Error codeC80, C8, C8o

These three codes are an outcome of the Vent Blockage test and nothing else. They put the vent at about four-fifths clogged, which is a measurement, not a breakdown of the dryer.
What to clean
The lint filter.
The exhaust vent.
Afterwards, repeat the test and compare the outcome.
When cleaning does not change the result, Samsung dryer repair supports San Francisco and Bay Area owners at (415) 969-6153. Share the code, the model number and which parts you cleaned.
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
Vent blockage test result: about 80% of the vent is blocked.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
Seven readings on a Samsung dryer, from dC to 1 dF, share one theme: the door is not confirmed as shut and latched. Work through the latch and door checks.
You submit a request with your appliance model and symptom, we confirm an appointment window, and a technician performs an on-site diagnosis. You then receive a clear estimate and decide whether to proceed before any repair begins.
Yes. We provide an upfront estimate after diagnosis. No parts are ordered or installed until you approve the work, so there are no surprise charges.
