I have a a white waring juice extractor. I have had it for 6 years now. I have noticed recently that on using it and feeding it with soft fruit such as oranges and grapefruits and tomatoes it needs to be pushed in the feeder quite hard for it to juice. When this happens it starts to make more noise and if more is fed, including harder vegetables it starts to vibrate and on many occasions starts to move around quite a lot. It is like it has a life of its own
I am wondering whether it the blade or whether it it badly balanced. In the past i have not had this problem. I hope you can help.
