What Causes a Pressure Washer to Pulsate?

Homeowners often encounter the issue of pulsating pressure washers, which can be quite frustrating. However, diagnosing the underlying cause of the problem is crucial for effectively resolving it.

One of the most common causes of pulsating in a pressure washer is air in the pump. This occurs when there is an inadequate seal between the pump and its housing, allowing air to enter and create turbulence within the system. To fix this, you need to check all connections for tightness and replace any worn or damaged seals.

Another potential cause could be incorrect nozzle size selection. If you use a nozzle that has too small an opening, it will restrict water flow which can lead to pulsation issues as well as reduced cleaning power from your machine. Always make sure you select nozzles with appropriate openings for your specific model of pressure washer before using them on projects around your home or garden.

A faulty unloader valve may also be responsible for pulsation problems with your machine. The unloader valve helps regulate water flow by controlling how much water enters into the pump chamber at one time – if it fails then it won’t be able to do its job properly, resulting in uneven pulses coming out from your machine’s wand tip instead of steady streams of pressurised water like normal operation should produce.

Finally, some models have built-in regulators that help control output pressures – these can become clogged over time due to debris build up inside them which will result in pulsing during operation as well. As a result, it’s crucial to frequently inspect and clean these as needed.

Pressure washers can pulsate due to a number of different causes, such as an incorrect nozzle setting or a clogged filter. Now that we understand what causes the issue, let’s look at how to fix it.

 
Key Takeaway: Pulsating pressure washers can be caused by air in the pump, incorrect nozzle size selection, faulty unloader valve or clogged regulators. Regularly check and clean all connections for tightness and replace worn seals to ensure optimal performance.

How to Fix a Pulsating Pressure Washer

Pressure washers are a great tool for cleaning outdoor surfaces, but they can be temperamental. If your pressure washer is pulsating, it could be due to several different issues. In this guide, we’ll walk you through how to troubleshoot and fix a pulsating pressure washer.

Check for Air in the Pump: The first step is to check if there is air in the pump. To do this, turn off the power and release any remaining water from the hose by squeezing the trigger on your gun or wand until no more water comes out. Then remove the nozzle tip from your gun or wand and look inside for any bubbles that may indicate air trapped in the pump. If you find bubbles present, then you will need to bleed them out of your system before continuing with other repairs.

Replace Nozzle Tip: Another possible cause of pulsation is an old or worn-out nozzle tip on your gun or wand. This can happen over time as dirt and debris build up around it which restricts its flow rate and causes uneven spraying patterns when used at high pressures. To fix this issue, simply replace your existing nozzle tip with a new one that matches its size and shape exactly so that it fits snugly into place without any gaps or leaks around it.

Adjust Unloader Valve: Lastly, if all else fails then you may need to adjust the unloader valve on your machine which regulates how much water flows through it at any given time depending on what type of job you are doing (i.e., light cleaning vs heavy duty scrubbing). To make adjustments here just follow instructions provided by manufacturer as each model varies slightly in terms of how these valves work together with other components within their systems such as pumps etc.

By following these steps, you can easily fix a pulsating pressure washer. Now that your machine is in working order, it’s important to keep up with regular maintenance to ensure its longevity.

 
Key Takeaway: Key takeaway: To troubleshoot a pulsating pressure washer, check for air in the pump, replace the nozzle tip, and adjust the unloader valve. Regular maintenance tasks such as replacing hoses and checking nozzle tips should also be done to ensure optimal performance.

Tips for Maintaining Your Pressure Washer

Maintaining your pressure washer is essential for keeping it in good working order and preventing it from pulsating. Here are some tips to help you keep your pressure washer running smoothly:

1. Use the Correct Nozzle Size: It’s important to use the correct nozzle size when using a pressure washer. Using a nozzle that is too small can cause water to back up into the pump, resulting in pulsation. To avoid this, make sure you select the right nozzle size for your job.

2. Check for Air in the Pump: If air gets trapped inside of your pump, it can cause pulsation or even damage other components of your machine over time. To prevent this from happening, regularly check for air bubbles coming out of any hoses connected to the pump and remove them if necessary.

3. Clean Out Any Debris: Over time, debris such as dirt and grime can build up inside of your pressure washer’s pipes and hoses which can lead to blockages and reduce its performance significantly. Regularly cleaning out any debris will ensure that all parts are functioning properly and will also help prevent pulsations caused by clogged pipes or hoses.

4 . Check Your Hose Connections: Loose hose connections can also be responsible for causing pulsations in a pressure washer so make sure they’re securely fastened before each use. Additionally, inspect all seals on both ends of each hose connection periodically to ensure there aren’t any leaks which could result in water not flowing correctly through the system.

5 . Inspect Pressure Washers Components: Make sure all components such as nozzles, filters, O-rings, gaskets etc., are free from wear & tear or damage. Replace these parts if necessary as worn out components may lead to reduced performance & efficiency levels as well as possible problems with pulse control settings.

6 . Perform Regular Maintenance Checks: In addition to inspecting individual components, perform regular maintenance checks on your entire machine including checking oil levels & replacing filters where needed ( depending on the type ) This will help keep everything running smoothly & efficiently while helping extend its lifespan overall.

If you have followed all these steps but still experience issues with pulsing, then it is best practice to call an experienced professional who specializes in servicing power washing equipment. They will be able to identify what needs fixing quickly and get you back up and running again without delay.

 
Key Takeaway: To keep your pressure washer running smoothly and prevent pulsation, regularly check for air bubbles in the pump, clean out any debris, securely fasten hose connections, inspect components for wear & tear and perform regular maintenance checks.
