If you have ever used a pressure washer, you may have noticed that it sometimes surges or goes through periods of high and low pressure. This can be frustrating, especially if you are trying to do a delicate job like washing your car. There are several reasons why your pressure washer might surge and there are some things you can do to fix the problem.
If your pressure washer is surging, it could be because the pump isn’t working properly. The pump is responsible for creating the pressure that forces water through the nozzle. If the pump isn’t working correctly, the water flow will be interrupted and cause the pressure washer to surge.
Another possibility is that the unloader valve is stuck in the “on” position. The unloader valve controls the amount of water that flows through the pump. If it’s stuck in the “on” position, it will allow too much water to flow into the pump and cause it to surge.
If you’re having trouble with your pressure washer surging, check these two things first. If neither of them seems to be the problem, then you may need to take it to a professional for further diagnosis.

How Do You Fix a Pulsating Pressure Washer?
If your pressure washer is pulsating, it’s usually an indication that the pump isn’t working properly. There are a few things you can try to fix the problem:
- Check the oil level in the pump. If it’s low, add more oil and see if that fixes the issue.
- Inspect the unloader valve and make sure it’s not stuck open. If it is, clean or replace it as needed.
- Examine the pressure relief valve and ensure that it’s not stuck closed. If so, you’ll need to replace it.
- Make sure there’s nothing blocking the water inlet screen or outlet port on the pump.
Pressure Washer Surges When Not Spraying
If you have a pressure washer that is surging when not spraying, there are a few things that could be causing the issue. First, check the pump to see if it is damaged or leaking. If the pump is fine, then the problem may be with the unloader valve.
This valve regulates the flow of water through the pump and can become stuck in the open position, which causes the pressure washer to surge. To fix this, simply clean or replace the unloader valve.
Why Does My Pressure Washer Keep Losing Pressure
If you’re having trouble with your pressure washer losing pressure, there are a few things that could be causing the problem. First, check the inlet water filter to make sure it’s not clogged. If it is, clean or replace it.
Next, check for any kinks or leaks in the hose. If you find any, repair them with duct tape or a hose clamp. Finally, check the pump itself for any cracks or damage.
If you find any damage, you’ll need to replace the pump.
Why Does My Electric Pressure Washer Keep Running
If you’ve ever wondered why your electric pressure washer keeps running even when you’re not using it, you’re not alone. It’s a common problem that can be caused by a few different things. In this blog post, we’ll take a look at the most common reasons for this issue and what you can do to fix it.
One of the most common reasons for an electric pressure washer to keep running is because the water inlet valve is stuck open. This valve is responsible for letting water into the pump, and if it’s stuck open, the pump will continue to run even when you’re not using it. To fix this problem, simply locate the water inlet valve and turn it off.
Another common reason for an electric pressure washer to keep running is because the unloader valve is sticking open. The unloader valve is responsible for releasing pressure from the pump when you’re not using it. If this valve sticks open, the pump will continue to run even when there’s no pressure in the system.
To fix this problem, locate the unloader valve and turn it off.
Finally, another common reason for an electric pressure washer to keep running is because the thermal relief valve is sticking open. The thermal relief valve protects the pump from overheating by releasing excess heat build-up.
If this valve sticks open, the pump will continue to run even when there’s no water flowing through it. To fix this problem, locate the thermal relief valve and turn it off.
Karcher Pressure Washer Surging/Pulsing
If you’re having issues with your Karcher pressure washer surging or pulsing, there are a few things that could be the culprit. First, check to see if the water inlet filter is clogged. If it is, clean or replace it.
Next, make sure that the pump isn’t cavitating by checking the intake hoses for any kinks or blockages. Lastly, if the problem persists, take a look at the pressure relief valve to see if it needs to be adjusted or replaced. By following these simple steps, you should be able to fix the problem and get your pressure washer back up and running smoothly.
Electric Pressure Washer Pulsating
If you are in the market for a pressure washer, you may be wondering about the benefits of an electric pressure washer pulsating. Pulsating pressure washers are designed to create a more powerful cleaning action by rapidly oscillating the water stream. This can be beneficial for many different types of cleaning projects.
Here is a closer look at some of the advantages of using an electric pressure washer pulsating:
1. More Efficient Cleaning –
One of the biggest advantages of using an electric pressure washer pulsating is that it can help to make your cleaning projects more efficient. The rapid oscillation of the water stream helps to loosen and remove dirt and grime more effectively than a traditional pressure washer.
This can save you time when cleaning large areas or tackling tough jobs.
2. Greater Mobility –
Another advantage of electric pressure washers pulsating is that they tend to be much more mobile than their counterparts. This means that you can easily take them with you when traveling or moving around your home or business premises.
