EHEIM compactON pump

[fishstix]

I have the following pump running on one of my tanks for a manifold
EHEIM compactON 2100 (555 GPH) Aquarium Pump - EHEIM.

The pump is really loud, I thought they were not very loud. I have taken it apart, it looks fine, but rattles really loud, also when I run it I have noticed my tank temp goes up. It only about 2 months old.

Any suggestions other than calling EHEIM?

Thanks

That sounds like a pump problem. I run a CompactON 300 in my small FW tank and it is dead silent. I also run a 3000 as a water pump in my remote RODI reservoir and it is also dead silent. And your tank temperature rise is a concern. I suspect a failed bush or bearing.

I would contact your retailer or Eheim.
