10.1. Failure code function
In the event of a failure, a failure code is displayed to stop the operation.
• If an “F 18,” “F 19,” “F 97,” “F 98,” “FE 7,” or “FE 8” code failure occurs for the first time, or if the failure occurs a second time, you
are taken back to the initial display screen. If the failure occurs a third time, the corresponding failure code is displayed.
• If an “F 98” or “FE 8” code failure occurs for the first time, you are taken back to the initial display screen. If the failure occurs a
second time, the corresponding failure code is displayed.
• Once displayed, the failure code “F 18,” “F 19,” “F 97,” “F 98,” “FE 7” or “FE 8 is stored in memory, which prevents the oven from
operating even if any part is replaced, and it remains displayed until the stored failure code is erased. Erase the stored failure
code before conducting an operation test.
• Even if displayed, the failure code “F 00,” “F 06,”cannot be stored.
