SOURCE: no pump pressure
Sounds like the diaphragm in the pump unit has failed, the engine and the pump are two seperate things the engine only operates the pump but if the diaphragm is leaking or broken you wont get any pressure

if the machine is running on suction, ie sucking out of a barrel there may be an air leak on the suction hose or pump. it will pull air easier than pulling water .
put the machine under mains water pressure, hose pipe straight from tap to pump.
check all around the pump and inlet pipes for leaks.
if water leaking this needs rectifiying for it to work on suction.
run the pressure washer while on mains pressure with the hose on, does this make a difference?
if not then probably the unloader is stuck in the pump head. remove unloader , clean and replace it
parts breakdowns are available on the internet for your machine.
possibly valves stuck, or the valve springs have broken, seen this quite few times on these machines. if so replace springs .
These sort of machines do not last very long anyway, about 50 hours use if your lucky.

check the water filter ---high pressurehose must have bbackpressure to develop pressure so disconecting it wont acheive ,much ,if you have agood water supply ,oil in the pump--- adjust pressure by srewing the brass fitting that the pressure hose attachesto, down that is clock wise a couple of turns or so and see if that makes a difference if not seals in the pumpmay be gone tha t should show by water in the oil

HI, It sounds like it is just stuck on the keyway as these can be very tight. You need to force the pump of evenly on either side and should come of if patient.

Testimonial: "I'm sure the answer is correct. Over time my use of harsh chemicals no doubt corroded the key-way."
