Power steering fluid overflow from reservoir while bleeding

[DraftySquash]

So today I decided to top my PS fluid and bleed air out of it because the level was below MIN. 

I jacked up the front of the car, filled new fluid up to just below the MAX line so I have a reference and started turning the wheel slowly to full lock each way. 
around turn 24, the fluid in the reservoir overflew! 
now when I check the levels, it’s just above the MAX line. 
 

I’m trying to understand how all of a sudden this system has more fluid. Is there some air bubble still stuck somewhere which is causing the level to be higher than when I started? I’m confused about how the level went up, not down 😂

 

Any help would be much appreciated. I’m still turning the wheel to full lock and continuing with the bleed, and it hasn’t happened again. Only happened twice at the start. 
 

Thank you in advance

Also, next step after this is to turn the car on and do the same with full lock on steering. The levels have stopped changing now

Good news. Turned the car on and the level immediately went just between MIN and MAX.

Yeah that sounds exactly like what a big air pocket does when leaving the system....radiator bleeding can be the same. I'd say you are right to go now

Bleed it again with the engine running.

Hahaa yeah one good win turned into a day of misery. 
 

#1: found some connector that was badly patched up and cracked since. Now trying to figure out what that connector actually is so I can get it fixed.  

#2: I think my power steering pump might be kaput? I was running the car and doing the steering lock, looked underneath and there was a decent amount of power steering fluid on the ground 😔 my reservoir still has the same level I added so I’m confused about it. But I can see it on the underside of the car too so it’s dripping down from somewhere. The main hose under the reservoir looks fine so could it be the pump?

the reservoir has fluid up to just below max now

 
Because of issue #1, it’s not going to get driven much now anyway. I’ve done a patch up just so I can connect the piece tomorrow. And then I’ve got to figure out what on earth that is and how it can be replaced.

 

Here I was, really looking forward to topping up PS fluid and taking the car for a drive. So depressing 🤦🏽‍♂️🤦🏽‍♂️ the only day I’ve had no issues was when I changed the battery 😂
