Bosch Oven HBG6753S1A/35 (FD9705) – error E6400 a few mins into Pyrolytic cleaning.

[disco4now]

We have had this oven about 12 months and it is functioning well. Recently tried the Pyrolytic cleaning for the first time. The first time used Pyrolytic level 3. After a few minutes error E6400 appeared with message to press the On/Off.
Tried it again a bit later on Level 1 with the same result. Other than this is it is still working well.

Any clues to what the E6400 error code means.

Thanks

We have had it fixed under warranty. E6400 is about a ventilation flap not opening when the oven heats up. Was happening about 4 minutes into the cleaning cycle. You could hear the motor turning that opens the flap via a cam, but it just kept cycling as it did not stop with the cam in the correct spot to keep the flap open.
