Samsung Washer code **1 HC** is associated with **water-temperature / heating-system error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **1 HC**. Search normalization stores it as **1HC** while preserving the characters a homeowner actually sees.

Quick answer
Water-temperature / heating-system error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 1HC may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Samsung Washer code **1 HC** is associated with **water-temperature / heating-system error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **1 HC**. Search normalization stores it as **1HC** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
A symptom that fits 1 HC is that heating may be weak, absent, excessive, or stop unexpectedly.
When the 1 HC condition is present, the appliance can pause when the control detects an unsafe or implausible temperature condition.
Depending on the exact model, drying, washing, cooking, or defrost performance may change depending on the appliance.
Depending on the exact model, 1 HC appears during the washer stage associated with water-temperature / heating-system error.
On affected Samsung washing machine models, the cycle may pause, stop, retry, drain, or refuse to advance until the condition is cleared.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Before requesting service for 1 HC, confirm the selected cycle or cooking mode is supposed to use heat.
A safe owner-level check is to check airflow, vents, filters, water supply, or door closure when those conditions affect temperature.
Before opening any service area, allow the appliance to cool before any owner-accessible inspection.
Before opening any service area, do not open energized high-voltage or heating sections.
With 1 HC recorded, record the code and the cycle stage where it appears.
The next non-invasive check is to verify owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
Important safety warning. When working around a washing machine that shows 1 HC, keep the checks external and non-invasive. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips.

When to request repair service
For 1 HC, the service threshold is straightforward: A returning heating/over-temperature code after external checks requires model-specific testing of sensors, heaters/ignition, relays, wiring, airflow, or control electronics. Bring the exact model number and a photo of the display so the diagnosis stays tied to the documented Samsung code.

Resetting can clear a temporary state, not a persistent issue. If **1 HC** comes back, preserve the code and move to the safe checks or model-specific service path.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **1 HC**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **1 HC** before replacing anything.
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 **Washer 1 HC** separate from same-looking codes used by other Samsung appliance families.
