You need to perform this procedure to get rid of that code:

B. Procedure
1. Turn OFF the main power switch.
2. Turn main power switch ON while pressing the Utility/Counter key.
3. Touch [Trouble Reset].
4. Check to make sure that [OK] is displayed and the it has been reset.
5. After turning off the main power switch, turn it on again more than 10 seconds after and
check if the machine starts correctly.

By resetting it disappears. But after couple of jobs it appears again
