The **1C** display on a Samsung washing machine points to **water level sensor error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **1C**. Search normalization stores it as **1C** while preserving the characters a homeowner actually sees.

Water level sensor error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 1C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Important safety warning. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips. Do not bypass a safety device merely to see whether 1C disappears.
If the code returns, model-specific sensor, harness, connector, and control-board testing is appropriate. If 1C keeps returning, record the stage at which it reappears so the technician can test the water level sensor error path instead of replacing parts by guesswork.

Water level sensor error.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **1C** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **1C** should not be ignored if performance is deteriorating or the display keeps returning.
No. **1C** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
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 1C** separate from same-looking codes used by other Samsung appliance families.
