Safety notice
Safety: Do not attempt live electrical testing, bypass safety switches, or open sealed refrigeration systems. If you are unsure, call a professional.
Safe homeowner checks
- Power cycle the appliance (turn off/unplug for 60 seconds, then restart).
- Confirm the breaker is fully on (some appliances use two linked breakers).
- Check for obvious blockages (filters, drain hose kinks, lint buildup) where applicable.
- If the code returns, take a photo of the display and note when it appears (start, mid-cycle, heating, draining) — it helps diagnose dishwasher issues faster.
Stop DIY and call a technician if…
- You smell burning, see smoke, or notice sparking.
- There is active leaking or water near electrical components.
- The appliance is overheating or repeatedly trips the breaker.
- The error code returns immediately after basic checks or the unit will not run safely.
Error Codes by Brand
Samsung Dishwasher Error Codes
Samsung appliance repair in Ottawa
| Error Code | What It Usually Means | Safe Homeowner Check | When to Call Fixer |
|---|---|---|---|
| 4E / 4C | The dishwasher is not filling within the time the control allows, or inlet flow is too low. | Confirm the water supply tap under the sink is fully open and the inlet hose is not kinked. Cancel the cycle and avoid stacking repeated starts. | If filling stays slow, Fixer can test the inlet valve, float or pressure switch, wiring, and control output. |
| 5E / 5C | Water is not draining from the tub at the expected rate. A blocked filter or drain path is a common contributor. | Remove and rinse the bottom filter assembly if your model allows. Check the sink drain connection and garbage disposal knockout. Do not run another cycle with standing water in the tub. | If water remains after basic cleaning, a technician can inspect the drain pump, hose routing, and control signals. |
| LC / LE | A leak or moisture was detected in the base pan. The dishwasher may stop to limit water damage. | Turn off the water supply under the sink, cancel the cycle, and dry visible water at the door and base. Check the door seal for debris. | Active leak codes should be diagnosed promptly. Fixer can trace fill valves, hose connections, pump seals, and tub integrity. |
| OC / oE | The dishwasher detected overfill, excess water entering the tub, or a drain timeout during the cycle. | Shut off the water supply, cancel the cycle, and watch for active inlet leaking. Use the recommended detergent amount. | If overfill or drain timeout continues, book diagnosis for inlet valves, float or pressure sensing, and drain function. |
| HE | The heating circuit did not reach the expected temperature during wash or dry stages. | Use a normal hot-water cycle and confirm hot water at the kitchen tap first. Avoid running heated dry repeatedly while the code is present. | Heater, thermostat, and control-board faults need proper testing. Fixer can check the heating circuit safely on electric dishwashers. |
| tE | A thermistor or water temperature sensor reading is out of range, which can affect wash and dry performance. | Confirm hot water is available at the sink before starting a cycle. Run one standard wash without heated dry and note when the code appears. | If tE returns, Fixer can test the thermistor, wiring, and control-board inputs before the sensor or board is replaced unnecessarily. |
| 7E | A waterwall or spray-arm movement fault was detected, which can affect wash distribution on some Samsung dishwasher models. | Check that racks and dishes are not blocking the spray path. Cancel the cycle and restart once after clearing obstructions. | If 7E returns with a clear spray path, Fixer can diagnose the spray mechanism, motor, sensor, wiring, or control before parts are replaced. |
