Wolf CSO Steam Oven Code E54 / F7: relay board locked for safety

What E54 / F7 means

On Wolf CSO convection steam ovens, including the CSO30 series, E54 with F7 means errors E43 to E49 were acknowledged 10 times, and the relay board stays locked for safety. The oven shows the pair and refuses to run, because the earlier relay errors were never solved and the safety lock now holds the board.

! Why to stop there

The lock exists to protect the oven, so it should not be forced.
The earlier relay problem must be found and repaired.
We quote in writing first and cover the work for 30 days.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.
