Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today.
Your lid switch is the issue on this, when the switches go to wash will stop running and nothing will happen no water going in no spin no agitate no drain, you will need to replace this, here is a link to the part, http://www.repairclinic.com/PartDetail/Lid-Switch-Assembly/12001514/400492?modelNumber=LSG7806ABE , replace this and it will take care of your issue, thanks, Bryan
Okay the dryer is eating your clothes ? This means the felt seal is worn and is allowing clothes to slide between the drum in the back and that's the reason it is eating your clothes, this is a little more difficult to get to, the other thing is the dryer has front glides, if these glides are worn in the drum is tipping down in the front and allowing a space in the back that something you should address also, these there is a video to show you how to replace them but the video is for a separate dryer not a stackable, in order to replace these you would need to remove the whole front of the dryer in your case removing all the screws around the top of the dryer and the ones underneath holding the front panel, here is a link to all the parts if that helps, I think I gave you the link for all the diagrams but if not I will give you both. Here is a diagram link.
parts list thanks and great job I'm glad you got your washer working again, have a great day, thanks, Bryan
