Appliance Dryer
Quick answer

C80, C8 and C8o show after a Vent Blockage test and mean the vent is about four-fifths clogged.

Model compatibility: Samsung reuses codes across series and model years, so C80 / C8 / C8o may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

C80 (also C8, C8o) is a Vent Blockage test result: about four-fifths of the vent is blocked.

Run the Vent Blockage test on a Samsung dryer and it may finish with C80, C8 or C8o. That result says about four-fifths of the vent is clogged. These codes appear only after the test.

What Samsung says to do

Clean your lint filter and your exhaust vent. Then run the test again to see the new result.

Other vent results

  • C90: over nine-tenths of the vent clogged.
  • Clg: the vent is clogged.
  • C1: laundry found in the drum.
