Problem: It is difficult to open the appliance door

Reason: Did you open the door right after you closed it?

Solution: If you try to open the appliance door within one minute after you closed it, you may have difficulties because of the pressure inside the appliance. Try to open the appliance door again in a few minutes so that the internal pressure stabilizes
