Pressure washer doesn't always shoot full power when trigger pressed.?

pressure washer karcher manual image

We have a Karcher 2400psi, (5HP Honda engine) pressure washer. When we press the trigger it doesn't always shoot full power...the engine tends to try to rev over and over somewhat like it's idling. Sometimes it will shoot full pressure as soon as the trigger is pressed, other times it can take between 10 seconds and 1 minute to get it going. Once it does shoot water out at full pressure thought the engine will rev up at a higher steady speed which seems normal.

We have had this issue since day 1 and it's really starting to annoy us.
The pressure on the mains of our house is more than enough so we think it might be the valve on the trigger.

Any ideas on what's happening here?
Any suggestions on fixes?

Thanks

I think you need to refer to the owners instruction manual for causes and cures.

Problems With Karcher Power Washer?

EchoNovemb

I have a Karcher K2400 HH gas power washer that won't hold pressure. It will pressurize for a few seconds, then cut off. Any ideas on how to trouble shoot this? Any ideas on what may be the problem, and how difficult would it be to repair? Thanks

Answer
There is a pressure cutout switch that may need adj. But would go to the users manual and go through the troubleshooting section to find problem. If you have lost manual go to karcher.com then america then US then residential pressure washers then manuals and then find yours.
