Frequently asked questions

What does 1C / 1E mean on a Samsung washer?

On many model families, 1C / 1E indicates that the water-level sensor signal is abnormal. Confirm the exact model and region because the same display can be used differently.

Can I clear 1C / 1E by unplugging the washer?

A short power reset may clear a temporary state, but it will not fix a blocked hose, leak, failed sensor, motor, heater, or wiring fault. Stop if the code returns.

Should I replace a part based only on the code?

No. A code identifies a system or condition, not always the failed component. Complete safe external checks and use the model-specific manual or qualified service.

Keep diagnosing
