Default Karcher Pressure Washer question?

On Fri, 17 Apr 2009 21:42:44 -0400, wrote:

I have one and use it regularly. However, it no longer will syphon in
any liquid through the dip hose. I've cleaned and tested the intake
filter so it flows easily and the tube is clear.

Can anyone advise if it is possible to repair this condition? If I
disassembled the unit to gain access to where the intake hose connects
to the pump, is there anything that I can do at that point?

Thanks in advance for any suggestions.


The pressure washer creates the vacuum by the venturi effect.
Basically a small orifice is placed in the path of flow to increase
the speed of the fluid within the orifice. A small soap inlet line is
then connected to the high speed fluid. This connection creates the
vacuum.

The small size of this soap connection may be plugged with debris.
Try to force a cleaning agent into the soap inlet or blow air into it.
