After a long and painful experience with LG, I gave up and called Arni.
Right from the phone call, I've got an exceptional service.
Evgeni came to fix my washer and stack dryer on top of it, he even went extra mile and checked my dryer as well.
All was solved in under two hours.
My washer and dryer works like new now.
It is very rare nowadays to get service like that.
I highly recommend Arni.
