Meaning of the error:
The control has recognized an error in the inlet via the heat exchanger. The DC outlet valve (blue plug) may not open or its electrical values are incorrect (setpoint approx. 7.5kOhm). But ATTENTION: The outlet valve was available in different versions! Older models (up to the end of 2015) had an AC outlet valve (pink plug) and the setpoint here is around 2.2kOhm. It may be that the heat exchanger is defective or the lower valve is defective. That has to be professionally measured and checked once. It's not very easy. It can also be that the valve just got stuck or the plug does not get any contact. Here is a video guide for you as an overview. https://youtu.be/QE8isqZ6KUQ
