Signs
Symptoms you may notice
On affected Samsung dishwasher models, heating can be weak, absent, excessive, or stop unexpectedly.
One clue that supports the HC2 diagnosis is that the appliance can pause when the control detects an unsafe or implausible temperature condition.
HC2 can be accompanied by this pattern: drying, washing, cooking, or defrost performance can change depending on the appliance.
On affected Samsung dishwasher models, hC2 appears during the dishwasher function associated with drying / vent heating error.
HC2 can be accompanied by this pattern: the cycle can stop, drain, fail to fill/heat, or repeat a stage.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
With HC2 recorded, confirm the selected cycle or cooking mode is supposed to use heat.
To rule out an accessible cause, check airflow, vents, filters, water supply, or door closure when those conditions affect temperature.
For HC2, start by doing this: allow the appliance to cool before any owner-accessible inspection.
With HC2 recorded, do not open energized high-voltage or heating sections.
For HC2, start by doing this: record the code before resetting.
For HC2, start by doing this: check water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
Important safety warning. Stop use for active leakage near electrical parts, burning smell, or repeated breaker trips. Do not defeat leak or door-safety switches. For HC2, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.

When to request repair service
Once HC2 has returned after the safe checks, A returning heating/over-temperature code after external checks requires model-specific testing of sensors, heaters/ignition, relays, wiring, airflow, or control electronics. Preserve any accompanying noise, water level, temperature, or operating-stage details for the technician.

You can try the one reset Samsung documents for the model, but **HC2** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **HC2** should not be ignored if performance is deteriorating or the display keeps returning.
The code alone is not enough to justify a part. **HC2** should narrow testing to the affected function; the final cause still has to be verified on the exact model.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Dishwasher HC2** separate from same-looking codes used by other Samsung appliance families.
