Samsung Dryer Error Code Clg
This is not a breakdown but the result of the dryer's Vent Blockage test: exhaust air is not getting out freely, and C80 or C90 tell you roughly how blocked the vent is. A thorough clean of the screen, hose, and duct run is the fix, and it removes a genuine fire risk at the same time.
Also shown as: Cg, Cl9, C9, C80, C8, C90
Common causes
- Lint built up inside the vent duct run
- Vent hose crushed or kinked behind the dryer
- Outside vent hood blocked, or its flap stuck shut
- Lint screen clogged with residue
What to check, in order
- Clean the lint screen, and wash it if a film has built up on the mesh.
- Check behind the dryer that the vent hose is not crushed or sharply kinked.
- Disconnect the vent hose and clear the accumulated lint out of the hose and the duct run to the outside.
- Go outside while the dryer runs and confirm strong airflow comes out of the vent hood and its flap opens fully.
- Re-run the Vent Blockage test to confirm the result has cleared.
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code Clg, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
