BALLS!!!
Lovely. Just lovely. I was outside in the courtyard at work pressure washing several years worth of gunk off the flagstones and suddenly my pressure drops to nothing. I look behind me to see a geysering jet of water leaping from the middle of the hose. It appears that as I was moving around and using the wand, the pressure building and decreasing caused the hose to curl. It didn't kink, just curled upward. It also appears that it landed on the motor which was as hot as a the sun, and melted through the outer casing, insulation and inner casing of the hose. Damnit all to hell. In all the millions of safety warnings in the maintenance manual, of which I read cover to cover, it never once mentions that this could happen. This thing was brand spanking new too. Luckily it's one of the cheapest parts to replace, I think. Grrr....
