Recently I brought home fisher and paykel top load washer WA3927G1 from my brothers house in Brampton. It is only a year old and had not been used much. Recently I started to use it. It was working fine for at least 2 months and recently it started giving a little bit trouble. While the spin cycle the lid starts to pop up slightly and vibrate eventually. The lid is made of tempered glass according to the product manual. Before it gets worse, I wanted to know what would have gone wrong with it. It only happens during spin cycle.
