Question about Karcher 5/16 INTERNAL L/W .332 ID X .620 OD ZINC

To determine if your problem is due to an easily replaceable part, follow these steps:
1. Connect the water supply hose, the pressure hose, and the wand WITHOUT any nozzle tip.
2. Turn on the water supply, and press the trigger until water is smoothly running out of the nozzle
after any air is all purged out. Release the nozzle trigger.
3. Start the engine, and let it warm up for about 30 seconds.
4. With the engine running smoothly, press the nozzle trigger. The water should flow out of the nozzle (without the tip installed) at a faster rate, while the engine noticeably loads down as it used to do before your "no pressure" problem. If it does not load down, turn it OFF, and disconnect everything, and contact a Karcher repair facility.
5. If the engine does load down, release the trigger, and install one of the nozzle tips (not the black one).
6. Press the trigger, and the engine should load down, and you should have normal pressure from the wand. After you release the trigger and press it again, you will probably again have no pressure, and the engine will not load down. Removing the nozzle tip, pressing & releasing the trigger, and re-installing the tip should give you normal pressure again, but releasing the trigger will cause no pressure until you again remove the tip, press the trigger, and re-install the tip.
This is caused by a bad UNLOADER VALVE, which is located under a black cap with a metal button on it located on the top front of the pump. I don't know if you can purchase the replaceable parts from a Karcher repair shop, but when a neighbor & I took his washer to a repair place, it looked pretty simple to do this repair, and he was charged about $60 to replace a $5 (maybe) part, and it took about 5 minutes.

Well, first the easy bit... the pulsation is caused by the leak, because the machine can't hold pressure when the trigger is released. The difficult bit is: what to do about it? Unfortunately, there are several different places where the leak can occur and, even with the cover off, it's usually impossible to be sure exactly where the water's coming from. In the repair shop where I work, we almost always replace every part that might be causing trouble without even trying to identify the exact source. To do otherwise will rack the labour costs up so high as to render the job uneconomic. We reckon that if you can't complete the job in 45 minutes it's not worth it. Sad really, but such are the realities of our economics.
Anyway, unless you are a really competent handy-person, this is probably a job you won't want to tackle for yourself. So your choice is either to live with it (and do whatever you can to limit the pulsating time - keep it working or switch it off immediately) or take it to a repair shop. If you are in the UK, Karcher head office can direct you to a repairer, and I guess the same applies in many other countries too.
If you do want to have a go at it yourself, post another message here and I'll give you as much guidance as I can (but there will be a limit to the amount of detail I can provide, as I can't get in to writing a complete service manual!).
