I have a Karcher 2400 pressure washer that I have been trying to remove the spill valve. I can push it in slightly but can't remove it. There is a bypass just above it which won't allow it to pop out when I run it. Have soaked for 24 hrs. Any ideas? Thanks...

Did you find hte part in the pictures I sent to you. Do they show enough detail to determine if the part is threaded? This may be a proprietary part, only availble from Karcher or another PW sold by the same group of companies.

Do you have a local Karcher dealer?

Your Karcher is different than either of my pressure washers, so I am not familiar with the unloader on your machine.

OK I had my doubts as to how much success I would have and I wasn't. WhenI first started the washer I did have full pressure. When I released the trigger and squeezed again there was no pressure. I found by lowering the throttle the pressure would come back. I went to full throttle (while squeezing) and there was pressure until I released the trigger. I will try to get the valve out after I purchase a pair of needle nose vise grips. I will also try to contact the repair company that you found with the info for repairs. I will be in touch.:thumbsup:

Here's what I ended up doing with my Karcher PW. I removed the piston guidance assembly and plugged the opening to the thermo valve which was allowing the water pressure to bypass the unloader valve. I reassembled the unit and started the motor with the trigger squeezed and had full pressure! When I released the trigger the pressure backup was,,,, to say the least awsome!! I squeezed and released a few times then left the trigger released hoping to blow out the unloader, which a tech with a company that sells and services these machines said was the way to do it sort of.:no: I was standing a distance from the PW and all that happened was the motor shutdown. I have givin up at trying to remove the unloader valve and ordered a new piston guidance assy.:mad:
