Ryobi 1800W 2000PSI Pressure Washer not purging air

[JezFletcher]

Purchased this washer from Bunnings yesterday. Following the setup instructions, I've been running water through it without turning on the pump, in order to purge air in the hose or the unit. However, no matter how long I run, the flow still seems to sputter:

and in the inlet for the hose into the unit (which is transparent), I can still see air bubbles running through, which I assume shouldn't be there.

I've disconnected and reconnected all the connections multiple times, and I've tried two different garden hoses for input, and two different taps, and I still get the same result. I've not wanted to try turning on the pump yet, because the instructions are quite clear that the hose has to flow constantly before it's safe to do so. So I'm afraid of breaking a brand new washer by doing that.

We've previously used a (borrowed) Karcher pressure washer here with no problems. Any tips would be appreciated.
