Error code List
If there are any malfunction on each Sensors, each Motors, and power source and data communication lines in the operations, the
following displays blink and the all the operations stop.
Use them for the reference in the repair.
*1 You need to operate the Secret mode to remove the errors of F04 to F06, and F08.
(Users cannot remove the errors.)
However, you can move up and down the Ottoman/Reclining lift units.
Error code Malfunction Possible reasons Notes
