C1/CL1 belongs to the vent-test setup check for laundry detected in the drum. Empty the drum and repeat the model’s test; if it occurs with an actually empty drum, Samsung directs service.
Samsung vent-test models using C1/CL1. This is not a washer code or a general Child Lock message.
Stop for smoke, burning smells, abnormal heat or repeated breaker trips. Let the dryer cool before cleaning. Do not expose wiring, bypass interlocks or work on gas components. If gas is smelled, leave and call the utility or emergency services from a safe location.
Compare the behavior
Read C1/CL1 in the context of the vent test. Confirm the drum was empty and the test was started as directed. Do not treat a test setup message as a Control Lock warning or an ordinary drying-cycle fault.
| Observed state | Interpretation / next step |
|---|---|
| Laundry remains during test | Empty and repeat correctly. |
| Empty drum, same C1/CL1 | Request service. |
| CL outside a vent test | Verify lock status with the exact manual. |
Code-specific checks
Check the test context
Write down whether you intentionally entered Vent Blockage Test. Photograph C1/CL1 instead of assuming it is CL. Similar characters can send the owner toward a lock combination when the actual issue is a failed installation check.
Remove everything for the retest
Empty garments and other objects, including a removable drying rack if the manual requires an empty drum. Let the appliance reach the documented test condition and follow its exact entry procedure. This is a setup correction, not a request to increase cycle time.
When empty really means empty
If C1/CL1 returns, provide the full model and a photo of the empty drum with the code to service. Do not defeat the door switch, enter a technician-only menu or assume a sensor replacement from the characters alone. The manufacturer’s owner procedure ends at a persistent empty-drum result.
If the warning returns
Correct the setup once; persistent C1/CL1 with an empty drum needs service.
When to stop and get help
Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
