Hose inlet popped out

I got the 1600 psi Ryobi powerwasher…  one day, when I was using it, the entire hose inlet part of the machine popped out the body .

I tried pushing it back in… as soon as I put water through the hose, it pops out again.

I want to fix it myself and save myself a hassle, but dont want to void warranty if my repair doesnt work out.

Anybody know anything about this?

Is it common?  Is it a simple problem or does it imply structural damage somewhere?

Thanks.

If it’s still covered under warranty, I’d contact Ryobi.  I have a smaller Ryobi power washer I grabbed on clearance a couple of years ago and need to see if it’s held up to my abuse.  It’s been sitting outside covered by a trash bag for the past few months, including a few deep freezes and a lot of bad weather…
