Why does my Siemens Coffee Maker display “Please open door, switch off with power switch and then back on after 30 sec!”?

If your Siemens Coffee Maker displays “Please open door, switch off with power switch and then back on after 30 sec!”, it could be because the appliance is too warm. Let the appliance cool down. Another reason might be a dirty brewing unit. Clean the brewing unit.
