tunze osmolator warranty? help plz

[sharuq1]

Does tunze stand behind their warranty? I have an osmolator that the sensors seem to have been going on and today the thing overfilled my sump and I found water on my floor. I tried to call them but the number is from Germany and the line gave me a busy signal. I emailed their general info. address but I am worried they will give me the run around as so many companies do when it comes to a warranty replacement.

Has anyone ever replaced anything through the warranty? If so how did you go about doing it?
