If a Samsung dryer shows **Et**, the verified Samsung meaning in this research set is **communication error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. The useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The recorded display form is **Et**. Search normalization stores it as **ET** while preserving the characters a homeowner actually sees.

Communication error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so ET 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. Stop for burning smell, smoke, gas odor, repeated breaker trips, or abnormal overheating. Do not bypass thermal protection. For Et, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.
A returning communication/electronic-control code can require harness, connector, board power-supply, firmware, or module testing. If Et keeps returning, record the stage at which it reappears so the technician can test the communication error path instead of replacing parts by guesswork.

Communication error.
A single documented power reset can help after an external condition or power event is corrected. If **Et** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **Et**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
The code alone is not enough to justify a part. **Et** 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 **Dryer Et** separate from same-looking codes used by other Samsung appliance families.
