Vent blockage test
After the dryer is installed, start the Vent Blockage Test to check if the duct system is properly installed.
The Vent Blockage Test automatically detects the status of the ducts and reports any blockage or problems.
Proper ducting can reduce drying time and save energy.
NOTE
The Vent Blockage Test must run when the dryer is cool. If the dryer warms up after the installation check,
run the AIR FLUFF cycle for several minutes to reduce its internal temperature.
Running the vent blockage test
1. Make sure the drum is empty, and then close the door. (If there are any clothes or other items in the
drum, the test will not give accurate results.)
2. Press the POWER button to turn the dryer on, then simultaneously press and hold the Time and START/
PAUSE buttons for 3 seconds. "InS or In" appears in the dryer's display. (If you have started other
procedures before the Vent Blockage Test, the dryer will not enter the Vent Blockage Test mode.)
3. Press the START/PAUSE button. The Vent Blockage Test starts immediately. During the test, the number
indicator makes a circle in 6 clockwise steps. The test takes about 2 minutes. Do not open the door
during the test.
4. After 2 minutes, when the test is complete, the results are displayed and the dryer sounds a tone. If
status of the duct system is normal, "End or 0" appears and the dryer sounds a completion tone. If the
duct system cannot exhaust properly, the check code appears, and the dryer sounds an alarm tone. For
description about the code, see the "Installation check codes" section on page 28.
If there are any other problems, an information code appears in the display. For description about the
code, see the "Information codes" section on page 43.
-
To stop or cancel the Vent Blockage Test, press the POWER button to turn off your dryer.
-
The results remain on the display for about 5 minutes and then automatically turn off. You can turn
the results off immediately by pressing the POWER button.
NOTE
• During or after the test, the internal drum is hot. Use caution to prevent burns. The Vent Blockage Test
is used to check for problems in the current duct system when the dryer is installed for the first time.
• If the test result displays check code (the duct system is blocked ), refer to the "Ducting requirements"
section on page 14 and the "Exhaust ducting guide" section below, and then take proper measures to
correct any problems. If the test is suspended, it could result in incorrect results. Follow the proper
procedures when testing the dryer.
• Even if the test result is normal ("End or 0"), the duct system could be blocked slightly. Properly install
all duct work according to the installation instructions in this manual.
