We purchased the new washer tower and had the store set it up.   I have always trusted LG products. And I reviewed the product online for pros and cons. When it was delivered the person went to push it into place and sparks came out the back and a fire melted the plastics on the back. 
I have just received another wash tower and had it installed. Seems to be fine. I however am still a little nervous. The store was great in taking care of the unite and luckily there wasn’t any damage to my house ( little water on the floor from putting out the flames). I just think buyers should treat these appliances with respect.
