Sorry for the English, I am from Sweden, I understand German but is really bad in writing.
I have a Eheim 2078 who constantly run I calibration mode if I try to run it I high flow rates, at low rate it runs OK.
I have checked everything in the pipes and filter, can't find any problem.
Can a firmware upgrade solve this problem? I'm running 4.0 in the filter now. See attached print screens.
I have found the files in this sides download area but I need a password for the zip file.
Best regards
Peter
