design also matters. On Waterwall models, 1E or IE commonly refers to restricted water flow through the filter. On rotary models, the same display may indicate excessive internal temperature. The complete model number should therefore be checked before parts are selected.
Main Samsung Dishwasher Water Fault Family
Filter, Supply, Drain, Leak, and Overflow Codes: 1E / IE / 4C / 4E / 5C / SC / 5E / SE / LC / LE / OC / 0C / oE
This is the largest family because water must enter correctly, circulate through the wash system, and leave the appliance after each stage.
On Waterwall dishwashers, 1E / IE means water is not passing through the fine filter correctly. A clogged filter can interrupt circulation and stop the program. On rotary models, these codes can indicate excessive internal temperature, so the model type must be confirmed first.
The 4C / 4E codes identify a water supply problem. The valve may be closed, the inlet hose may be kinked, or the appliance may not be receiving the pressure or temperature it expects.
The 5C / SC / 5E / SE group means the dishwasher cannot drain. Water may remain above the filter, the appliance may keep trying to pump out, or the program may stop before drying. Visible drain connections, the filter, sump area, and hose should be checked for restrictions.
The LC / LE codes mean the leak sensor has detected moisture. The dishwasher may switch itself on and run the drain pump continuously. OC / 0C / oE means the water level is higher than expected. If water continues entering, turn off the household water supply.
Other Samsung dishwasher fault groups may also appear:
Pump and Waterwall Movement Codes: 3C / 7E
The 3C code indicates a pump operation fault. The dishwasher may fill but fail to begin active spraying. The 7E code applies to the Waterwall reflector, which cannot move correctly when blocked, incorrectly positioned, or affected by packing material.
Water Temperature and Level Codes: 3E / 9E
The 3E code means the incoming water is too hot. Samsung advises keeping the hot-water supply below 176°F. The 9E code indicates that the dishwasher has detected insufficient water inside the tub.
Button and Communication Codes: bE / 6E / CE
The bE / 6E family appears when the control panel detects a stuck button. Moisture, residue, or a damaged key may cause repeated input. The CE code means the control panel cannot communicate properly with the rest of the dishwasher.
Heating and Temperature-Sensing Codes: HC / HE / tE
The HC code identifies an excessive-temperature heater condition. HE means heating temperature is being detected incorrectly, while tE points to a temperature-sensor fault. These alerts may interrupt washing or drying to protect the appliance.
Zone Wash and Half-Load Codes: PC / PE
The PC code means the Zone Wash function is not operating correctly. The PE code concerns the half-load function.
What San Diego Homeowners Should Check First
Write down the complete code before turning off power. Check the filter, visible hoses, water valve, detergent type, standing water, door area, and whether any button is stuck. Samsung advises troubleshooting the likely cause before clearing the code, since a reset alone may not correct it.
Stop using the appliance if water is leaking, the pump runs continuously, the interior becomes unusually hot, or the same code returns after one controlled restart.

Samsung Dishwasher Error Code Meanings and Recommended Actions
The table explains Samsung dishwasher codes for water supply, drainage, leaks, overflow, pump operation, Waterwall movement, temperature sensing, heating, control communication, and wash functions. It also accounts for model-dependent code meanings and provides the recommended checks for each displayed message before professional diagnosis is required.
| Error Code | Meaning | Safe first steps | Technician required | Related help |
|---|---|---|---|---|
| 1E / IE | Waterwall models: clogged filter error. Rotary models: high temperature heater error. | Waterwall models: clean the fine filter. Rotary models: power the dishwasher off for 30 seconds at the breaker, empty it, add detergent, and run a Normal cycle. | Yes — if the code returns. | |
| 3C | Pump operation error. | Turn the dishwasher off and try to start the cycle again. | Yes — if the error still occurs. | |
| 3E | High temperature water supply error. | Verify the incoming hot water supply is not above 176°F. | Yes — if the supply temperature is normal but the error remains. | |
| 4C / 4E | Water supply error. | Perform Samsung's safe water-supply checks for pressure, hose routing, valve position, and supply temperature. | Yes — if the dishwasher still cannot fill correctly. | |
| 5C / SC / 5E / SE | Drain error. | Perform Samsung's safe drain troubleshooting, including checking the drain hose / air gap / sink connection for simple blockages. | Yes — if the drain problem remains. | |
| 7E | WaterWall reflector error. | Check Samsung's WaterWall reflector guide for blockage or misalignment and correct any simple obstruction. | Yes — if the reflector still cannot move correctly. | |
| 9E | Low water level error. | Empty the dishwasher, add detergent, and run a Normal cycle. If needed, shut off power at the breaker before further service. | Yes — if the error still occurs. | |
| bE / 6E | Button error / stuck key. | Turn the dishwasher off and press each button on the panel to confirm none is stuck. | Yes — if buttons do not work correctly or the code returns. | |
| CE | Communication error. | Turn the dishwasher off and try to start it again. | Yes — if the error continues. | |
| HC | High temperature heater error. | Power the dishwasher off for 30 seconds at the breaker, empty it, add detergent, and run a Normal cycle. | Yes — if the error occurs again. | |
| HE | Heater / temperature detection error. | Empty the dishwasher, add detergent, and run a Normal cycle. If needed, shut off power at the breaker before service. | Yes — if the error still occurs. | |
| LC / LE | Leakage error / moisture detected by leak sensor. | Follow Samsung's leak-error checks, including looking for simple external leaks and (on WaterWall models) checking for a blocked reflector. | Yes — if the leak error persists. | |
| OC / 0C / oE | Over-level water error. | Perform Samsung's drain / overflow troubleshooting and verify the dishwasher can drain properly. | Yes — if the overfill condition returns. | |
| PC | Zone Wash error. | Turn the dishwasher off and try to start the cycle again. | Yes — if the error still occurs. | |
| PE | Half load function error. | Empty the dishwasher, add detergent, and run a half-load cycle. If needed, shut off power at the breaker before service. | Yes — if the error still occurs. | |
| tE | Temperature sensor error. | Empty the dishwasher, add detergent, and run a Normal cycle. If needed, shut off power at the breaker before service. | Yes — if the error still occurs. |
