Sorry, Bosch don't recognise the E-Nr number.
I think you may have an 8 instead of the first B in BGB.
If you do, unplug the appliance.
Take the rear panel off to expose the thermostats.
Look for the one with the small button on it.
Firmly press the button till it clicks.
Reassemble and try the machine again.
Ensure the vent hose/vent ducts are clean and clear.
If all is ok, the machine should now be working again.
If still faulty, you are looking at a heater or control failure.
Hope this helps
