Code Description Explanation and Recommended Procedure
PF Power FailurePF indicates that a power failure occurred while the dryer was running. Press START to resume
the cycle, or press POWER to clear the display.
AF Restricted Air Flow Indicates low air flow that may affect dryer performance.
Confirm that airflow system is not blocked. Check lint screen, exhaust duct, exhaust fan.
• Refer to Fault/Error Code “F4E3”, page 7, for recommended procedure.
L2 Low Line Voltage L2 indicates low L2 voltage (less than 30 V) is detected at the CCU.
• Refer to Fault/Error Code “F4E4”, page 7, for recommended procedure.
