For the Samsung Washer families covered by the source set, **1 0C** means **overflow / excessive water error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. 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 0C**. Search normalization stores it as **10C** while preserving the characters a homeowner actually sees.

Quick answer
Overflow / excessive water error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 10C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Signs
Symptoms you may notice
Depending on the exact model, the appliance can enter a protective drain or stop condition.
On affected Samsung washing machine models, moisture can be present inside a base pan even when no puddle is visible outside.
The 1 0C display becomes more meaningful if the code can return after a fill, drain, defrost, ice-making, or water-dispensing event.
When the 1 0C condition is present, 1 0C appears during the washer stage associated with overflow / excessive water error.
The 1 0C display becomes more meaningful if the cycle may pause, stop, retry, drain, or refuse to advance until the condition is cleared.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Before opening any service area, stop use if water is near electrical parts or leaving the cabinet.
With 1 0C recorded, inspect only visible user-accessible hoses, filters, doors, gaskets, and water connections.
The next non-invasive check is to verify for excess suds where detergent is involved.
A safe owner-level check is to do not defeat or dry out a leak sensor repeatedly without locating why moisture reached it.
The next non-invasive check is to record the code and the cycle stage where it appears.
A safe owner-level check is to verify owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
Important safety warning. Safety takes priority over clearing 1 0C. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips.

When to request repair service
Persistent leak/overflow detection needs the moisture source corrected. Internal leak tracing, valves, sensors, pumps, or wiring may require service. If 1 0C keeps returning, record the stage at which it reappears so the technician can test the overflow / excessive water error path instead of replacing parts by guesswork.
Book your repair
Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **1 0C** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **1 0C**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
The code alone is not enough to justify a part. **1 0C** 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 **Washer 1 0C** separate from same-looking codes used by other Samsung appliance families.
