SOURCE: craftsman model 580.752020 electric pressure
turn off water and machine electrics.
remove high pressure hose from front of machine, this may be tight if there is still pressure in the system.
turn on water, when water comes out of machine hose outlet turn on machine. does the machine turn on and water flow increase, if so you probably have a blocked lance jet or trigger.
remove lance extension if fitted and fit hose back to machine, try again. If its ok then this proves you have a blocked lance jet, maybea poke about with some stiff wire will free the obstruction.
If this doesnt bring on the machine you probably have a jammed pressure switch on the pump.
this pressure switch turns on the pump when the trigger is pulled and switches the motor off when the trigger is released.
hope this helps.
SOURCE: Where can I get seal rings and o rings for my
MSC industrial www.mscdirect.com sells metric O-rings by the bag. If you measure what you've got, you can make an educated guess what to replace with.
SOURCE: Have a tradesman h120 pressure washer..it will not
If the pump was run without having the supply hose hooked up and water to the pump before turning it on, you have destroyed the seals and they need replacing.
