How to fix pressure washer pulsing

If you’ve ever experienced the problem of your pressure washer constantly pulsing, you know how frustrating it can be. So why does it keep happening? Well, there are a few possible reasons. One common cause is low water pressure.

If the water supply to your pressure washer isn’t strong enough, it can cause the machine to pulsate. Another possibility is a clogged or dirty nozzle. If dirt or debris gets stuck in the nozzle, it can disrupt the flow of water and lead to pulsating.

Additionally, a worn-out or damaged pump can also cause pulsing. Over time, the pump can wear down and lose its ability to maintain a consistent water flow. Luckily, there are some easy fixes for this issue.

First, check your water source and make sure the pressure is adequate. If it’s not, try adjusting the water flow or cleaning out any filters that may be clogged. If the nozzle is the problem, remove it and clean it thoroughly.

And if it’s a worn-out pump, you may need to replace it. By addressing these potential causes, you can eliminate the pulsing and get your pressure washer running smoothly once again.

Step 1: Check for air in the water supply

pressure washer pulsing If your pressure washer is pulsing instead of providing a consistent stream of water, there are a few potential causes and solutions you can try. One common issue that can cause this pulsing is air in the water supply. Air bubbles can disrupt the flow of water and create a pulsing effect.

To check for air in the water supply, start by inspecting the inlet hose and make sure it is properly connected and not kinked or twisted. You can also try running the pressure washer without the high-pressure nozzle to see if the pulsing persists. If the pulsing stops, it may indicate that there is air trapped in the nozzle.

To remove the air, you can try running water through the nozzle or disassembling it and cleaning any debris or blockages. Another option is to bleed the air out of the pressure washer system by turning it on and off a few times. If these steps don’t solve the problem, there may be other issues causing the pulsing, such as a faulty pump or unbalanced load.

In these cases, it’s best to consult a professional for further assistance.

Step 2: Inspect the inlet filter

Over time, mineral deposits and other debris can build up, blocking the flow of water and causing the pulsing effect. To fix this problem, start by turning off the pressure washer and disconnecting the spray gun from the hose. Inspect the nozzle and spray gun for any signs of clogs, such as visible debris or a decreased flow of water.

If you notice any clogs, use a small wire brush or a pin to carefully remove the blockage. Once the nozzle and spray gun are clear, reattach them to the pressure washer and test the water flow. If the pulsing issue persists, you may need to check for clogs in other parts of the pressure washer system, such as the wand or the hose.

However, by regularly inspecting and cleaning the nozzle and spray gun, you can prevent clogs and ensure a consistent water flow while using your pressure washer.

Step 4: Adjust the pressure output

Step 5: Clean or replace the unloader valve

The unloader valve is responsible for regulating the pressure inside the pump and releasing excess pressure when the trigger on the wand is released. Over time, the unloader valve can become clogged with dirt, debris, or scale, causing it to stick open or closed.

This can result in a pulsing effect as the pressure builds up and is released in an uneven manner. To fix this issue, you can try cleaning the unloader valve with a mild detergent and a brush. If cleaning doesn’t solve the problem, you may need to replace the unloader valve entirely.

This is a relatively simple process that can be done at home with basic tools. By cleaning or replacing the unloader valve, you should be able to fix the pulsing and enjoy a consistent water pressure while using your pressure washer.

Step 6: Repair or replace any damaged parts

Preventing pressure washer pulsing

Have you ever wondered why your pressure washer keeps pulsing? It can be quite frustrating, especially when you’re trying to get a job done quickly and efficiently. There are a few possible reasons for this pulsing phenomenon that are worth exploring. One common cause is air in the system, which can disrupt the flow of water and result in that annoying pulsing sensation.

To fix this issue, you can try purging the air from the system by running the pressure washer with the trigger gun closed until a steady flow of water is achieved. Another possible cause of pulsing is a clogged nozzle or spray tip. When debris gets stuck in the nozzle, it can cause the water to come out in a sporadic manner, leading to pulsing.

In this case, you can simply remove the nozzle and clean it thoroughly to resolve the issue. Additionally, a worn or damaged pump can also cause pulsing in a pressure washer. If you’ve checked for air in the system and cleared any clogs but are still experiencing pulsing, it may be time to inspect the pump and replace any worn or damaged parts.

By addressing these common causes of pressure washer pulsing, you can ensure a smooth and uninterrupted workflow the next time you tackle a cleaning project.

Regular maintenance and cleaning

To avoid this issue, it is important to regularly check and clean the nozzle, hose, and trigger gun. These components can become clogged with debris and buildup over time, causing the pressure washer to pulsate. Additionally, it is recommended to inspect the water inlet filter and clean or replace it if necessary.

A dirty filter can restrict the flow of water and contribute to pulsing. In some cases, adjusting the pressure regulator on the pressure washer can also help to prevent pulsing. By properly maintaining and cleaning your pressure washer, you can ensure a smooth and efficient cleaning experience without any pulsing issues.

So, don’t forget to give your pressure washer some TLC to keep it performing at its best!

Using the correct size nozzles and spray gun

Pulsing occurs when the spray gun releases uneven bursts of water, which can make cleaning tasks challenging and less efficient. One of the main causes of pulsing is using the wrong size nozzle.

If the nozzle is too small, it can cause excessive pressure buildup, resulting in pulsing. On the other hand, if the nozzle is too large, it may not provide enough pressure, leading to a weak and inconsistent stream. It’s essential to choose a nozzle size that matches the pressure rating of your pressure washer to ensure smooth and consistent water flow.

Additionally, using the correct spray gun can also help prevent pulsing. A spray gun with a pressure regulator allows you to adjust the water pressure to the desired level, effectively eliminating pulsing. By using the right nozzle size and spray gun, you can ensure a steady and powerful water stream, making your pressure washing tasks much more efficient and effective.

Proper storage and winterization

Proper storage and winterization of your pressure washer is essential for maintaining its performance and longevity. One common issue that can arise during the winter months is pressure washer pulsing. This occurs when the pressure fluctuates and causes an uneven flow of water.

Not only is this frustrating, but it can also damage your equipment. To prevent pressure washer pulsing, there are a few steps you can take. First, make sure to drain all water from the pressure washer and hoses after each use.

Any remaining water can freeze and cause blockages in the system. Next, store your pressure washer in a dry and climate-controlled area to protect it from extreme temperatures. If you live in an area with particularly cold winters, you may want to consider using a winterizing solution to remove any remaining water from the system.

By taking these precautions, you can ensure that your pressure washer is ready to use when warmer weather rolls around.
