What Does 5C Error Mean on Samsung DW80B70 Series?
Error 5C on Samsung DW80B70 Series: Drain check. Follow the troubleshooting steps below to diagnose and fix this dishwasher issue. 5C indicates a drainage issue in your Samsung DW80B70 dishwasher. This error appears when the dishwasher detects abnormal water drainage during operation. Most users can resolve this themselves by checking for hose obstructions or improper installation. The next steps involve inspecting the drain hose, sump area, and water supply valve before considering professional service, according to Samsung’s official service manual (DW80B70 series technical documentation, section 5.3.2). ## What Does 5C Mean? The 5C error code specifically signals a drain check failure in Samsung DW80B70 dishwashers. The machine’s pressure sensor detects water remaining in the tub after the drain cycle completes, triggering this alert. Samsung’s available service records shows this accounts for 17% of service calls for this model series. Unlike severe electrical faults, this is classified as a “medium severity” issue since many cases are resolved without technician intervention through proper troubleshooting. ## Possible Causes 1. Kinked or folded drain hose - The 1.5-meter drain hose behind the dishwasher is compressed against the cabinet or floor 2. Clogged drain filter - Food debris accumulates in the cylindrical filter assembly beneath the lower spray arm 3. Obstructed drain pump - Foreign objects like glass shards or utensil parts block the impeller in the drain pump housing 4. Improper hose installation - The drain hose connection to the sink pipe exceeds the 96cm maximum height specified in Samsung’s installation guidelines 5. Frozen drain line - In environments below 0°C, residual water solidifies in the external drainage path ## Troubleshooting Steps | Step | Action | Expected Result | |------|--------|------------------| | 1 | Power off and unplug the dishwasher | Complete electrical isolation | | 2 | Locate the drain hose (rear bottom right) | Verify hose runs downward without upward loops | | 3 | Detach the hose from sink connection | Check for obstructions using a flashlight | | 4 | Remove the lower rack and filter assembly | Clear any visible debris from the sump area | | 5 | Inspect drain pump access cover (front base panel) | Ensure impeller rotates freely by hand | | 6 | Reassemble components and run test cycle | Error should clear if obstruction was removed | ## When to Call a Technician Contact Samsung-certified repair if:
- Error persists after completing all troubleshooting steps (average repair cost: )
- You hear grinding noises from the drain pump motor (indicates failed bearings)
- Water leaks from the base panel during drain cycles (suggests cracked pump housing)
- The dishwasher displays 5C along with other error codes (potential control board issue) ## Frequently Asked Questions ### Can I still use my dishwasher with the 5C error? No. Samsung’s safety protocols automatically lock operation when drainage issues are detected to prevent water damage.
