Operating noises
Noises that occur when closing a hot steam oven can be caused by the following:
Steam escaping from the appliance when the door is open
The walls of the oven compartment and the condensed water inside the appliance still being hot
Cold air getting into the oven compartment when the door is closed again
As the walls of the oven compartment are still very hot and the cold air heats up quickly, this air expands a great deal and very quickly
The air flows through the steam outlet opening underneath the control panel and into the kitchen
The eddies in the hose generated by the air flowing through it at high flow velocity create the noises that are heard
No remedy necessary.
