How to Troubleshoot: DeWalt Pressure Washer Soap Not Working

Your DeWalt pressure washer is a powerful tool that can help you clean your home, car, and other outdoor surfaces. However, if your soap isn’t working properly, it can be frustrating and time-consuming to clean. Here are some tips on how to troubleshoot a DeWalt pressure washer that’s not dispensing soap.

Step 1: Check the soap tank

The first thing you should do is check the soap tank to make sure that it’s full. If the tank is empty, fill it up with soap and try again. If the tank is full, but the soap still isn’t dispensing, move on to the next step.

Step 2: Check the soap nozzle

The soap nozzle is located on the end of the wand. It’s a small, round nozzle that’s usually made of plastic. To check the soap nozzle, unscrew it from the wand and look inside. If the nozzle is clogged, you can try cleaning it with a toothpick or a small brush. If the nozzle is damaged, you’ll need to replace it.

Step 3: Check the soap hose

The soap hose is the flexible hose that connects the soap tank to the wand. To check the soap hose, inspect it for cracks or leaks. If you find any damage, you’ll need to replace the hose.

Step 4: Check the pressure washer pump

The pressure washer pump is the heart of the machine. It’s responsible for generating the pressure that sprays the water and soap. To check the pump, turn on the pressure washer and listen for any unusual noises. If you hear a whining or grinding noise, it could be a sign that the pump is damaged. You’ll need to take the pressure washer to a qualified repair technician to have the pump inspected and repaired.

Step 5: Reset the pressure washer

If you’ve checked all of the above and the soap still isn’t working, you can try resetting the pressure washer. To do this, turn off the pressure washer and unplug it from the power outlet. Wait a few minutes, then plug the pressure washer back in and turn it on.


These are the most common reasons why a DeWalt pressure washer’s soap might not be working. By following these steps, you can troubleshoot the problem and get your pressure washer back up and running in no time.

Additional tips

Use the right type of soap for your pressure washer. Not all soaps are created equal. Some soaps are designed for use with pressure washers, while others are not. Make sure to use a soap that’s specifically designed for pressure washers.

Dilute the soap according to the manufacturer’s instructions. If you use too much soap, it can clog the soap nozzle and prevent the soap from dispensing properly.

Clean the soap tank regularly. Over time, the soap tank can become clogged with dirt and debris. This can prevent the soap from dispensing properly. To clean the soap tank, remove it from the pressure washer and rinse it out with warm water.

Inspect the pressure washer regularly. Look for cracks, leaks, and other damage. If you find any damage, you’ll need to repair or replace the pressure washer before using it again.
