Exactly. Why don’t Bosch include the”Secret Flap” in the user care and maintenance instructions?
Looking back through this thread it appears to be a consistent feature on Bosch Condenser dryers dating back to 2010 at least.
Checked my manual to be sure and there is nothing about it?
I wonder...
This thread is excellent! Thankyou Guys
I’ve been vigilant about cleaning the filters/inner housing etc of my Bosch Condenser dryer since I bought it in 2016 (I don’t have time to a super-cleaner-I just want to keep appliances sound for as long as possible to save money & avoid waste & hassle)...
