Tubes are clear. I think that it must be the impeller. I'll get it checked out at the store from where it was purchased. Thanks to all who offered advice.

Shut off valves definitely open. Have checked input/output tubes and no blockages but I will double-check and advise.

The impeller does as you have described. All slime etc has been removed from the outside of the impeller and from the socket.

Thanks for the reply. I have inspected the impeller and I can report that it turns freely between incremental "stop points" which it can be easily moved past. Are these "stop points" normal?

After 12 months of perfect running and despite regular cleaning my eheim 2215 has started to pump very poorly. I have pulled it apart and cleaned it from "top-to-toe" and there has been no change. I have even run it without the media. There is no problem with the priming. Any ideas?
