What Is A Pressure Washer Soap Dispenser and How Does it Work?

The other nozzles spray water, but there is always one whose sole function is to spray soap and mix it with the water for one efficient spray. That nozzle is the soap dispenser. It might draw the soap from the detergent tank that comes with the pressure washer.

The soap dispenser works by mixing soap with water as you spray. It is typical to spray soap on any surface first before continually spraying water to tidy it up.

That’s why if anything happens to the soap dispenser, it is an alarming development because it means compromising the cleaning efficiency. That is why you need to know how to fix it.

Before we get to fixing the issue with your pressure washer soap injector, let’s see the leading causes of the problem.

Why Is your Pressure Washer Soap Dispenser Not Working?


Have you considered that you could be using the wrong nozzle? A pressure washer typically has about 2 to 5 nozzles depending on the type. You might be using the wrong nozzle and thinking that it’s the soap dispenser with an issue.

The soap dispenser can fail to work because of all the dirt clogging it up. As with any nozzle, dirt in the water will block it with time. As a result, the soap nozzle might fail to pass the soap you need to clean more efficiently.

If you’re using an overly thick soap or detergent, then the soap dispenser might have issues dispensing it. The wrong water to soap ratio might cause the resulting soap solution to have problems leaving the dispenser whenever you press for the soap.

Your pressure washer’s detergent dispenser might also fail to work because of an issue with the siphon tube. The siphon tube sucks the soap from the detergent tank. If it has any problem, then it will fail in its job rendering the soap dispenser useless.

The detergent tank might also cause your soap dispenser not to work efficiently. If you don’t clean it well after one use, it might have issues passing the detergent next time.

Your soap dispenser might also be having problems because the soap injector kit isn’t working well. The soap injector kit has several components that facilitate it’s working. Thus, if any of the features have issues, the dispenser won’t work.


So how do you troubleshoot this issue?


Step 1

Firstly, check to ensure you are using the right nozzle. You might be using the wrong nozzle and mistakenly thinking that your soap dispenser isn’t working. It might be working, but you aren’t using it.

Step 2

Clean the soap dispenser’s bore for any dirt. Water has minute dirt particles that, over time, might clog the disperser’s bore. Your solution to the dispenser not working might be to clean out the bore for any dirt that might be blocking it.

If it still doesn’t work after cleaning, you should consider replacing the old nozzle with a new one.

Step 3

Check the detergent to water ratio. If you mix the detergent with a smaller water ratio, it might be too thick to pass through the soap dispenser. Always ensure you mix the detergent and water in a balanced ratio.

Step 4

Check the siphon tube. Is it the recommended tube for the pressure washer you are using? Does it have any blockages? If it is the right one for your washer, check for any blockages and get rid of them.

Remember to use pure water to clean out any dirt or debris in the siphon tube.

Step 5

Check the detergent tank for any dried-up soap. If there is any, clean it out. Also, replace any stale soap with newer soap that is more viscous and flows smoothly.

Step 6

Remove the soap injector kit and inspect its components for any issues. It is usually near the washer’s pump. If you can’t see it, then refer to the diagram that came with your user manual.

Tow adjustable wrenches should help you take it apart and inspect for any damage. Use one of the wrenches to hold the power washer and the other one to hold the injector kit.

You then perform a 180-degree anticlockwise turn to loosen up the kit. After loosening it, you can easily remove it and inspect it for any damages. If it is okay, remember to lubricate it before returning it to its initial position.

If all the above steps don’t work, take your pressure washer to an expert for help.
