Hello my name isXXXXX will be assisting you with this problem today. Thanks for trusting us to help you with this appliance
The door does not have a lock, You should be able to open it without power, If it is not installed yet grab the top, hold it still then grab the latch and pull.
I have never come across a dish washer yet that has a lock on it.
I would like to earn your highest rating, If I provide you with a answer this just means with the symptoms you have supplied me I am letting you know from experience where the problem is, this does not mean however that we have finished, If you have any additional questions please reply.
If I have answered your questions to your satisfaction please feel free to come back at any time after rating me "Excellent service" for additional questions you may have at no further charge :)
Sometimes I will have to give bad news, Please try to find it in yourself to rate me for the service not the bad news.
