The Samsung DVE45T6000 has a built-in Vent Blockage Test that gives a vent code. With the drum empty and the dryer cool, press Power, hold Adjust Time and Dryness for 3 seconds until InS shows, then hold Start; the test takes about 2 minutes. A 0 means the vent is fine, Clg (Cg) means it is clogged, C80 (C8) means about 80 percent blocked, C90 (C9) means over 90 percent blocked and needs expert cleaning, and Ct means the drum was too cold or too hot to test. Clean the lint filter and the duct, then test again.
Differential
Likely causes of “Samsung dryer shows a vent, airflow or blockage warning”, and how to tell them apart
- 1
Lint packed in the duct or outside hood
What separates it C80 or C90 shows and the drying times are long because lint is packed in the duct or outside hood
How to confirm Disconnect and clean the duct, and clear the hood flap
- 2
A crushed, kinked or overlong duct run
What separates it The test shows Clg even with a clean filter
How to confirm Straighten the duct and check its length against the elbow table
- 3
Flexible plastic duct or a lint-trapping screw
What separates it A duct that sags or a screw tip inside the duct
How to confirm Replace it with 4 inch rigid metal duct, taped at every joint
- 4
The test was run with a hot or cold drum
What separates it Ct shows because the dryer is below 32 F or over 104 F
How to confirm Leave the dryer between 41 and 95 F for an hour, then test again
Before you touch a setting
Record this first — changing settings destroys the evidence
- The exact check code shown after the 2 minute test
- The length and number of elbows in the duct run
- Whether the outside hood flap opens freely when the dryer runs
Try in this order
0 of 5 completedEmpty and cool the dryer
ReversibleRemove all clothes, close the door and let the drum cool. The manual says the test must run when the dryer is cool; if it has warmed up, run Air Fluff for a few minutes first.
Enter the test
ReversiblePress Power, then hold Adjust Time and Dryness together for 3 seconds. InS appears. If you started another procedure first, the dryer will not enter the test.
Run and read the test
ReversibleHold Start/Pause. The number indicator circles in 6 steps for about 2 minutes. When it finishes a tone sounds and the result shows for about 5 minutes, or press Power to clear it.
Clean the filter and duct
ReversibleFor Clg or C80, clean the lint filter and check the vent. For C90, Samsung says expert personnel must clean it. Check for kinks, crushed sections and lint at the hood.
Test again
ReversibleAfter cleaning, run the test again. Even a 0 result can hide a partly blocked vent, so also check the ducting against the manual's length table.
Model-specific
What is true of this model and not of its siblings
- Exhaust rules from the manual
- The dryer must vent outside, never into a chimney, wall, ceiling, attic, crawl space or concealed space. The exhaust duct is 4 inches (10.2 cm) in diameter, flexible metal duct must not exceed 7 ft 10 1/2 in in total, duct must be fastened securely, and no screws or fasteners may extend into the duct where they catch lint.

Stop boundary
When this stops being a self-service repair
- !If the test shows C90 (over 90 percent blocked), stop using the dryer until the duct is cleaned by qualified personnel
- !If the duct is clean and straight but Clg persists, contact a Samsung service center

Exact questions
Common questions
How do I start the Vent Blockage Test?+
With the drum empty and cool, press Power, hold Adjust Time and Dryness for 3 seconds until InS appears, then hold Start/Pause.
What do C80 and C90 mean?+
C80 is about 80 percent of the vent clogged and C90 is over 90 percent. C90 needs expert cleaning.
Is a result of 0 always perfect?+
No. The manual says even 0 can hide a slight blockage, so install all ductwork exactly as the installation section says.
What does Ct mean?+
The internal temperature is below 32 F or above 104 F, so the vent check cannot be trusted. Leave the dryer at 41 to 95 F for an hour.
How long is the test?+
About 2 minutes. Do not open the door during it.
Can I cancel the test?+
Press Power to stop or cancel it. A suspended test may give incorrect results.
