Thank you for submitting a question to Manage My Life. I know how frustrating it can be when appliances do not function properly.
According to the Owners' manual this washer and dryer should stack. You will need to purchase the stacking kit (part number 8541503). Here is a link that you may use to purchase this
. This kit comes with instructions.
I hope this is helpful. If I may be of further assistance as more details become available, please reply to this post.
If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
