I have a 2.5 gpm model K2400HH pressure washer that won't sprey with high pressure, it started intermitanly, now won't spray high pressure at all. Last year I removed the valve and cleaned it and put white lithium greese on it and it worked pretty well for a while, but now no high pressure

I would suggest purchasing a new revised unloader valve, here is the link to purchase one
