Answer to continue safely
Is it safe to keep using?
Maybe. EF2 is a warning that airflow is restricted. While the dryer has safety systems to prevent overheating, continued use with poor airflow increases the risk of a vent fire and puts extra stress on the motor and thermostats. Clean the vent system as soon as possible.
Can I reset the code?
Yes. EF2 can be cleared by unplugging the dryer for a few minutes. However, it is a performance-based code and will return if the airflow restriction is not addressed. Cleaning the vent system is the proper fix.
When to stop immediately?
Stop if you notice: Stop using the dryer if you notice a burning smell, which could indicate lint near the heating element has begun to smolder., Do not use a leaf blower or compressed air to clean the vent; this can push lint deeper into the duct or damage the vent flap..
Symptoms You May Notice
EF2 code on display
The control panel shows EF2 during or at the end of a drying cycle, alerting you to restricted exhaust airflow.
Excessively long drying times
Loads that normally dry in 45 minutes now take 90 minutes or more because the moist air cannot escape efficiently.
Dryer exterior feels very hot
The top and sides of the dryer feel noticeably hotter than usual because heat is being trapped inside rather than exhausted.
Clothes hot but still damp
Clothes come out extremely hot to the touch yet remain damp because the saturated air is not being replaced with dry air.
Possible Causes
Lint-clogged exhaust vent duct
Lint has gradually accumulated inside the exhaust vent duct over months or years, narrowing the passage and severely restricting airflow.
DIY PossibleCrushed or kinked vent hose
The flexible transition hose between the dryer and the wall vent has been crushed by pushing the dryer too close to the wall or has developed a kink.
DIY PossibleBlocked exterior wall cap
The vent flap on the outside of the house is stuck closed, blocked by a bird nest, clogged with lint, or covered by snow or debris.
DIY PossibleSafe Checks You Can Do
-
1
Clean the lint screen and housing
Remove the lint screen and clean it thoroughly. Then use a long flexible brush to clean inside the lint screen housing slot, removing any buildup that the screen missed.
Vacuum the lint screen housing with a crevice attachment to remove fine lint particles that a brush may miss.

Clean the exhaust vent duct
Disconnect the vent hose from the back of the dryer. Use a dryer vent brush kit to clean the entire duct from the dryer connection point to the exterior wall cap.
Run the brush from both ends of the duct for the most thorough cleaning, especially on long vent runs.

3
Check the exterior wall cap
Go outside and locate the dryer vent wall cap. Verify the flap opens freely by hand and remove any lint, debris, or nesting material blocking it.
While the dryer runs on Air Fluff, you should feel strong airflow at the wall cap. Weak or no airflow confirms a blockage remains.
When to Call a Professional
Contact a qualified technician if:
- The exhaust vent duct has been cleaned but EF2 persists, suggesting a weak blower motor or damaged blower wheel.
- The vent run exceeds 25 feet or has more than two 90-degree elbows, making DIY cleaning insufficient.
- Lint is found inside the dryer cabinet around the drum and motor, indicating the exhaust system has been restricted for an extended period.
