PW turns off! Help needed


Hello guys, its me again. So i finally got an appointment next week to do some fleet washing! Im happy and nervous at the same time. So today i turned my PW to wash my truck and make sure everything was ok with it. Everything was fine for the first 15 minutes and then the machine turned off, so i checked fuel, choke, fuel valve and everything was fine, so i restarted the machine and worked well for another 2 minutes and then it shut downagain, so i rstarted it again and worked for a minute or less and shut off again… i did that for 4 times and then i let it for my own good.

Has any of you had this problem before?, do you have any idea of what could it be?. I am taking it tommorrow to a mechanic cause i dont know much about fixing machines.

I searched for this problem in the forum and didnt find anything similar.

Thanks in advance


What engine?


Sorry, its a vanguard engine , its a 4000 psi 4gpm belt driven, with electric start.


I think its a 16hp


Original gas cap or have you changed it recently? Try running it with the gas cap off. Don’t let it slosh around onto the motor.


Its the original gas cap , the model is Graco Force 4043BD i dont know how good this machines are… what does slosh mean?


47 PM


I didn’t want the gas to run out of the tank while machine was running. It sounds like the vent on your gas cap is clogged. Newer caps have charcoal in them and get wet and won’t vent.


Is it due for an oil change?


Lol @jzbreeland old Watkins finally paid up :grin::wink::wink:


Yes, you caught me. Grabbed the wrong screenshot lol.


Has any of you had this problem before?

Yes, the vent in the gas tank cap was lost. Replace your gas tank cap.


Got the problem fixed!, there was dirty gasoline with mud in the carburator. Cleaned it andnow working perfect!. Thanks!
