Reasons Why Portland Pressure Washer Soap Dispenser Not Working

No Soap

The most common reason for a pressure washer soap dispenser not working is that there is no soap in the dispenser. Make sure that the soap tank is filled with soap and that the dispenser is turned on.

Clogged Hose

Another common cause of a pressure washer soap dispenser not working is a clogged hose. If the hose is clogged, the soap will not be able to flow through the hose and into the spray wand. To fix this problem, you will need to clean the hose.

Faulty Dispenser

In some cases, the soap dispenser itself may be faulty. If the dispenser is not working properly, you may need to replace it.

Incorrect Soap Type

Make sure that you are using the correct type of soap for your pressure washer. Some soaps are designed for use with cold water, while others are designed for use with hot water. If you are using the wrong type of soap, it may not dissolve properly and will not be able to flow through the hose and into the spray wand.

Low Pressure

If the pressure of your pressure washer is too low, the soap will not be able to flow through the hose and into the spray wand. To fix this problem, you will need to increase the pressure of your pressure washer.