Additionally, most models come with wheels which makes them even easier to transport from one location to another.
3. Safer to Use –
Another great benefit of electric pressure washers pulsating is that they are generally much safer to use than traditional gas-powered models. This is because there is no risk of fire or explosion when using these devices.
Additionally, they don’t produce any harmful fumes which makes them ideal for use in enclosed spaces such as garages and workshops.
Pressure Washer Throttle Problems
If you have a pressure washer, you may have experienced throttle problems. The throttle is what controls the amount of water that flows through the pump. If the throttle is not working properly, it can cause the pressure washer to work less efficiently or even stop working altogether.
There are a few things that can cause throttle problems. One is a build-up of dirt and debris in the carburetor. This can be cleaned out with a carburetor cleaner.
Another possibility is that the O-ring on the pump shaft has become damaged and needs to be replaced.
If you are having trouble troubleshooting the problem, take your pressure washer to a repair shop. They will be able to diagnose the problem and fix it so that your pressure washer will work like new again.
Karcher Pressure Washer Pulsing When Not in Use
If you have a Karcher pressure washer that is pulsing when not in use, there are a few things you can check to troubleshoot the issue. First, make sure that the water supply to the pressure washer is turned on. If it is, then check the inlet screen for debris and clean it if necessary.
Next, check the unloader valve to see if it is stuck in the bypass position. If so, simply turn it back to the operating position. Finally, if none of these solutions solve the problem, you may need to replace the pump.

How Do I Fix My Pressure Washer from Surging?
If you’re experiencing surging with your pressure washer, there are a few things you can check to try and fix the issue. First, take a look at the air filter and see if it’s clean. If it’s dirty, replace it with a new one.
Next, check the spark plug and make sure it’s not fouled. If it is, clean or replace it as needed. Finally, check the fuel filter and make sure it’s not clogged.
If it is, replace it with a new one.
Why Does My Pressure Washer Rev Up And Down?
If your pressure washer is revving up and down, it’s likely because the engine is having trouble staying running. This can be caused by a number of things, including:
Dirty spark plugs: Over time, spark plugs can become coated with dirt and debris, which can prevent them from firing properly.
Replacing your spark plugs is an easy way to fix this problem.
Faulty carburetor: A dirty or faulty carburetor can also cause your pressure washer’s engine to rev up and down. Cleaning or rebuilding the carburetor should fix the problem.
Low oil level: If your pressure washer’s oil level is low, it can cause the engine to misfire, resulting in a revving sound. Be sure to check the oil level regularly and top it off as needed. These are just a few of the potential causes of a revving pressure washer engine.
If you’re still having trouble after trying these tips, take your machine to a professional for diagnosis and repair.
How Do I Stop My Pressure Washer from Pulsing?
If your pressure washer is pulsing, it could be due to a few different issues. First, check to see if the pump is cavitating. This happens when the pump isn’t getting enough water and can cause it to pulse.
Make sure the hose is fully connected and there are no leaks. If the problem persists, you may need to replace the pump. Another possible issue could be a clogged nozzle.
Remove the nozzle and clean it out with a wire brush or toothpick. If that doesn’t work, try replacing the nozzle altogether. Finally, if your pressure washer has an adjustable unloader valve, make sure it’s set properly.
If it’s not, water can build up in the pump and cause pulsing.
Why is My Gas Pressure Washer Pulsing?
If your gas pressure washer is pulsing, it could be due to a few different reasons. The most common reason is that the pump is not primed. This can happen if the water supply has been turned off or if the unit has been sitting for a while and the water in the pump has evaporated.
To fix this, simply turn on the water supply and let the unit run for a few minutes until it builds up enough pressure to start spraying evenly again. Another reason why your pressure washer may be pulsing is because of an airlock. This happens when there is air in the line between the pump and the nozzle.
To get rid of an air lock, turn off the unit and hold down the trigger on the wand until all of the water has sprayed out. Then, turn it back on and resume using it as normal. Finally, pulsing can also be caused by a clogged nozzle.
If your nozzle is blocked, simply remove it and clean it out with a paper clip or similar object. Be sure to also check for any other blockages in your hose before reattaching everything and turning the unit back on.
Conclusion
If your pressure washer is surging, it could be because the pump isn’t primed properly. To prime the pump, start by filling the reservoir with water and then running the engine for a few minutes without turning on the pump. Once the engine is running, turn on the pump and let it run until water starts coming out of the nozzle.
If your pressure washer still surges after priming the pump, it could be because of a number of other factors, including a dirty air filter or an incorrect setting on the pressure regulator.
