I can't find my manual, and there is an F6 fault. I think it is due to the filter outlet. I took off the lower panel, unscrewed the white gismo on the lower right, pulled out several pieces of plastic and junk (I've done this before) and after several tries to get it put back without leaking, got it reinserted, and now even when I clear the display, restart the machine, after about 2 seconds of filling, it stops and the F6 signal comes back. Help!
