This air flow error code refers to the dryer vent. This can refer to the dryer’s lint screen, the thermistor behind the filter, or the vent itself could be clogged.
In order to determine which one is the problem we will need to gather some information.
1. Will water pour through lint filter’s mess?
2. Outside where the unit vents on the side of the house can you feel air coming out?
3. Is the vent hose on the backside kinked or clogged?
4. Obstruction on vent housing outside (if screen is present on outside remove right away this is a fire hazard.)
Water should pour through the lint filter easily. Fabric sheets will put a layer of wax on the lint screen causing the dryer air circulation to be cut off. We should be able to feel warm, moist air at the vent outside. If air is not present you are in need of a dryer vent cleaning. A kinked or clogged vent hose can also cause the E01 error code. Ensure the vent hose is clear and placed in position with as few bends as necessary. When the vent is clear the E01 error should clear itself upon start up.
