Problems with resitance

[dgommers]

I have an elite direto XR for 2 years now. Since a week i'm having problems with the resistace in zwift. The resistance in de trainer goes up for no reason (flat and even going downhill) and i can't keep my cadance at 80-90 rpm. Even going downhill i have to shift in my lower gears till the moment i cann't peddle anymore. Multiple callibration in my-e-training app and zwift didn't solve the problem. How to solve this?
