How to Dispense Soap From a Pressure Washer: Quick Guide
Assuming you have a pressure washer with an operational soap dispenser, there are only a few steps standing between you and sudsy success. Here’s a quick guide on how to dispense soap from a pressure washer:
- Fill the pressure washer detergent tank with your desired cleaning solution – just make sure it’s compatible with your model
- Select the appropriate nozzle for applying soap. You can find this listed in your user manual
- Attach the hose from the pressure washer detergent tank to the unit. Again, consult your user manual if you’re unsure how to do this
- Turn on your pressure washer and select a low setting. This is important because using too much pressure can actually cause liquid to be forced back into the tank
- Pull the trigger on the pressure washer wand to allow the solution to flow. You should see suds immediately
- Apply the soap to your surface using an up and down or side to side motion
- Once you’re done, turn off your pressure washer and release any remaining pressure in the hose. This will help prevent detergent from leaking out later
- Finally, disconnect the hose from both the pressure washer and detergent tank. It’s always a good idea to give everything a quick rinse with water before storing it away.
There are additional steps in this process – many of which come before actually setting up your unit. We encourage you to read our article on the best soaps for pressure washing – along with our discussion on how much soap to put in your pressure washer.

My Pressure washer Soap Dispenser Doesn’t Work…Now What?
Assuming you’ve followed all the advice above and your pressure washer soap dispenser doesn’t work still, now what? Even the best industrial pressure washer can experience issues here and there. And while you can certainly continue using the unit without soap in the meantime, you want to get the most out of your pressure washer. Eventually, you’ll need to address the issue and come up with a fix.
If you’re wondering why won’t my pressure washer dispense soap, keep reading. We’ll provide a few potential causes – and their accompanying fixes.
Why Won’t My Pressure Washer Dispense Soap? 5 Common Causes & Solutions
Sometimes, the cause for your pressure washer soap dispenser not working is as simple as a clog in the nozzle – or, perhaps you chose the wrong nozzle altogether. Or, it could be something more complex and convoluted – like a broken soap injection system. We’ll cover all this and more below.
You Have a Clogged Nozzle or Hose
Over time, it’s not uncommon for a nozzle or hose to become clogged with dirt and debris. This can be easily remedied by taking a quick look at the screen – if it’s caked with crud, simply remove it and give it (and the area around it) a good cleaning.
You may also want to check the pressure washer pump inlet screens and filters while you’re at it. Eventually, you may need to replace the nozzle and hoses altogether. We always recommend running pure water through your lines and out the nozzle prior to breaking the unit down to prevent this issue from arising in the first place.
The Detergent Tank Has a Clog
If you don’t have a clog in your nozzle or your hoses, the next step should be to check your detergent tank. If you made the mistake of leaving soap in your detergent tank and failed to rinse it thoroughly after the previous use, it’s likely that soap scum has dried and clogged the exit point in the tank.
The fix is simple – scrub it clean and remove the clog. And next time, clean your tank prior to unit breakdown!
You Chose the Wrong Nozzle for Soap
Another common reason your pressure washer soap dispenser doesn’t work is that you’re using the incorrect nozzle. Remember, different nozzles serve different purposes – some are designed for applying soap while others aren’t.
We have an in-depth resource on choosing the right soap nozzle for a pressure washer. There, you’ll learn that we typically recommend going with the black nozzle for soap – it has a larger orifice that decreases the water velocity. And thus, it increases the pressure in the hose, creating a better spray with soap.
If you still feel uncertain about which nozzle you should choose, check your user manual or contact Hotsy customer service for assistance.
The Detergent You Chose is Not Compatible
It’s also possible that the pressure washer soap you’re using simply isn’t compatible with your unit. This is why we always recommend checking with Hotsy (or another trusted source) before adding any new solution to your pressure washer. Using an incompatible product could cause serious damage to your machine.
If the detergent is too thick, it won’t be able to adequately make its way from the tank, through the soap injection system, and out the spray nozzle. This can be the result of either improper dilution or improper soap selection altogether.
Fortunately, we’ve written a complete guide on what kind of soap to use for pressure washing. Not only will this help you understand the importance of using only certified Hotsy soaps – but it will also help you pick the right formulation for any sort of job. Whatever you do, avoid going with a homemade pressure washer detergent! Shop at Hotsy for the premier selection of pressure washer degreaser soap.
Broken Soap Injection System in Your Unit
The soap injection system is responsible for mixing your detergent and adding it into the high-pressure washer that shoots out your nozzle. There are a few components in this system, and if any of them fail, it could prevent the unit from dispensing soap altogether.
If your pressure washer has a broken soap injection system, it likely needs professional repair. We don’t recommend attempting to fix this on your own as you could end up causing more harm than good. Contact Hotsy customer service or bring your unit into a local servicing location for assistance.
