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.
plugged up, run a wire inside to unplug it.
Also, don't know how they all work, but mine will only suck up the liquid when the nozzle is set to wide open flow, lowest pressure.

I have no specific knowledge on your power washer but if forcing air through the line does not clear the passage then the passage may have a stubborn soap plug. Soap can dry and plug the small passage to the venturi. Try to force or let stand a soap dissolving chemical like Tilex soap scum remover into this line.
replying to bobm3, Mr.T wrote: I had the same issue. Total disassembly was needed to access the Venturi. Soap had hardened inside it. When cleaning out the brass fitting leading to it there was a small bearing with a spring behind. Be careful not to lose as I almost did. The hardened soap was difficult to get out, but using a paper clip should work. I also blew out the blockage with a can of air duster. I just hope that I put the bearing and spring back into the fitting in the correct order.
