Hi I have a white knight 77aw-3 condenser dryer. Couple months ago it started to sound like a tank!! To the extreme that It's so loud I stopped using it with 2 doors closed. The bearings have been changed and it sounds to be coming from the motor. Any ideas please. I'm not very happy as I had 3 year guarantee and this happened a month after it ran out and white knight wouldn't help unless paid 126 pound. Thank you
