actually means.
Gaggenau combi-steam ovens remind you to descale based on water hardness and use. If the reminder is ignored and repeated, the oven locks its steam modes to protect itself and shows this message; modes without steam still work.

If the lock stays on after a full program with the right tablets, book a visit.
What not to do
This message is not a broken oven. It is a planned lock that lifts once the descaling program finishes.
