karcher pressure washer wont work like normal?

pressure washer in costco image

Kobe get y

i have a karcher 2500psi gas power washer i bought from costco 5 years ago, it runs fine every summer. this spring i took it out and power washed half of my driveway, i turned it off to take a break, when i turned it back on and started power washing, it would only shoot a weak stream. not enough to even break the dirt away, almost like a garden hose. I changed spark plugs, filled gas , filled oil. it will power wash for about 2 seconds, then go back to garden hose stream. i take off the nozzle, put it back on, and i get another 2 seconds, i have to keep repeating. but its senseless to keep doing this .

what could be the problem?

i noticed whenever the pressure washer does work it will jerk, then will go to garden hose stream mode

any help? thanks

Answer
Sounds like you need to replace the check valves in the pump. Or the pressure relief valve could be sticking open from trash or corrosion. You could try and clean them out. Probably will need to rebuild the pump.

is this a good pressure washer?

Answer
No, electric is not the way to go. If you plan to start a business you muct invest in a gas washer. Try Sam's Club or Costco thay have great deals. Electric do not have enough psi to do all the jobs you will run across.
