Seio 620 - Update/problem

[whaase]

Thanks, for all the replys. Makes sense now, but, my seio seemed to have died. I had it running for 3 days, I had to shut it off for a couple minuts. When I turned it back on, nothing happened. I took it out, cleaned it (how ditrty could it be?). When I plug it in, I hear it humming, I took it apart again, this time I very loosely screwed the outer ring back on and plugged it back in. I have to smack it then it started. I let it run in fresh water over night, unplugged it, plugged it back in and it won't start again.... anyone have any ideas?
