If you own a pressure washer, you know how important it is to keep it in good working condition. However, if you haven’t used your pressure washer in a while, you may run into some trouble when trying to start it up again. It’s common for pressure washers to develop problems after sitting idle for a period of time. In this article, we will guide you through the steps you need to take to successfully start your pressure washer after it has been sitting.

Step 1: Inspect the fuel system

The first thing you should do is inspect the fuel system. Check if the fuel tank has any old or stale fuel, as this can clog the system and prevent your pressure washer from starting. If you find old fuel, drain the tank and replace it with fresh gasoline. Additionally, check the fuel filter and clean or replace it if necessary.

Step 2: Check the oil level

Next, check the oil level in your pressure washer’s engine. Refer to the owner’s manual to find the oil fill cap and dipstick. Ensure that the oil level is within the recommended range. If the oil is low, add the appropriate type and amount of oil to bring it to the correct level. Remember to always use the oil recommended by the manufacturer.

Step 3: Prime the pump

After you have taken care of the fuel system and oil level, it’s time to prime the pump. Prime the pump by connecting a garden hose to the inlet of the pressure washer and turning on the water supply. Let the water flow for a few minutes to remove any air from the system. Once the water is flowing smoothly, turn off the water supply.

Step 4: Start the engine

Finally, it’s time to start the engine. Make sure the pressure washer is on a flat surface and the engine switch is in the “off” position. Pull the starter cord firmly and steadily to start the engine. Once the engine starts, let it run for a few minutes to warm up before using the pressure washer.

By following these steps, you should be able to start your pressure washer after it has been sitting without any issues. Remember to perform regular maintenance on your pressure washer to keep it running smoothly and extend its lifespan.

Why Pressure Washer Won’t Start After Sitting?

There are several reasons why a pressure washer may not start after sitting for a while. Here are some possible causes:

1. Stale Fuel:

One common reason is stale fuel. If the pressure washer has been unused for an extended period of time, the fuel in the tank can go bad. Stale fuel can clog the carburetor and prevent the engine from starting. It is essential to use fresh fuel or to properly store the pressure washer with a fuel stabilizer to avoid this issue.

2. Fuel System Issues:

Another potential reason is fuel system issues. Over time, fuel lines and filters can become clogged or damaged, preventing the proper flow of fuel to the engine. This can lead to starting problems. Regular maintenance, such as cleaning or replacing fuel filters as recommended by the manufacturer, can help prevent this issue.

3. Ignition Problems:

Ignition problems can also prevent a pressure washer from starting after sitting. Issues with the spark plug, ignition coil, or flywheel can disrupt the spark needed for combustion. Cleaning or replacing the spark plug and ensuring the ignition system is in good condition can help resolve this problem.

4. Oil Issues:

Inadequate or dirty oil can also cause starting problems. If the oil level is too low or the oil is contaminated, it can affect the engine’s ability to start and run smoothly. Checking and changing the oil as per the manufacturer’s recommendations can help prevent this issue.

Reasons for Pressure Washer to Sit

There can be several reasons why a pressure washer might sit idle for a period of time. These reasons include:

1. Lack of use: If a pressure washer is not used regularly, it can sit for long periods without being started. This can lead to problems such as stale fuel, clogged carburetors, and deteriorating seals.
2. Seasonal use: Pressure washers are often used seasonally, for tasks such as cleaning driveways or outdoor furniture. During the off-season, the pressure washer may sit unused for several months, requiring special care and maintenance before starting it up again.
3. Storage conditions: If a pressure washer is stored in a location with high humidity or extreme temperatures, it can be more prone to issues when it sits unused. Moisture can cause rust and corrosion, while extreme temperatures can affect fuel and oil viscosity.
4. Long-term storage: For pressure washers that need to be stored for an extended period, proper storage procedures must be followed. This includes draining the fuel tank and removing any residual water to prevent damage.
5. Improper maintenance: If a pressure washer is not properly maintained before being stored, it can develop issues while sitting idle. This can include failing to drain the fuel, not lubricating moving parts, or neglecting to clean and inspect the machine thoroughly.

Understanding the reasons for a pressure washer sitting idle can help you take the necessary precautions and perform the appropriate maintenance tasks to ensure that it starts up smoothly when you need it.

Steps to Prepare Your Pressure Washer

Starting a pressure washer that has been sitting for a while requires some preparation to ensure a smooth operation and avoid potential damage. Here are the steps you need to follow:

1. Inspect the Unit

Troubleshooting Tips for a Non-Starting Pressure Washer

If your pressure washer has been sitting for a while and is not starting, there are a few troubleshooting tips you can try before calling for professional help. These tips can help you identify and fix common issues that may prevent your pressure washer from starting.

1. Check the Fuel

Make sure your pressure washer has enough fuel in the tank. If the fuel level is low, fill it up with the appropriate type of fuel recommended by the manufacturer. It’s also a good idea to check for any signs of contamination or water in the fuel, as this can cause starting issues.

2. Check the Oil

Check the oil level in your pressure washer’s engine. If the oil level is low or dirty, it can prevent the engine from starting. Refer to the owner’s manual for the correct oil type and procedures for checking and changing the oil.

5. Check for Obstructions

Inspect the pressure washer’s intake and exhaust vents for any obstructions. Debris or dirt buildup can prevent proper airflow and cause starting issues. Clean any obstructions and ensure the vents are clear.

Questions and answers

What should I do if my pressure washer has been sitting unused for a long time?

If your pressure washer has been sitting unused for a long time, you should follow a few steps to get it started again. First, check the fuel level and add fresh gasoline if needed. Then, check the oil level and top it off if necessary. Next, check the spark plug and clean or replace it if needed. Finally, pull the starter cord or turn the key to start the engine.
