Samsung Dishwasher Error Codes
Samsung dishwashers display LC leak, OC overflow, 4C fill, and HE heat errors. WaterWall models add extra motor codes.
General troubleshooting
Try these checks before opening a specific error code page—they resolve many Samsung dishwasher faults without parts.
- 1Inspect door gasket and bottom of the door for food debris causing leaks
- 2Clean the fine and coarse filters in the tub sump
- 3Check the drain hose connection at the sink air gap or disposal
- 4Run Normal cycle with Samsung dishwasher cleaner on DW80CG5451SR
- 5Ensure the unit is level left-to-right and front-to-back
Common symptoms
Owners often search for a code after noticing one of these issues on their Samsung dishwasher:
- LC or leak sensor triggered with water under the unit
- OC or over-level when the fill valve sticks open
- 4C slow fill at cycle start
- HE heat fault with cold dishes after the dry cycle
- Heavy noise at drain on DW80 and DW50 series
All Samsung dishwasher error codes
| Code | What it means | Guide |
|---|---|---|
| 3C | Wash motor position sensor fault3C on Samsung dishwashers indicates the wash motor position sensor did not report expected rotor alignment—the circulation motor cannot start wash spray until the hall sensor confirms position. | View fix → |
| 4E | Water supply not reaching the tub4E is a fill timeout—Samsung opened the inlet valve but the flow meter or level switch never confirmed enough water entered within the programmed window. The cycle stops before wash. | View fix → |
| 5C | Drain timeout with water remaining5C is Samsung's drain fault—the pump ran but water level remained high after the drain window. Same family as 5E display variant; water stays in the tub bottom and the cycle stops before dry. | View fix → |
| 5E | Drain cycle timed out with water in tub5E appears when the drain pump runs but the water level sensor still reads high after the allotted drain window. Samsung halts before dry and may leave standing water at the bottom of the tub. | View fix → |
| 7E | WaterWall reflector blocked or misinstalled7E (7C variant) flags the WaterWall reflector stuck on its shuttle—the linear wash arm that moves along the bottom rail. Samsung pauses wash when the position sensor sees no travel, common on first use if shipping tape remains. | View fix → |
| AE | Communication fault on control boardsAE indicates the main power board lost reliable communication with a sub-module—touch UI, diverter driver, or Wi-Fi board. Cycles may freeze with lights flashing and no progress. | View fix → |
| BE | Touch panel button sensed as stuckbE reports a button held continuously on the touch interface—Samsung stops all functions until the key matrix clears. Common after liquid runs down the glass during cleaning. | View fix → |
| CE | Over-temperature or inlet water too hotCE on Samsung dishwashers frequently groups with 4C2—extremely hot water entering the cold inlet because supply hoses are swapped. The board aborts fill to protect seals and plastic sump components. | View fix → |
| DE | Door not latched or switch opendE halts the cycle because the door switch never confirmed closed—Samsung will not fill or energize wash motor with an open door circuit. Child lock combinations can mimic dE on some models. | View fix → |
| FE | Line frequency or power anomalyFE is a Frequency Error—the control detects mains frequency outside expected range or the sensing circuit failed. Often appears alongside voltage faults after outages or on shared kitchen circuits. | View fix → |
| HE | Wash water not reaching heat targetHE on Samsung rotary-spray models indicates the water did not reach target temperature during wash—often the flow-through heater, thermistor, or incoming water was too cold. WaterWall models may map HE differently; check your manual. | View fix → |
| IE | Clogged filter or water not passing screenIE (1E) on WaterWall dishwashers signals water cannot pass through the fine filter assembly—restricted flow before the wash pump. Rotary models may display IE for high-temperature heater faults instead; confirm against the sticker inside the door. | View fix → |
| LC | Leak sensor wet in the base panLC is Samsung's Leak Code—the styrofoam float in the base pan detected water. The inlet valve shuts immediately and the display shows LC to keep water off your floor. LE on older firmware is the same fault. | View fix → |
| OC | Water level too high in the tubOC is Over Level water—the level sensor read high when the control expected normal wash depth, or water kept entering after shutoff. Samsung may run the drain pump continuously trying to lower the level. | View fix → |
| OE | Overfill—too much water in the tubOE reports the water level above the safe threshold—often inlet valve stuck open, failed float switch, or suds mimicking high level. Samsung stops fill and may run drain to protect the kitchen floor. | View fix → |
| PC | Zone wash or half-load position faultPC flags a Position Error on Samsung dishwashers with movable wash zones—Zone Booster or WaterWall reflector systems. The control commanded travel along the bottom rail but the position sensor never confirmed the expected location. | View fix → |
| PE | Half-load diverter or spray arm faultPE is a motor Position Error in half-load mode—the diverter assembly did not switch the inner spray arm path when commanded. Full-load cycles may still work; PE often appears only when Half Load is selected. | View fix → |
| SE | Drain error variant of 5E familySE displays the same drain fault as 5E and 5C on Samsung firmware variants—the pump ran but water level did not fall below the sensor threshold in time. Letter S versus numeral 5 is display formatting only on many units. | View fix → |
| TE | Temperature sensor signal invalidtE means the wash thermistor sent resistance outside Samsung's valid band—open, shorted, or drifting. Sanitize and heavy cycles abort because the board cannot confirm safe water temperature. | View fix → |
