Karcher Pressure Washer Leaking Water. Remove the case of the pressure washer and connect the water supply and hoses only (not the electricity). Replace any worn out or broken nozzles when they are discovered.
Sometimes water inlets break and begin dumping water inside the pump housing. Replace the garden hose that's attached to the pressure washer with a garden hose 3/4 inch in diameter or greater. Not sure if anyone has repaired a karcher electric k 3.98m before but its leaking from what i have been told is the water pump.
