How to solve the problem of low pressure?

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.

I have the same problem. With mine I have to remove the tip that I am using then pull the trigger and then replace the tip and pull and pressure should return. I believe that one of my valves is sticking causing me to reprime the pump frequently. I am trying to clean or replace my valves to fix the problem.
I hope this helps.

This may not be a motor problem. It sounds like your pump is not working properly and the motor is just following the pump. First thing to do is check for leaks in the pump, wand hose, gun etc. It may also be a blown water seal inside the pump.

The most typical reason for this is that your supply pressure or volume is not sufficient. Try using a larger diameter hose.
