The oven compartment is dirty.
Clean the oven compartment after each use if possible. Allow the oven compartment to cool down fully before cleaning. Use a clean sponge and warm water with a little liquid dish soap or a clean, damp microfiber cloth.
Consult the operating instructions for further information.
For thorough and gentle cleaning of your oven, it is recommended to use Miele products which also care for your appliance at the same time.
