You may be using too much or too little soap. The ideal soap concentration for a pressure washer is between 1 and 2%.

Dirty Soap Tank

If your soap tank is dirty, it can prevent the soap from being properly dispersed. Make sure to clean the soap tank regularly.

Clogged Nozzle

How to Troubleshoot and Fix: Soap Not Working on Sun Joe Pressure Washer

Problem: Soap Not Dispensing

If your Sun Joe pressure washer is not dispensing soap, there are a few things you can check to troubleshoot the problem.

1. Check the soap reservoir:
Make sure that the soap reservoir is filled with soap and that the lid is tightly closed. If the reservoir is empty, fill it with soap and try again. If the lid is not closed tightly, the soap may be leaking out of the reservoir and not reaching the nozzle.

2. Check the soap nozzle:
The soap nozzle is located on the end of the wand. It is a small, black nozzle with a hole in the center. Make sure that the nozzle is not clogged with soap or debris. If the nozzle is clogged, you can try to clean it with a toothpick or a needle.

3. Check the soap hose:
The soap hose is the hose that connects the soap reservoir to the nozzle. Make sure that the hose is not kinked or damaged. If the hose is kinked or damaged, you will need to replace it.

4. Check the soap pump:
The soap pump is located inside the pressure washer. It is a small, electric motor that pumps the soap from the reservoir to the nozzle. If the soap pump is not working properly, you will need to have it repaired or replaced.

5. Check the pressure washer settings:
Make sure that the pressure washer is set to the correct setting for using soap. If the pressure is too high, it can damage the soap nozzle. If the pressure is too low, the soap will not be able to reach the surface that you are cleaning.

6. Check the water supply:
Make sure that the water supply to the pressure washer is turned on and that the water pressure is sufficient. If the water supply is turned off or the water pressure is too low, the soap will not be able to be dispensed properly.

Troubleshooting Tips

If you are having trouble troubleshooting the problem, you can try turning the pressure washer off and then on again. This will reset the pressure washer and may fix the problem.
You can also try cleaning the soap reservoir and the soap hose with a degreaser. This will remove any soap residue that may be clogging the nozzle or the hose.
If you are still having trouble, you can contact the Sun Joe customer service department for assistance.

Solution: Soap Not Foaming

If your Sun Joe pressure washer is not foaming, there are a few things you can check to troubleshoot the problem.

1. Check the soap concentration:
The soap concentration is the amount of soap that is mixed with water. If the soap concentration is too low, the soap will not foam properly. If the soap concentration is too high, the soap will be too thick and will not be able to be dispensed properly.

2. Check the water temperature:
The water temperature can affect the foaming of the soap. If the water temperature is too cold, the soap will not foam properly. If the water temperature is too hot, the soap will be too thin and will not be able to be dispensed properly.

3. Check the pressure washer settings:
Make sure that the pressure washer is set to the correct setting for using soap. If the pressure is too high, it can damage the soap nozzle. If the pressure is too low, the soap will not be able to reach the surface that you are cleaning.

4. Check the soap nozzle:
The soap nozzle is located on the end of the wand. It is a small, black nozzle with a hole in the center. Make sure that the nozzle is not clogged with soap or debris. If the nozzle is clogged, you can try to clean it with a toothpick or a needle.

5. Check the soap pump:
The soap pump is located inside the pressure washer. It is a small, electric motor that pumps the soap from the reservoir to the nozzle. If the soap pump is not working properly, you will need to have it repaired or replaced.
