Pump Protector Maintenance: Greenworks Electric Guide

If you want to protect your electric Greenworks pressure washer, there are several steps you can take. Firstly, you should roll up the electrical cord and hose neatly, ensuring there are no kinks. You should also avoid storing the machine in a freezing room or near a furnace or other sources of heat, as this may dry out the pump seals. To prevent excess air in the pump, you can turn on the garden hose and leave the pressure washer turned off, squeezing the trigger for about three minutes. This will allow water to run through the unit with no pressure, removing any air stuck in the pump. You can also purchase a pressure washer pump saver or protector, which can be bought at most hardware stores.

Use a pressure washer pump saver

A pressure washer pump saver is highly recommended by manufacturers to protect pressure washer pumps against corrosion. It is especially important to use a pump saver before storing your machine for the winter and if it's not going to be run for a significant time.

Some general advice for using a pump saver is to use it before storing the machine. For home use/DIY washers, the general advice is to always use a pump saver before putting the machine away for the winter and if it's not going to be run for a couple of months or longer.

One user on Reddit shared their experience with not using a pump saver in their Karcher pressure washer. Within a couple of years, the pump would not shift to high pressure when they triggered the wand. Their friend, a small engine mechanic, recommended they use Pump Guard, an antifreeze and anti-corrosion additive. Even small amounts of corrosion in the bore of the unloader valve will cause the valve to stick and keep the pump from producing pressure.

Another user on Reddit shared that they never used a pump saver with their electric pressure washer and it still works fine. They recommend storing the washer somewhere it won't freeze over the winter, not running it without water, releasing the pressure if you're not going to be using it for a while, keeping it from freezing, and not using bleach as it will cause the inside of the pump to rust.

If you want to save money, you can make your own pump saver at home by mixing RV antifreeze (non-toxic, $2/gal) and canola oil (or expired oil, which is free).

Greenworks recommends using a pressure washer pump saver and storing the machine in a room that does not reach freezing temperatures.

Store the machine and accessories in a room above freezing

Storing your Greenworks electric pressure washer and its accessories in a room that does not reach freezing temperatures is essential for maintaining the machine's optimal condition. Here are some detailed instructions to follow:

Firstly, identify a suitable storage location. Choose a room that remains above freezing, as cold weather, especially below-freezing temperatures, can be detrimental to machines involving water, such as pressure washers. Ensure that the room is temperature-controlled and maintained between 50 and 80 degrees Fahrenheit. Avoid storing the machine near a furnace or other sources of heat, as excessive heat can dry out the pump seals.

When preparing the machine for storage, it is crucial to use a pressure washer pump saver. Follow the instructions provided with the pump saver to ensure proper application. Additionally, roll up the electrical cord and hose neatly, making sure there are no kinks. Store the machine and its accessories off the floor and in a dry, well-ventilated area.

To further protect your pressure washer, consider using waterproof containers for additional protection against moisture. You can also include silica gel packets inside the storage box to capture any excess humidity, as moisture is one of the biggest culprits for electronics damage.

By following these instructions, you can effectively store your Greenworks electric pressure washer and its accessories, ensuring they remain in good condition and are protected from the potential harm caused by freezing temperatures. Remember, gradual temperature adjustment is crucial, so allow the machine to acclimate to room temperature before use if it has been stored in a colder environment.

Clean nozzles with vinegar and warm water

To pump protector in an electric Greenworks machine, it is recommended to use a pressure washer pump saver. You can follow the instructions provided with the pump saver. Additionally, it is advised to roll up the electrical cord and hose neatly, ensuring no kinks are present. The machine should be stored in a room that does not experience freezing temperatures or proximity to heat sources, as this can dry out the pump seals.

