We have a Karcher G2500VH pressure washer. If you start the engine with the trigger pulled on the spray wand it will run at full pressure until you release the trigger. after that, when you pull the trigger it will not have any more pressure than the water hose feeding it. Does it have an internal unloader valve? What is the part number?

I have a Husky pressure washer with a Honda 2600psi engine. Problem is, no water will come from the pressure hose. I connected the water w/out the pressure hose and water flows thru strongly.

I have the Karcher 2400 psi, 5.0 Honda engine. Starts fine, but when you pull the handle on the spray wand, the pump does not kick in and the water just continues to trickle out of the end of the wand at regular faucet pressure. Occasionally the "clutch" will kick in and you have full pressure, but if it does and I let off of the trigger then chances are that it won't kick in again. has been getting worse for several years.
