For the Samsung Dryer families covered by the source set, **CL1** means **laundry detected during vent test**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **CL1**. Search normalization stores it as **CL1** while preserving the characters a homeowner actually sees.

Quick answer
Laundry detected during vent test.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so CL1 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
For the Samsung Dryer families covered by the source set, **CL1** means **laundry detected during vent test**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **CL1**. Search normalization stores it as **CL1** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
A symptom that fits CL1 is that the display appears while the appliance is otherwise able to respond as expected.
CL1 can be accompanied by this pattern: the message may be tied to a mode, test, reminder, setup state, or protective condition rather than a failed part.
On affected Samsung dryer models, normal operation can resume after the documented mode or condition is cleared.
The CL1 display becomes more meaningful if cL1 appears on the display while the appliance reports: Laundry detected during vent test.

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 requesting service for CL1, confirm the exact display characters and appliance model before treating the message as an issue.
For CL1, start by doing this: check the user-facing setting, mode, door, filter, container, or setup condition named by Samsung for this display.
With CL1 recorded, use the model-specific manual to clear the status; avoid repeated resets if the message reappears unexpectedly.
The next non-invasive check is to record the code and whether the dryer is vented or heat-pump/ventless.
The next non-invasive check is to clean/inspect lint filter, heat exchanger, water tank/drain, and external vent only when relevant.
The next non-invasive check is to stop repeated resets if the code reappears; model-specific electrical/refrigeration diagnosis can be required.
Important safety warning. Stop for burning smell, smoke, gas odor, repeated breaker trips, or abnormal overheating. Do not bypass thermal protection. Do not bypass a safety device merely to see whether CL1 disappears.

When to request repair service
If the owner-accessible checks do not clear CL1, Service is not automatically required. Request diagnosis only if the status cannot be cleared as designed or normal operation does not resume. The repair should confirm the monitored function and its feedback before any board or component is condemned.

You can try the one reset Samsung documents for the model, but **CL1** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
Because **CL1** is not treated here as a conventional component failure, service is not automatically required. Clear or complete the documented mode and confirm that normal operation resumes.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **CL1** before replacing anything.
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 CL1** separate from same-looking codes used by other Samsung appliance families.
