Your Kärcher K1900 may be producing half the pressure and making noise due to the pump sucking in air. This can happen if hoses or fittings are not airtight. To fix this, check all hoses and fittings for tight connections. Then turn off the machine and purge the pump by squeezing the trigger gun until a steady flow of water comes out of the nozzle.
