Karcher power washer don't work

Power washer has no high pressure water come out of it. I've watched all the videos I can find on YouTube and I still haven't figured out what's wrong with it. I've looked at the valves. In fact I have 2 of these power washers that don't work that I have had a part and looked at the valves and I'm not seeing anything wrong with any of them. Do you have any idea what might be wrong with these two power washers are there any other video other than YouTube that you can recommend.

Answer this question I have this problem too

Is this a good question?
