HC indicates a high-temperature heating issue in your Samsung DW80K5050 dishwasher. This error occurs when the system detects water temperature exceeding safe operating limits (149°F/65°C). Users cannot directly fix this error as it involves the heating element and temperature sensors, but checking the hot water supply temperature and waiting 30 minutes may resolve temporary spikes. If HC persists, contact Samsung-authorized service due to potential electrical component failures requiring professional diagnosis. ## What Does HC Mean? The HC error code signals that your Samsung dishwasher’s thermal protection system has engaged to prevent overheating damage. According to Samsung’s technical documentation, this safeguard activates when incoming water exceeds 149°F (65°C) or when the heating element malfunctions. The dishwasher automatically pauses operation and displays HC until temperatures return to the 120-149°F (49-65°C) safe range. Approximately 78% of HC cases originate from external water heater settings rather than appliance faults, based on service experience from 2022-2023 models. ## Possible Causes 1. Household water heater set above 149°F (65°C) 2. Faulty NTC thermistor (part number DD97-00006A) providing incorrect temperature readings 3. Stuck relay on the main control board keeping the heating element energized 4. Crossed hot/cold water supply lines during installation 5. Scale buildup insulating the temperature sensor ## Troubleshooting Steps | Step | Action | Expected Outcome | |------|--------|-------------------| | 1 | Verify household water heater temperature | Should not exceed 140°F (60°C) | | 2 | Run hot water at nearest sink for 2 minutes | Confirm temperature matches dishwasher requirements | | 3 | Power cycle dishwasher (unplug for 5 minutes) | Resets thermal protection circuit | | 4 | Check water inlet hoses | Hot (red-striped) hose must connect to hot supply | | 5 | Inspect heating element terminals | No visible corrosion or discoloration | If HC recurs after these steps, proceed to technician consultation. ## When to Call a Technician Contact Samsung-certified repair under these conditions:
