Will not siphon


This model pressure washer will only siphon from the soap dispenser when you have the low-pressure nozzle attached and then will only sort of dribble out the suds. Good for sudsing, but no good for cleaning. You'll have to suds 1st then change to a highwe pressure spray nozzle to perform the actual cleaning. If it won't siphon with the low pressure nozzle either, then check for a blockage (old, dried soap) in the suction line tubing. Hope this helps!!

Why won't It siphon soap?


Hello,
These units use a venturi to inject soap, where the tube goes onto the brass barb, that should unscrew and there is a little ball bearing and spring in there that sometimes stick when thay have not been used for a little while, if you clean the ball bearing up with some steel wool and lube it up and reassemble, 9 times out of 10 this will rectify your problem

Hope this helps,

Brad

John deere 3800psi pressure washer will not siphon detergent. the water end does fine but cannot get any soap


The only way the washer will draw soap into the line is with either the black tip installed or with no tip in wand at all.There is a ball and spring inside of the pipe that the siphon hose hooks to so when you use the washer with alot or even a little pressure the ball is forced up and blockes off the soap inlet port.So if you use it with no tip in the inlet port is open cause the ball isnt being forced up by back pressure.I hope this makes sense.

My soap will not come out of the hose. What do i


several things to check, soap only works with low pressure tip installed, are you using correct tip? second issue is on bottom of soap tanks some have a small valve , is it open? is the tube blocked with dry soap or contamination, flusk it with water to be sure.

Cannot get it to uptake the bleach for spraying Dewalt pressure washer 3100 psi


On most pressure washers you wont be able to draw soap/bleach into pump unless you are spraying on low pressure.There is a valve on the inside of inlet hose fitting that closes when high back pressure is sensed.Would it draw bleach into hose when wand tip is removed?
