Not sure what that is. Does B-AP25-7 sound right?
Expert:  Daniel T. replied 1 year ago.
If you open the main oven door theres usually a rating plate on the oven frame and it will start E-nr.

Hi
Thanks for that ive got it now.
The fault you have is a communication fault between the main control board and the front display control board.
What you can try first if you havent already is turn the power supply off to the oven for 20 minutes as this will allow the electronics to discharge themselves. The after 20 minutes turn it back on and see if this has cleared the fault.
If not then you need to pull the oven out and remove the top panel and from there you will see the main board and the front board. Locate the wiring block connecting them both. Disconnect the wirng at both ends and give the block a gentle squees and refit it and see how it goes from there.
But if after all the above its still the same then im afraid you have a fault on one of the electronics there. As they are just control boards theres no way of testing them to see which is faulty so its a case of replacing it. Now most of the time its the main board that fails rather then the front display board.
But try the above first and see how it goes and let me know.