Now, let's focus on cleaning nozzles with vinegar and warm water. This process can help remove any dust, dirt, or calcium buildup that may have accumulated over time and caused the pressure washer to malfunction. Here are the steps:

• Prepare a 50/50 mixture of white vinegar and warm water in a bowl or container.
• Soak the nozzles in this mixture for a minimum of 15 minutes.
• Use a nozzle cleaning tool or a paper clip to poke through the end of the nozzle hole and remove any debris.
• Rinse the nozzles with warm water.
• If needed, scrub the nozzle's holes with a soft-bristled toothbrush or a microfiber cloth dipped in the vinegar solution. Pay extra attention to any crevices or attachments to remove any remaining residue.
• Rinse the nozzles again with warm water to remove any residual vinegar solution.
• Dry the nozzles with a clean cloth before reassembling them.

It is important to note that you should not use a metal object to clean the nozzles, as it can cause damage. Additionally, always wear gloves when handling chemical residues, and ensure that the cleaning solution is free of debris and suitable for plastic materials if your nozzles are made of plastic.

Remove air from the pressure washer

To remove air from your Greenworks electric pressure washer, you must first set up the unit as usual, ensuring it is not connected to an extension cord. Turn the pressure washer off and remove any nozzle connected to the end of the wand. With the pressure washer still off, turn on your garden hose and squeeze the trigger for about 3 minutes, allowing water to run through the unit at no pressure. This will bleed the unit of any air that may be stuck in the pump. After 3 minutes, turn the unit on and reinstall a clean nozzle.

If there is still no water flow from the pump, it could be due to a blockage in the inlet or outlet valves. Inspect each valve and remove any debris or obstructions. If the valves are clear, the problem could be due to a damaged or broken pump, which may need to be replaced. Most pressure washer pumps require oil to operate properly, so check the oil level and add more if necessary.

If your pressure washer is running fine but not producing any pressure, there could be air in the pump, damaged seals or valves, or a malfunctioning pressure regulator. To check for air in the pump, inspect the water inlet hose from where the pressure washer gets water from the tank. Ensure the dust filter is in place and remove any dirt or debris. Allow water to flow through the machine's pump for at least two minutes with the machine turned off.

If you are still unable to remove the air from your pressure washer, you may need to purchase a pressure washer pump saver, which can be bought at most hardware stores.

Ensure 10 feet of unrestricted garden hose

To ensure your Greenworks electric pressure washer is in optimal condition, it is important to follow the manufacturer's recommendations for maintenance and usage. One such instruction is to ensure 10 feet of unrestricted garden hose between the hose connection and the unit. Here's a detailed guide on this specific aspect:

Uncoil the Hose

Firstly, it is important to uncoil the garden hose to its full length. This ensures that there are no kinks or tangles that could restrict water flow or cause damage to the hose. By uncoiling the hose, you allow for uninterrupted water flow and prevent any potential blockages.

Minimum Hose Length

The Greenworks manual specifically instructs users to maintain a minimum of 10 feet of unrestricted garden hose between the water intake and the hose faucet or shut-off valve. This length is crucial to ensure proper water flow and pressure. Any kinks or restrictions within this length will negatively impact the performance of your pressure washer.

Cleaning the Hose

Before connecting the hose to the machine, it is recommended to run water through the hose for approximately 30 seconds to clean any debris that may have accumulated. This step ensures that dirt or residue does not enter the machine and potentially cause blockages or affect water flow.

Inspecting the Screen

After running water through the hose, it is important to inspect the screen in the water intake. If the screen appears damaged, it is crucial to refrain from using the machine until the screen has been replaced. A dirty screen should be cleaned before connecting the hose to the machine.

Connecting the Hose

With the hose faucet turned off, you can now attach the end of the garden hose to the water intake. Tighten the connection by hand only. Do not overtighten, as it may damage the connection or affect the water flow. Now, your garden hose is properly connected and ready for use with your Greenworks electric pressure washer.

By following these steps, you ensure that your garden hose meets the recommended length and is free from restrictions, thus optimizing the performance of your Greenworks electric pressure washer. Remember to regularly inspect your hose for any signs of wear and tear, and always store it properly to maintain its condition.
