Karcher pressure fault or is it a normal thing?
OK so I set my washer up with the snow foam lance and pull the trigger, the washer kicks in and for a few seconds the foam is coming out thick and fast. Then for some reason the pressure washer seems to lose pressure or something and the foam quickly turns into water? The pressure washer isn't old and I've looked after it so I can't seem to figure out whats happening. If I release the trigger then press it again it seems to kick back in and I've got foam again. Am I doing something? Should I maybe use the washer for a bit before attaching the lance?
Just to add......
The washer works perfectly as a jet washer just seems to go mental when using the snow foam lance?
