Karcher G 3000 BH Engine Pumping Problem

I have a Karcher G 3000 BH pressure washer with the Honda GC190 6.0 HP engine. The engine starts and idols fine, but when using the pressure washer, the engine seems to surge. It will surge between working fine with high pressure to low idle and low pressure. Any ideas where to start?

This may not be a motor problem. It sounds like your pump is not working properly and the motor is just following the pump. First thing to do is check for leaks in the pump, wand hose, gun etc. It may also be a blown water seal inside the pump.

Honda GC190 engine shuts down on my Karcher 3000 PSI PW


Well would you believe that I have the very same problem. I suspected that the pump was seizing up, so we tried the pump on another unit and it worked fine. On inspection of the motor we found the cam (which also operates the decompression mechanism) was worn out. It's made of hard plastic. It is only about 7 dollars too, so cheap enough to fix. I have mine ordered now and feel pretty confident that that should fix it.

Engine keeps shutting down


Most Honda engines have an oil pressure switch that prevents engine damage due to low/no oil pressure. Make sure there is sufficient oil in the engine and that the wire is connected to the pressure switch.

Pressure surge on and off for 2 seconds w/ new Karcher


It can be one of three conditions,
  1. The water supply in is not sufficient
  2. The pump oil is low
  3. The seals are bad in the pump.
I would check the first one first as this is the most common problem.
The water supply hose should be a high volume hose of at least 1/2 inch but 5/8 inch or greater is best.
