Is there a leak from the bottom ?
If so Problem, the leak is from the seam of the Manifold housing. There is a small crack in the seam. A design weakness.. A New Manifold Complete Replacement approx. $61.03.
If not you may replace the Pump Manifold Housing from Karcher, or locate a local Karcher Service Center.
If under 1 year old, and you can find a receipt,Karcher will replace the entire Pressure Washer under warranty.

I have no pressure and the pump surges when i release the trigger on my electric karcher modle k 2.360


If you have a Karcher then you should always post your machines barcode.

Because you have the low pressure and pulse this will be the valve block. Your machine has 3 piston and each has 2 valves (inlet and outlet). Because you dont have the barcode, i cant be sure if you will buy a valve kit of 6 valves or a pre-assembled manifold block.

it could be this machine and spares :

The karcher barcode is on a silver sticker and is usually 15 digits long. Example 156987400000123 is actually model 1.569-874.0 and serial number 00123....

To me this problem sounds like there is something wrong with the pump.
I think its better to buy another Karcher machine and get the 12 month warranty. As with old pressure washers you could spend money on certain parts to fix the machine but a few weeks/months down the line a different part of the machine could break and then you end up having to buy a new machine anyway.

Also being 15 years old you would have to check to see if parts are still made for the machine. This is because once Karcher discontinues a machine parts for that machine are manufactured for 10 years from that discontinue date.

I have a Karcher KB5050 it started to pulse when the trigger stopped


Is there water leaking from the bottom ? If so, then you have a leak in the pump. Bad seal or crack in the Pump.
If under 1 year old and have a receipt, Call Karcher for a warranty replacement.

Loss of preasue and pulses in standby mode


Check the oil. This is what happens when it is low on oil with my pressure washer. Kind of a safety feature.
