Should I return this pressure washer?

I purchased this pressure washer a little over a week ago and although I've gauged my water flow rate to be over 4.5 GPM (this requires 2 GPM), I keep getting pulsing/variable action from the motor when using a high pressure setting on the spray wand even after trying all troubleshooting steps listed in the manual (see below). Should I be calling the return hotline ASAP?

A few more details: I bought this from the Home Depot Canada website but it was shipped ground from Arkansas to Vancouver and when I got the box, there was a gash in the side, but not in any area near the main body of the washer. As far as I could tell, it was a new item.

I've tried all the troubleshooting techniques (no kinks in hose, cleaning input filter, making sure air has been bled off from the system and there are no visible leaks) to no avail. I've tried a heavier-duty hose as well and another faucet. All my neighbours use similar residential style electric pressure washers and don't seem to have any issues. I'll likely try it on our shared complex's public faucet to see if it makes a difference.

I know this model has had complaints about the GFCI tripping easily, but that doesn't seem to be an issue as far as I can tell.

I have the 1650psi version, and the motor pulses/surges every 1.5 seconds or so, but the spray is constant. Does your spray pulse in time with the motor?

Yeah, the spray dies out when the motor 'stops' every half-second or so. I found this video of a working version of my model (the Karcher 2.38 1600 PSI) and it looks like it should be continuous.
