pressure washer runs for about 10 seconds then stalls, the pull string was rock hard afterward?




Brett


Trying to start this pressure washer (water hose was hooked up and everything), got it to start and it ran for about 10 seconds before it just stopped, sounded like the line was pushing water and getting stuck somewhere cause when I went to restart it the pull start was hard as a rock and when I finally pulled it something blew and water was coming out the bottom around the outlet tube, I had everything hooked up right I just wanna know if there is something else that would cause this
oh actually no water at all was coming out the end of the wand even if I pressed the trigger down



Answer
This is typically caused by a build up of pressure in the pump. Depending
on the pump on the washer, that build can be caused by a bad unloader or
even a stuck check valve. Please do not run the unit without the water
running, doing this can cause the internal parts of the pump to overheat
and possible become damaged. I would recommend contacting the manufacturer
of the pressure washer for a parts break down on the pump. Typically the
unloader and the check valves are simple to replace.

Why wouldn't a pressure washer be putting out any pressure?

I've had this pressure washer for 2 years, I just sold it and the guy says 'the pump cut out and won't come back on'. Its a 13hp Honda engine, on a 3600 psi 4gpm pump. What would cause a loss of pressure? If the pump seized, would the engine still run?
Its hooked up to a house spiket, I think it flows 6-8 gpm.



Answer
You didnt give much information as to what brand pump is mounted to the honda engine. But to venture an educated guess I would say Cam is right. The unloader valve is stuck in the unload mode. It could also be the "Easy-Start Spring" has broken and is locked in the start mode. (low pressure mode for easy starting of large horse power engines)
