Why Sunjoe Pressure Washer Soap Dispenser Not Working

Nozzle Clogged

The most common reason for a SunJoe pressure washer soap dispenser not working is a clogged nozzle. This can happen if the soap becomes too thick or if there is debris in the nozzle. To fix this, you can try to clear the nozzle with a toothpick or needle. If that doesn’t work, you may need to replace the nozzle.

Low Pressure

If the pressure washer is not producing enough pressure, the soap may not be able to reach the nozzle. This can be caused by a number of things, such as a clogged filter, a faulty pump, or a problem with the water supply. To fix this, you will need to identify the cause of the low pressure and take steps to correct it.

Faulty Soap Dispenser

In some cases, the soap dispenser itself may be faulty. This could be due to a broken or worn-out pump, a faulty valve, or a problem with the electrical wiring. If you suspect that the soap dispenser is faulty, you will need to have it repaired or replaced.

Incorrect Soap Type

Not all soaps are compatible with pressure washers. Some soaps are too thick or viscous, and they can clog the nozzle or cause the pressure washer to malfunction. Make sure that you are using a soap that is specifically designed for use with pressure washers.

Incorrect Soap Concentration

The concentration of the soap can also affect the performance of the soap dispenser. If the soap is too concentrated, it can clog the nozzle. If the soap is too dilute, it may not be able to produce enough suds to clean effectively. Make sure that you are using the soap at the correct concentration.

How to Troubleshoot And Fix: sunjoe pressure washer soap dispenser not working

Symptoms of a sunjoe pressure washer soap dispenser not working

There are a few different symptoms that you may experience if your sunjoe pressure washer soap dispenser is not working properly. These include:

The soap dispenser does not dispense any soap when you press the trigger.
The soap dispenser leaks soap.
The soap dispenser makes a hissing sound when you press the trigger.
The soap dispenser is not aligned with the spray gun.

Troubleshooting a sunjoe pressure washer soap dispenser

If you are experiencing any of the symptoms listed above, there are a few things you can check to troubleshoot the problem.

1. Check the soap reservoir:

The first thing you should check is the soap reservoir. Make sure that it 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 reservoir is full, but the soap dispenser is not dispensing any soap, you may need to clean the soap dispenser.

2. Clean the soap dispenser:

To clean the soap dispenser, you will need to remove it from the pressure washer. Once the soap dispenser is removed, you can use a toothbrush or a small brush to clean out any debris that may be blocking the nozzle. Be sure to rinse the soap dispenser thoroughly with water before reinstalling it.

3. Check the soap hose:

The soap hose is the flexible hose that connects the soap dispenser to the pressure washer. If the soap hose is kinked or damaged, it can prevent the soap from flowing properly. To check the soap hose, inspect it for any kinks or damage. If you find any damage, you will need to replace the soap hose.

4. Check the soap pump:

The soap pump is the part of the pressure washer that actually pumps the soap out of the reservoir and into the spray gun. If the soap pump is not working properly, it can prevent the soap from being dispensed. To check the soap pump, you will need to remove the soap reservoir and the soap hose. Once the soap pump is exposed, you can use a multimeter to check for continuity. If there is no continuity, you will need to replace the soap pump.

5. Check the pressure washer’s settings:

The pressure washer’s settings can also affect the soap dispenser. Make sure that the pressure washer is set to the correct pressure for dispensing soap. If the pressure is too high, it can cause the soap to foam up and not dispense properly. If the pressure is too low, it can prevent the soap from being dispensed at all.

6. Contact sunjoe customer support:

If you have tried all of the troubleshooting steps above and your sunjoe pressure washer soap dispenser is still not working, you can contact sunjoe customer support for help.
