Why Is My Sunjoe Pressure Washer Pulsating? Troubleshooting Tips.

why is my sunjoe pressure washer pulsating

If there’s one thing more frustrating than a dirty patio or a grimy car, it’s a pressure washer that just won’t work properly. You’ve got your SunJoe pressure washer all set up and ready to go, but instead of a steady stream of water, you’re getting a pulsating spray. It’s enough to make you want to tear your hair out.

But fear not, we’re here to help you unravel the mystery behind your pulsating pressure washer. Why is it happening? Well, it’s like trying to drink water from a straw that’s been pinched shut – the water can’t flow smoothly through the nozzle, so it comes out in bursts. The same principle applies to your pressure washer.

If there’s a blockage or restriction in the system, it can cause the water to pulsate instead of flowing in a steady stream. So, let’s roll up our sleeves and get to the bottom of this pulsating problem.


Are you experiencing a pulsating issue with your SunJoe pressure washer? Don’t worry, you’re not alone. Many people encounter this problem, and there are a few potential reasons behind it. One possible cause could be a clogged nozzle or spray tip.

Over time, debris and dirt can accumulate in the nozzle, leading to an inconsistent flow of water and causing the pulsating effect. Another reason could be a blockage in the water supply. If there is a restriction or obstruction in the hose or water source, it can disrupt the water flow and result in pulsation.

Additionally, a worn-out or damaged pump could also be the culprit. If the pump is not functioning properly, it can create irregular pressure and cause the pulsation. So, the next time you encounter this issue with your SunJoe pressure washer, try cleaning the nozzle, checking for any blockages in the water supply, or inspecting the condition of the pump.

And remember, if all else fails, reach out to a professional for assistance.

One possible reason is that there is air in the system. This can occur if there is a leak in the hose or fittings, or if the water supply is not fully turned on. Another possible reason is that the pump may be clogged with debris.

This can happen if you’re using water from a well or other non-filtered source. It’s important to regularly clean and maintain your pressure washer to prevent these issues from occurring. If you’re unsure of the cause of the pulsating, it may be best to consult the user manual or contact SunJoe customer support for assistance.

FAQ 1: How do I fix my Sun Joe pressure washer if it’s pulsating? Answer: If your Sun Joe pressure washer is pulsating, it may be due to a clogged nozzle or hose. Try cleaning the nozzle and hose to remove any debris or blockages. If the issue persists, check the water source for any restrictions or low water pressure. You may also want to inspect the inlet filter to ensure it is clean and not obstructed. FAQ 2: Why is my Sun Joe pressure washer pulsating when I use it with a garden hose? Answer: When using a garden hose with a Sun Joe pressure washer, pulsation can occur due to low water flow or insufficient water pressure. Ensure that the garden hose is fully open, and check for any kinks or blockages. If the water pressure from the hose is low, you may need to use a higher-pressure water source, such as a pressure washer pump connected to a water supply. FAQ 3: What should I do if my Sun Joe pressure washer is pulsating while using detergent? Answer: If your Sun Joe pressure washer is pulsating while using detergent, it could be due to the detergent mix being too thick or inconsistent. Make sure to follow the manufacturer’s instructions for mixing the detergent properly. If the problem persists, try diluting the detergent with water or switching to a different detergent brand that is compatible with your pressure washer. FAQ 4: How can I prevent pulsation in my Sun Joe pressure washer? Answer: To prevent pulsation in your Sun Joe pressure washer, ensure that the water supply is free from any restrictions or low pressure. Regularly clean and maintain the nozzle, hose, and inlet filter to prevent blockages. Avoid using thick or inconsistent detergent mixes that can cause uneven flow and pulsation. Additionally, always use the correct nozzle size for your desired pressure level. FAQ 5: Is it normal for a Sun Joe pressure washer to pulsate slightly? Answer: A slight pulsation in a Sun Joe pressure washer can be normal, especially if you are using a lower-pressure setting. However, excessive or consistent pulsation may indicate a problem, such as a clogged nozzle or hose, low water pressure, or an issue with the detergent mix. Always monitor your pressure washer for any irregularities and address them accordingly. FAQ 6: Can using an extension cord cause pulsation in a Sun Joe pressure washer? Answer: Yes, using an extension cord that is not rated for the power requirements of your Sun Joe pressure washer can cause pulsation. The extension cord may not provide sufficient power, leading to inconsistent flow and pressure. It is recommended to use a cord that is specifically designed for outdoor use and has the appropriate power rating for your pressure washer. FAQ 7: Why does my Sun Joe pressure washer pulsate only when I release the trigger? Answer: If your Sun Joe pressure washer only pulsates when you release the trigger, it may be due to the unloader valve or pressure relief valve. These valves are designed to regulate the pressure and prevent damage to the pump. If the valves are faulty or not adjusted properly, they can cause pulsation when the trigger is released. Contact the manufacturer or a qualified technician for assistance in inspecting and adjusting these valves.
