Electric pressure washers are effective devices used for various cleaning purposes. However, they are prone to damages that require repair or replacement. Before attempting to fix an electric pressure washer, it is important to unplug the device from its power source for safety reasons. Basic troubleshooting can help identify the issue, such as checking for clogs, water supply, leaks, or a clogged air filter. If the washer is not starting, ensure there is gas in the engine and that it is not old or contaminated. If the problem persists, check the pump for any leaks or damaged seals and replace them if necessary. In some cases, it may be more cost-effective to replace the entire washer, especially if repairs become frequent or expensive. Regular maintenance, including inspecting, cleaning, and following the manufacturer's guidelines, can help extend the lifespan of your electric pressure washer.

What You'll Learn
Check for clogged air filters, old gas, or blocked nozzles
If your electric pressure washer isn't performing well, one of the first things you should check for is clogged filters. Electric pressure washers have one type of filter—water inlet filters—which stop waterborne dirt in your water supply hose from entering the pressure washer and disrupting the flow. Over time, these filters can become clogged with dirt, leading to reduced water pressure. To clean your water inlet filter, locate the cylindrical fitting where your garden hose plugs into your pressure washer. Loosen and remove the fitting with an adjustable wrench. Depending on the style of inlet filter, you may be able to remove the inner cylindrical screen filter by hand, or you may need to separate the two halves of the fitting with your wrench. Rinse the inner filter screen with water, gently scrubbing away any visible dirt with an old toothbrush. Continue until the screen appears clean, then blow on one end to check that air passes through easily.
If your pressure washer has been losing power or stalling, the problem may lie with the air filter. Dust and debris are naturally drawn toward the engine as the pressure washer runs, and this unwanted material can build up on the air filter over time, reducing airflow to the engine and causing a drop in power. To clean the air filter, first locate the air filter cover, a rectangular plastic shroud near the gas tank and carburetor. Remove the cover by unthreading the nut holding it down or pulling the release tabs on the sides, depending on your model. Locate the air filter inside the housing—it could be a simple rectangle of foam, a pleated paper rectangle, or a pleated paper cylinder encased in a flexible foam cover. Use an air compressor and spray nozzle to remove any loose debris from inside the housing, making sure to hold the air filter in place with one hand. If you don’t have an air compressor, wipe out the housing with a dry disposable shop towel. If the air filter is visibly damaged, skip the cleaning and purchase a replacement of the same type.
Old gas in your pressure washer can also cause issues. If you haven't used your pressure washer in a long time and forgot to drain the gas, it may have become stale and caused varnish and deposits inside of the carburetor. In this case, you should drain the fuel tank and the carburetor.
Finally, if you're experiencing issues with your pressure washer, it's possible that the nozzle is clogged. This can happen if debris enters the system, for example through an old hose. If you have access to another pressure washer, you can try to dislodge the debris by blasting the tip of the plugged washer. Alternatively, try slowly unscrewing the quick connect to release the pressure.

Inspect the hose for kinks or blockages
When troubleshooting an electric pressure washer, it is important to check for kinks or blockages in the hose. Begin by visually inspecting the hose for any signs of kinks or bends. Kinks in the hose are common and can form over time, resulting in reduced water pressure. If no kinks are visible, the next step is to check for blockages.
To check for blockages, start by attaching one end of the hose to a water supply and letting water run through it. If water flows out of the other end without any obstruction, there are no blockages. However, if water fails to come out, the hose is likely blocked. In this case, try to remove the blockage by massaging the hose to dislodge any trapped debris.
After clearing any kinks or blockages, carefully inspect the hose for any tears or leaks. Over time, hoses can develop tears and leaks due to natural wear and tear, sharp objects, or improper storage. If any tears or leaks are found, the hose must be replaced to ensure the safe and proper functioning of the pressure washer.
It is important to note that the hose is a crucial component of an electric pressure washer, connecting the trigger gun to the pump. To maintain the performance of the pressure washer, it is essential to keep the hose in good condition, free from kinks, blockages, tears, and leaks. By following these steps, you can effectively troubleshoot and address any issues related to the hose, ensuring optimal water pressure and flow during operation.

Ensure the rocker switch is on
If your electric pressure washer is not working, one of the first things you should check is whether the rocker switch (or kill switch) is in the 'on' position. This is because, if the switch is not engaged, there is typically an additional safety switch that will prevent the machine from operating.
The rocker switch is an important component of the pressure washer, and if it is not in the 'on' position, the machine will not start. This is a simple yet crucial step in troubleshooting your electric pressure washer.
It is also important to note that if your pressure washer is experiencing power issues, it could be due to a clogged air filter or old gas. Other common causes of power loss include dirt, debris, or corrosion blocking the nozzles, as well as low house water pressure or a kinked or blocked hose.
If you are unsure about the location of the rocker switch or how to access it, refer to your pressure washer's user manual or seek guidance from a professional technician. They can guide you through the process of locating and engaging the rocker switch to ensure it is in the correct position.
By ensuring the rocker switch is on, you can eliminate a simple yet critical issue that may be preventing your electric pressure washer from functioning properly.

Check gas is fresh and not contaminated
If your electric pressure washer engine doesn't start, it could be due to old or contaminated gas. Old gas loses its volatility and turns into a gummy varnish, clogging the carburetor and restricting the flow of gasoline to the combustion chamber. To check if your gas is fresh and not contaminated, start by pouring some out and observing its colour. Fresh gas should be very clear with little tint, while usable gas will have a slight brown tint. Bad gas, on the other hand, will have a dark brown tint. If you have access to fresh gas, you can compare the colours to determine if your gas is still usable.
Alternatively, you can compare the colour of the suspect gas to that of A&W Cream Soda. Pour the gas into a clean and dry 2-litre bottle and buy a 2-litre bottle of A&W Cream Soda for comparison. If the colours are similar, it indicates that the gas is bad and should not be used in your car. However, it can still be used as a degreaser.
Another method to check the freshness of gas is to blend it with fresh gas at a weak ratio. For example, you can mix one gallon of old gas with five gallons of new gas and use it in your vehicle. This approach allows you to gradually use up the old gas without risking damage to your engine. However, it is important to note that this method may not be suitable for all vehicles, especially those that require 93 octane and are more prone to detonation.
If you are unsure about the freshness of your gas, it is best to dispose of it safely and legally at a local hazardous waste disposal facility. This way, you can avoid potential engine problems and ensure the proper handling of old gas.
