Troubleshooting a Generac Pressure Washer Soap Not Working

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 dispenser

The first thing you should check is the soap dispenser itself. Make sure that it is properly attached to the pressure washer and that the hose is not kinked or blocked. You should also check the soap reservoir to make sure that it is full of soap.

2. Check the soap pump

If the soap dispenser is properly attached and the reservoir is full of soap, the next thing you should check is the soap pump. The soap pump is responsible for pumping the soap from the reservoir through the hose and out of the wand. To check the soap pump, you will need to remove the soap dispenser from the pressure washer. Once the dispenser is removed, you should be able to see the soap pump. If the pump is not working properly, you may need to replace it.

3. Check the soap hose

The soap hose is the hose that connects the soap dispenser to the pressure washer wand. If the soap hose is kinked or blocked, it can prevent the soap from flowing properly. To check the soap hose, you will need to disconnect it from the dispenser and the wand. Once the hose is disconnected, you should be able to see if there are any kinks or blockages. If there are, you will need to straighten out the kinks or remove the blockages.

4. Check the pressure washer wand

The pressure washer wand is the part of the pressure washer that you use to spray the soap. If the wand is not working properly, it can prevent the soap from being sprayed out of the pressure washer. To check the wand, you will need to remove it from the pressure washer. Once the wand is removed, you should be able to see if there are any blockages in the nozzle. If there are, you will need to clean the nozzle.

5. Check the pressure washer settings

The pressure washer settings can also affect the way that the soap works. Make sure that the pressure washer is set to the correct setting for using soap. If the pressure is too high, it can cause the soap to foam up too much. If the pressure is too low, it can prevent the soap from spraying out of the wand properly.
