remains active after clearing
the restriction in the venting.
The display shows

Check filter indicator is on
during the drying cycle
Possible Causes & Solution
After clearing the restriction, the Flow Sense™ system requires
multiple, consecutive cycles to determine that the performance
value has improved before the Flow Sense™ indicator is reset.
• If the Flow Sense™ indicator remains active for more than five
cycles after the restriction has been cleared, call for service.
The duct work is about 75% - 95% blocked. ("d75", "d80", "d90"
or "d95" error code is displayed for 2 hours only)
• Do not use the dryer until the exhaust system has been cleaned
and/or repaired. Using the dryer with a severely restricted exhaust
is dangerous and could result in a fire or other property damage.
Check the outside dryer vent while the dryer is operating to make
sure there is strong airflow. If the exhaust system is extremely long,
have it repaired or rerouted.
House exhaust system blocked.
• Keep the area around the dryer clean and free of clutter. Check vent
hood for damage or lint clogging. Make sure the area around the
vent hood is clear.
Lint filter not cleaned properly.
• Remove the lint from the filter before every load. With the lint
removed, hold the filter up to a light to see if it is dirty or clogged. If
it looks dirty, follow the cleaning instructions. With some loads that
produce high amounts of lint, it may be necessary to clean the filter
during the cycle.
