Where is the unloading valve on my Karcher HD 3600 DH pressure

Customer Question

Where is the unloading valve on my Karcher HD 3600 DH pressure washer? The washer does not develop any pressure and there does not seem to be any resistance to turning the pressure adjustment knob.

Hello,
First, do you have a pressure tip installed on the wand?
Just checking the basics.
Can I get an exact model and serial number for this unit so I can see what type of pump you have?
Here is a youtube video you can check out. It's not your pressure washer, but the advice applies.
