Match the symptom, then work through the safe checks.
1. What best matches what you observe?
2. Complete only the checks that are safe for you.
Show stop conditions
- HC2 returns after the single Samsung power-cycle attempt
- Burning odor, smoke, unusual heat, or breaker trips occur
- Diagnosis would require access to the drying heater, sensor, relay, wiring, or control board
Likely causes
- The drying heater is not operating within the expected temperature range
- Drying-air temperature sensing is abnormal
- The drying heater circuit, relay, wiring, or control has a fault
- The code is being read from a model family that uses HC2 differently, so the exact model manual must be checked
Quick checks, in order
Confirm the machine has a drying function
HC2 is documented by Samsung on supported washer-dryer/FlexWash families for the drying-heater side. If the appliance has no drying function, verify the exact code and model before using this guide.
Note whether HC2 appears during drying
Record whether the wash portion completes and the code appears only when heated drying begins; that distinction separates HC2 from ordinary wash-heater faults.
Power-cycle once
Follow Samsung's user-level guidance: power the appliance off for about 2–3 minutes, restore power, and retry once.
Stop before drying-heater electrical tests
Heater resistance, relay, wiring, sensor, and live-voltage tests require qualified service. Do not remove panels for energized testing.
Is HC2 tied specifically to the drying stage on a washer-dryer model?
That pattern matches Samsung's washer-dryer HC2 context. Stop repeated retries if the code returns after one power reset and arrange model-specific service.
Do not assume this FlexWash definition applies. Recheck the display and exact model manual because Samsung code meanings vary by product family.
Stop using the appliance and disconnect power if safe. Treat this as an electrical/heating safety issue rather than continuing reset attempts.
Stop and get qualified help when
- HC2 returns after the single Samsung power-cycle attempt
- Burning odor, smoke, unusual heat, or breaker trips occur
- Diagnosis would require access to the drying heater, sensor, relay, wiring, or control board
Official support and model manuals
Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
Is Samsung HC2 the same as Hr?
No. Samsung documents HC2 on supported FlexWash/washer-dryer families as a drying-heater fault, while Hr appears in washer heater/heater-relay guidance. Always confirm the exact model because Samsung reuses code families across products.
Can a normal washer without a dryer use this HC2 guide?
Not safely by assumption. This page is intentionally scoped to Samsung washer-dryer/FlexWash families where Samsung documents HC2 for the drying heater. Check the exact model manual if the machine has no drying function.
Should I replace the drying heater based only on HC2?
No. The code identifies a heating-system condition, not necessarily the failed part. Sensor, wiring, relay, control, or heater diagnosis must be model-specific.
