Low pressure on Kärcher K4 Compact Pressure Washer

1 month 5 days ago - 1 month 5 days ago #3240 by newage

Hello!
My Kärcher K4 Compact Pressure Washer is pulsing like this:


The output pressure is low. There are no visible leaks.

I replaced the pistons seals, then the head . Nothing changed.
I am puzzled. Please, advice. What could cause the problem?


Another question:
Where and how does this

go?
Is it like this

or like this
.

Where does the spring go?
