Is there anyone having experience that you used 50hz filter in 60 hz
area?

I bought Eheim Pro3 2073 230V 50Hz in Germany and tried to operate in
220V 60Hz area.
Firstly it seemed to work well but after some minute, it made irregular
noise and didn't work well.
Do you guys have any experience and know any tip to resolve my problem?

About all you can do is get a new filter that uses local power. It
will just burn up otherwise.
