If a Samsung washing machine shows **1 5C**, the verified Samsung meaning in this research set is **drainage error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. 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 5C**. Search normalization stores it as **15C** while preserving the characters a homeowner actually sees.

Quick answer
Drainage error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 15C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
If a Samsung washing machine shows **1 5C**, the verified Samsung meaning in this research set is **drainage error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. A display code is evidence from the control system, not a component test result.

Signs
Symptoms you may notice
On affected Samsung washing machine models, water or condensate may remain where the appliance expects it to be removed.
1 5C can be accompanied by this pattern: a cycle can pause, extend, or stop during the drain stage.
1 5C can be accompanied by this pattern: a pump may run longer than normal or sound different while the code is active.
The 1 5C display becomes more meaningful if 1 5C appears during the washer stage associated with drainage error.
One clue that supports the 1 5C diagnosis is that the cycle may pause, stop, retry, drain, or refuse to advance until the condition is cleared.

Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
With 1 5C recorded, inspect and clean only the user-accessible filter or drain area described in the model manual.
For 1 5C, start by doing this: check the external drain hose for kinks, freezing, crushing, or an incorrect installation height.
For 1 5C, start by doing this: verify the household standpipe, sink, disposal connection, or condensate path is not restricted.
The next non-invasive check is to record whether the pump runs and whether fluid actually leaves the appliance.
To rule out an accessible cause, record the code and the cycle stage where it appears.
For 1 5C, start by doing this: verify owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
Important safety warning. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips. If resolving 1 5C would require energized internal access, that is the point to hand the diagnosis to a qualified technician.

When to request repair service
If the accessible drain path is clear but the code returns, the pump, internal hose, water-level sensing, wiring, or control may need model-specific testing. A repeatable 1 5C event is more useful diagnostically than repeated resets, because it shows when the drainage error check is failing.

Resetting can clear a temporary state, not a persistent issue. If **1 5C** comes back, preserve the code and move to the safe checks or model-specific service path.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **1 5C** should not be ignored if performance is deteriorating or the display keeps returning.
The code alone is not enough to justify a part. **1 5C** 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 5C** separate from same-looking codes used by other Samsung appliance families.
