Frequently Asked Questions

Why is my Gaggenau oven locked?

The oven locks steam modes when limescale buildup is critical. Run the descaling programme with official Gaggenau descaling tablets (order #17002490) to unlock.

Can I use any descaler in my Gaggenau oven?

No. Only use the specified Gaggenau descaling tablets (order number 17002490). Other descalers may not fully remove limescale and the lockout message will persist.
