How to Start a Pressure Washer After Sitting: Easy Step-by-Step Guide

how to start pressure washer after sitting

So there it is, your trusty pressure washer, ready to be put to work after a long period of sitting idle. But as you go to start it up, you’re met with disappointment – it won’t turn on. Don’t panic just yet! This is a common issue that many pressure washer owners face, especially after the machine has been inactive for a while.

The good news is that with a few simple steps, you can get your pressure washer up and running again in no time. Imagine your pressure washer as a car that has been parked for too long. The engine needs a little extra TLC to get started again.

In a similar way, your pressure washer’s engine may require some priming and cleaning after being idle for an extended period. This is because gasoline can break down and clog the fuel system when left sitting for too long. So, how do you start a pressure washer after it has been sitting? First off, you’ll want to check the fuel level and make sure that there is enough fresh, clean gasoline in the tank.

Old gas can cause starting problems, so it’s important to replace it if necessary. Next, locate the fuel valve and ensure that it is turned on. This allows fuel to flow into the engine and helps with the starting process.

If your pressure washer has an electric start, ensure that the battery is charged and connected properly. Give it a quick check to make sure that there are no loose wires or connections. This step is crucial for electric start models, as a dead battery will prevent the engine from turning over.

Now, it’s time to prime the engine. Many pressure washers come with a built-in primer bulb that allows you to manually force fuel into the carburetor. This is particularly helpful after the machine has been sitting for a while, as it helps to push out any air bubbles that may have formed in the fuel lines.


If you’ve ever left your pressure washer sitting unused for a while, you know what a challenge it can be to start it up again. Luckily, there are a few simple steps you can take to get your pressure washer running smoothly once more. First, make sure you have fresh gasoline in your fuel tank.

Old, stale gas can cause starting issues. Next, check the oil level and add more if necessary. Then, turn on the water supply and squeeze the trigger to relieve any air pressure in the system.

Finally, pull the starter cord slowly until you feel resistance, then give it a quick, firm pull to start the engine. With these steps, you’ll have your pressure washer up and running in no time, ready to tackle any cleaning job that comes your way.

Preparing to Start the Pressure Washer

Starting a pressure washer after it has been sitting for a while may require a few extra steps to ensure its smooth operation. Before you begin, it’s essential to check the oil level and add more if needed. Next, inspect the fuel tank and make sure it’s filled with fresh gasoline.

Stale fuel can cause starting difficulties, so it’s best to drain any old fuel and replace it with a fresh supply. Once you’ve taken care of the fuel and oil, it’s time to prime the pressure washer.

Inspecting the pressure washer for any damage or issues

When getting ready to use a pressure washer, it’s important to inspect the machine for any damage or issues. This step ensures that it operates safely and effectively. Start by giving the entire machine a visual inspection, looking for any signs of wear or damage.

Check the hose to make sure it’s not cracked or leaking, and inspect the wand for any damage as well. Don’t forget to check the power cord and plug for any frayed wires or damage. If you notice any issues, it’s best to address them before starting the pressure washer.

By taking the time to inspect the machine beforehand, you can avoid any potential problems and ensure a smooth and successful cleaning experience.

Checking the fuel and oil levels

Just like with any machine that requires fuel and oil, it’s important to ensure that there is enough to properly operate the pressure washer. Imagine trying to start the pressure washer, only to find out that the fuel tank is empty or the oil reservoir is low.

It would be like trying to drive a car without any gas in the tank or oil in the engine. That’s why it’s essential to take a moment to check the fuel and oil levels before starting the pressure washer. By doing so, you can avoid any potential issues and ensure that your pressure washer operates smoothly and efficiently.

So, you’ve got yourself a pressure washer, but it’s been sitting around for a while and now you’re wondering how to get it started again. Well, don’t worry, I’ve got you covered! Starting a pressure washer after it has been sitting for a while may seem a bit daunting, but it’s actually quite simple. The first thing you’ll want to do is check the oil level and make sure it’s at the appropriate level.

Next, you’ll need to connect a hose to a water source and attach it to the pressure washer. It’s important to note that you should never start a pressure washer without having water running through it, as this can cause damage. Once you’ve done that, make sure the fuel tank is filled with fresh gas.

After these steps, simply turn on the fuel valve, choke the engine if necessary, and pull the starter rope to get the engine running. And just like that, you’re ready to start using your pressure washer again!

This process allows the pump to fill with water and prevents any damage that may occur due to air pockets. To prime the pump, you’ll need to connect a water source, such as a garden hose, to the pressure washer. Make sure the hose is tightly connected to avoid any leaks.

Next, turn on the water supply and let it flow through the hose and into the pump. This will fill the pump with water and help eliminate any air trapped inside. Once the pump is primed, you’re ready to start the pressure washer.

Tips and Troubleshooting

If you’re having trouble starting your pressure washer after it has been sitting for a while, there are a few steps you can take to get it up and running again. First, make sure the fuel tank is filled with fresh gas. Gasoline can go stale over time and can make it difficult to start the engine.

Next, check the spark plug to ensure it is in good condition and not fouled. If the spark plug is dirty or worn out, it may need to be cleaned or replaced. Additionally, check the oil level and make sure it is at the proper level.

Low oil can cause the engine to not start or run properly. Finally, if you have tried all these steps and are still having trouble starting your pressure washer, it may be a good idea to consult the owner’s manual or contact the manufacturer for further assistance. Remember, regular maintenance is key to keeping your pressure washer in good working condition.

One common problem that many people experience is difficulty starting the engine. This can be caused by a number of things such as a clogged fuel filter or a dirty spark plug.

To solve this issue, make sure to clean or replace the fuel filter and check the spark plug for any dirt or debris. Another common problem is low water pressure. If you notice that your pressure washer isn’t producing as much pressure as it should, start by checking the water supply.

Make sure the hose is not kinked or blocked and that the water is turned on to the highest setting. If the water supply is not the issue, then it could be a problem with the pump. In that case, you may need to clean or replace the pump to restore the proper water pressure.

Lastly, if your pressure washer is smoking or emitting a strange odor, it could be due to an oil leak. Check your oil levels and make sure that there is no visible leakage. If there is, you may need to repair or replace the oil seal.

By following these tips and troubleshooting steps, you’ll be able to start your pressure washer with ease and overcome any common problems that may arise.
