Last time I used this thing it worked but then my water supply ran out and I didn't realize it for a few minutes before I turned the washer off. Now, it runs but doesn't seem to generate any pressure. With the power off, if you squeeze the trigger you get the regular stream. When you turn the power on, the stream will get "misty" while the pump is cycled on but has no additional force to it. With the cover off I don't see anything that draws attention. It's a Campbell Hausfeld PW167600AV.
Here's a pic: 
Is there something I should try? Are the brass bolts or chrome set screws something I could tweak/adjust for diagnostic purposes? Should I just tear it apart and look for bad seals or broken parts or is there an easier way to go about this? |

Pump might very well be screwed. Letting pump run with no water flowing through it can be very bad for the internals. Lots of big angry warnings in the manual of my washer to not let it run when dry. Unless it's an oil cooled pump. Had a water cooled pump fail on my pressure washer. Replaced it with an oil cooled one. |

Most pumps are cooled by the water as it flows through the pump - if you had been using it for awhile ( got pump good and hot ) and then your water supply dried up for any reason ...it is very likely that you overheated and "burned" your pump up.
It is a pretty simple fix to replace the pump , but before you order a new one , make sure you can separate it from the engine. Then measure your shaft on your engine and pay attention to how it is secured ( bolt and/or key way ) then jump online and buy a CAT pump |

pump is done for. You can try replacing this part and that part, but pumps without water for even a limited amount of time will burn up. Think car with nothing in the radiator. Yup. Pressure pumps all have oil inside, and they still need a water supply whenever they are run. NEVER start the gas engine before you verify that you have water running through the pressure pump. Replace the pressure pump - it's an easy swap. Start here for the replacement pump: http://www.pressurewashersdirect.com/power/pressure-washer-pumps.html |
