There’s nothing more frustrating than having a power washer that’s not working properly. And when the soap isn’t working, it can make cleaning even more difficult. If your PowerStroke pressure washer soap isn’t working, there are a few things you can check to troubleshoot the issue.

First, make sure that you’re using the correct type of soap for your pressure washer. Some soaps are designed for specific tasks, such as cleaning concrete or siding. If you’re using the wrong type of soap, it won’t suds up properly and won’t work as well.

Second, check the water pressure. If the water pressure is too low, the soap won’t be able to suds up properly. Make sure that your water pressure is at least 2000 PSI.

Finally, check the soap dispenser. If the dispenser is clogged, the soap won’t be able to flow out properly. Clean the dispenser with a brush or a toothpick to remove any clogs.

If you’ve checked all of these things and the soap still isn’t working, you may need to contact a professional for help.

Reasons Why Powerstroke Pressure Washer Soap Not Working

Reasons Why Powerstroke Pressure Washer Soap Not Working

Incorrect soap type


Powerstroke pressure washers are designed to use a specific type of soap, which is usually a detergent or surfactant. Using the wrong type of soap can cause the soap to not dissolve properly or to clog the spray nozzle.

Too much soap

Using too much soap can also cause the soap to not dissolve properly or to clog the spray nozzle. The manufacturer’s instructions will specify how much soap to use, so be sure to follow those directions.

Not enough water

If there is not enough water flowing through the pressure washer, the soap will not be able to dissolve properly and will not be able to create a sudsy lather. Make sure that the water pressure is high enough and that the water flow is sufficient.

Dirty spray nozzle

A dirty spray nozzle can also prevent the soap from dissolving properly. Be sure to clean the spray nozzle regularly to prevent this from happening.

Blocked detergent line

The detergent line can become blocked, which will prevent the soap from flowing to the spray nozzle. If you suspect that the detergent line is blocked, you can try to clear it by using a small wire or by running a vinegar solution through the line.

Faulty soap dispenser

If the soap dispenser is faulty, it may not be able to dispense the soap properly. If you suspect that the soap dispenser is faulty, you should contact the manufacturer for repairs or replacement.
