Fluval FX6 Trapped Air.. HELP

[CCXGT]

Up until about 3 days ago, my FX6 would do its shutoff thing and spit out bubbles for a good 10 seconds.
Now it barely does anything.
If I manually unplug it and plug it back in, it will cough up a dozen or so micro-bubbles then start itself.

If I shake the canister I can hear a lot of sloshing around and it is very clear that there is trapped air.

Both the input and output hoses are taught with no loops or dips at all.

Help me someone!

What i do is let it suck some air and slowly put it back in water... U can listen when it fills up.
Try

Ok I'll have a go when I get in.

What I was planning is emptying the canister with that drainage valve then letting it fill itself up again, would this solve anything?

Nope, didn't work.
I can still hear a large amount of sloshing when I shake the canister..
It sounds like the top 2 inches is just a pocket of air..

Pushing all the way down in the tank to give it more preassure? And rotate

It's drawing water fine but the canister just isn't filling up fully..

How about turning it off for a few seconds then back on? Also try moving it and tilting it a little while it's running and while it's off, you want to move the air around till it comes up through either the in or out hoses.

If I turn it on and off a bunch it does spit some air.. but not much.
I don't want to go about damaging the plug or blow a fuse.

And believe me, I've shaken like my life depends on it..

Can you fill it up before you turn it on?

Yes, you can either fill it with 8l manually or let it fill itself with water from the tank.

Either way, it should completely fill itself on startup.

So this still isn't working properly...
I've run out of things to try

How long have you had it, Can you get a refund or exchange it?

I would try to contact fluval directly. Maybe they have someone who can troubleshoot over the phone.

The manual for the FX6 I have says that it will not function properly unless there is at least 2 gallons of water in it before you try to prime it.

Not sure if that is true, just what it says in the manual

I could definitely get a refund..
But I still think trying to fix it and finding out why it's doing this might help.

I took it apart for a clean last week, it did the startup procedure fine but since then it hasn't expelled any air.

I tried contacting Hagen via their website, the Contact Us tab on there leads to a blank page though...
