Hi all. I have an Eheim 2026 that was working fine this morning. Its been a while since I did maintenance on the filter, so I decided to do that, plus change the gaskets. I put brand new gaskets in (on the tubes-2) and my main gasket is relatively new. I put some KY on the main seals and the priming unit since my prime button (or whatever you call it) was sluggish. I set it up and it started to fill, then stopped. There was a lot of gurgling in the tubes (releasing air) and it just stopped flat. I have taken the filter apart 10 times with no luck getting it to prime or fill with water. I also cleaned out the intakes and output and the little ball.
What am I missing here?
