Electric pressure washers are a handy tool for cleaning, but they need to be primed before use to ensure optimal performance and avoid long-term damage. Priming the pump is about removing trapped air from the system, which can cause a loss of pressure and cleaning efficiency. This simple process involves checking for air leaks, positioning the washer close to the water supply, and opening the water supply to flush out any air. Modern washers may have self-priming pumps, but it's important to check for air pockets, especially if the machine has been idle. Running water through the pump for 20-30 seconds can help, and some recommend keeping water flowing through the gun during use. Once primed, users can select the appropriate nozzle and turn on the washer, remembering to release pressure after use.

What You'll Learn
Check for air leaks
Before starting your electric pressure washer, it is important to check for any air leaks in the system. This is a crucial step to ensure the machine operates efficiently and safely. Here are some detailed steps to guide you through the process of checking for air leaks:
Begin by inspecting all the connections and fittings on the pressure washer. This includes the hoses, nozzles, and any other attachments connected to the machine. Look for any signs of damage or wear and tear that could potentially cause an air leak. Replace or repair any faulty components before proceeding.
Once the initial inspection is complete, perform a pressure test. Start by ensuring the machine is turned off and disconnected from any power source. Then, using a pressure gauge, measure the pressure in the system. Standard pressure levels vary depending on the model, so refer to your pressure washer's manual for the specific pressure range. If the pressure reading is unstable or deviates from the recommended range, this could indicate an air leak.
With the pressure washer still turned off, carefully examine the seals and gaskets located between the connections and fittings. These components are crucial for maintaining a proper seal and preventing air leaks. Look for any cracks, damage, or signs of deterioration. If the seals or gaskets are compromised, they may need to be replaced to ensure an airtight seal.
After completing the visual inspections, conduct a soap solution test. Prepare a mixture of soap and water and apply it to all connections and fittings using a brush or spray bottle. The soap solution will bubble if air is escaping from any leaks. This method is particularly effective for identifying small or subtle leaks that may not be visible to the naked eye.
Finally, perform a functional test by operating the pressure washer. With the machine turned on and running, listen carefully for any unusual sounds, such as hissing or whistling noises, which could indicate an air leak. Also, pay attention to the performance of the pressure washer. If it struggles to maintain pressure or shows inconsistent performance, this could be a sign of air leakage.
Remember, regularly checking for air leaks is essential to maintain the performance and longevity of your electric pressure washer. By following these steps, you can identify and address any potential issues promptly, ensuring your machine operates safely and efficiently.

Position the pressure washer
To ensure optimal performance when using an electric pressure washer, it is important to position it strategically. Here are some detailed instructions to guide you through the process:
Firstly, place your pressure washer on a flat surface to ensure stability. This is crucial for maintaining a steady workflow and preventing any accidental spills or mishaps.
Secondly, position the pressure washer as close to the water supply as possible. The proximity to the water source is essential for achieving optimal water flow. The shorter the distance between the washer and the water supply, the better the water flow will be, resulting in more efficient cleaning.
If you have a flexible water supply hose, you can move the pressure washer around more freely. However, always be mindful of the distance between the washer and the water supply to ensure uninterrupted water flow.
When positioning the pressure washer, consider any obstacles or hazards that may interfere with your work. Ensure there is enough space to manoeuvre the washer and its accessories comfortably. Additionally, be mindful of your surroundings and avoid placing the washer in areas where the water spray could cause damage, such as near open windows or fragile items.
By following these guidelines, you can effectively position your electric pressure washer to maximise its performance and ensure a smooth and efficient cleaning experience. Remember, strategic placement not only enhances the functionality of your washer but also contributes to a safer and more convenient cleaning process.

Open the water supply
To open the water supply for your electric pressure washer, follow these steps:
First, ensure your pressure washer is positioned on a flat surface. Check that the water strainer is in place and free of debris. Connect one end of a garden hose to the washer, and the other end to your water supply. The closer the pressure washer is to the water supply, the better the water flow. Make sure the hose is not kinked, leaking, or blocked.
Next, attach a high-pressure hose between the spray wand and the pressure washer. Turn on the water supply and allow it to flow freely. Without connecting the high-pressure hose just yet, run water through the pressure washer. This step helps to remove any air and primes the pump. You can open the ball valve on the hose to flush out all the air before it reaches the pressure washer.
Once you have completed these steps, you can continue with the standard operating procedure for your electric pressure washer. Remember to always keep water running through the gun to avoid pumping air through the pump, which can cause damage.

Prime the pump
To prime the pump of an electric pressure washer, you must ensure that there is no air trapped inside the pump. This is because air pockets can cause a loss of pressure, making it difficult for the pump to build up the pressure needed for effective cleaning.
- Check for air leaks: Inspect the suction hose and connections for any leaks. Make sure everything is tightly sealed to prevent air from entering the pump.
- Position the pressure washer: Place your pressure washer close to the water supply for optimal performance.
- Open the water supply: Turn on the water supply and let the water flow freely. Without connecting the high-pressure hose, run water through the pressure washer to remove any air and prime the pump.
- Prime the pump: Most modern pressure washers have self-priming pumps. However, if your pump is not self-priming, you may need to manually prime it by following the next steps.
- Turn off the machine: If your pump is not self-priming, turn off the machine and disconnect the high-pressure water hose and trigger gun.
- Connect the garden hose: With only the garden hose connected, turn on the water source and let the water run through the pump for 20-30 seconds.
- Reconnect the high-pressure hose: Turn off the water and reconnect the high-pressure hose and trigger gun. Your pressure washer should now be primed and ready for use.
It is important to prime your pressure washer pump before each use, especially if it has been idle for a while or if you have changed any hoses or attachments. Regular priming ensures smooth water flow and prevents damage to internal parts.
