My Devilbiss WGV1721 pressure washer was working fine for about an hour and I shut it off for about 3 hrs and when I came back and turned it on and the pump was making a grinding sound and bogged the engine when being used to pressure wash so I immediately shut it off. There was some smoke coming out of a hole over top of the switch. What's wrong? is pump shot?
