I am having a terrible burned taste from my juices using the ce3. it has only been happening in the last pk of them I got which is only 2 weeks ago. It does not matter if I use my 650 batt or my 78mm batt. What is going on??? My juice is 30/70 but not thick. I have used ce3's for the last 2 months and the problem keeps getting worse which each new batch I get...Any thought or advice would be helpful.
