My Ryobi electric pressure washer seemed to be working all right yesterday, but today, when I try to start it, the engine just comes on for a moment or two, then stops. I've tried pressing the 'reset' button but nothing happens (and I'm not even sure how long you're supposed to hold it). I've tried plugging the pressure washer to different outlets to see if the problem was with t outlet, but to no avail. I'm a complete novice, so if this involves "resetting the house/shop breaker", I guess i'll need to find a site that will spell that out for me real clearly, but one thing at a time for now I suppose. Any help greatly appreciated.
