When you pull the trigger on a pressure washer, it should start up without any issues. However, if your machine starts to pulse when you pull the trigger, there are a few things that could be going wrong. The most common reason for this problem is that the pump isn’t getting enough water.
This can be caused by a number of different things, including a clogged inlet filter or a kink in the hose. Another possibility is that the unloader valve is stuck open, which will cause the pump to cycle on and off very quickly. If you’re not sure what’s causing your pressure washer to pulse, take it to a qualified technician for diagnosis and repair.
Has your pressure washer ever given you a pulse when you pulled the trigger? If so, you’re not alone. Many pressure washer owners have experienced this issue at one time or another.
While it can be annoying, there is usually a simple fix.
There are two main reasons why your pressure washer may pulse when you pull the trigger. The first is that the pump isn’t getting enough water.
This can happen if the hose isn’t fully connected to the faucet or if there is a kink in the hose. If this is the case, simply turn on the water supply and make sure there is a strong flow of water before starting your pressure washer again.
The second reason why your pressure washer may pulse is because the unloader valve is stuck open.
The unloader valve releases water from the pump when it’s not in use and prevents backflow into the pump. If this valve becomes stuck open, it will cause pulsing as well as loss of power and decreased water pressure. To fix this, simply locate and clean out any debris that may be causing the valve to stick open.
If you’re still having issues with your pressure washer pulsing after trying these tips, then it’s time to call in a professional for help.

Pressure Washer Surges When Not Spraying
If you have a pressure washer that surges when not spraying, there are a few things that could be causing the problem. First, check to see if the pump is getting enough water. If it isn’t, then the pump will try to make up for the lack of water by increasing the pressure, which can cause surging.
Second, check the unloader valve to see if it’s sticking or if there is something blocking it from opening all the way. If the unloader valve isn’t working properly, then the pressure will build up in the pump and cause surging. Finally, check your hoses and fittings to make sure there are no leaks.
Leaks can also cause surging because they allow air into the system which throws off the balance of pressure in the pump.
If you’re having trouble with your pressure washer surging when not spraying, take a look at these potential causes and see if you can fix the problem yourself. If not, then it may be time to call in a professional.
Karcher Pressure Washer Surging/Pulsing
Are you having issues with your Karcher pressure washer surging or pulsing? If so, you’re not alone. This is a common problem that can be caused by a variety of things.
In this article, we’ll go over some of the most common causes and how to fix them.
One of the most common causes of pressure washer surging is an issue with the pump. The pump is what generates the high-pressure water that comes out of the wand.
If there’s an issue with the pump, it can cause the machine to surge or pulse. There are a few things that can cause pump problems:
-The water inlet filter may be clogged, preventing enough water from reaching the pump.
Make sure to clean or replace the filter if this is the case.
-There could be something caught in the impeller (the part of the pump that moves water). Remove anything that might be blocking it and make sure it’s clear before using the pressure washer again.
-The O-rings inside the pump may be worn out or damaged. These need to be replaced periodically anyway, so if they’re causing issues, it’s probably time for new ones anyway. You can get replacement O-rings at most hardware stores.
Another possible cause of surging is an issue with dirty spark plugs . Over time, deposits can build up on spark plugs and prevent them from firing properly. This will cause your engine to run erratically and can lead to surging or pulsing .
To clean spark plugs , remove them from your engine and scrub them with a wire brush dipped in solvent . You should also check your air filter ; if it’s excessively dirty , replace it . A dirty air filter can also lead to engine problems .
Lastly , check for leaks in your hoses or fittings . Pressure washers generate a lot of force , so even small leaks can result in big problems . Make sure all connections are tight and there are no cracks or holes in any of your hoses .
Hopefully one of these tips will help you fix your surging / pulsing pressure washer !
Pressure Washer Throttle Problems
If your pressure washer throttle isn’t working properly, it can be a real pain. There are a few things that could be causing the problem, so it’s important to troubleshoot and figure out what the issue is.
One possible issue is that the throttle cable is damaged or frayed.
If this is the case, you’ll need to replace the cable. Another possibility is that there’s something wrong with the throttle itself. This is a more serious problem and will likely require professional help to fix.
If your pressure washerthrottle isn’t working properly, don’t despair! With a little troubleshooting, you should be able to identify and fix the problem in no time.
Karcher Pressure Washer Common Faults
If your Karcher pressure washer isn’t working as it should, there are a few common faults that you can check for. First, make sure that the machine is properly plugged in and that the power switch is turned on. If the machine still doesn’t start, check to see if the water supply is turned on and that there is enough water in the tank.
If there is no water coming out of the machine, there may be an issue with the pump or hose. Check to see if there are any kinks in the hose and if the pump is properly primed. If you’re still having trouble getting your pressure washer to work, contact a qualified technician for assistance.
Honda Pressure Washer Surging
If your Honda pressure washer is surging, there are a few possible causes. First, check the air filter to see if it is clean. If it is dirty, replace it with a new one.
Next, check the fuel mixture. The correct ratio is 50:1 (50 parts gas to 1 part oil). If the mixture is too rich or too lean, it can cause surging.
Finally, check the spark plug and make sure it is clean and properly gapped. If none of these solutions solve the problem, take your pressure washer to a qualified technician for further diagnosis and repair.
Pressure Washer Troubleshooting
If you’re having trouble with your pressure washer, there are a few things you can do to troubleshoot the issue. First, make sure that the unit is properly plugged in and that all connections are tight. Next, check the oil level and fill if necessary.
Finally, check the air filter and clean or replace it if needed. If these simple steps don’t solve the problem, then you may need to take your pressure washer to a service center for further diagnosis.
Pressure Washer Losing Pressure
If your pressure washer is losing pressure, there are a few things you can check to troubleshoot the issue. First, check the obvious things like the water supply and hose for any leaks. If everything looks tight, then it’s time to check the pump.
The most common reason for a pressure washer to lose pressure is because the pump isn’t working properly. There are a few things that can cause this, so you’ll need to do some diagnostics to figure out what exactly is wrong. First, check that the oil level in the pump is full.
If it’s low, add more and see if that fixes the problem. If not, then you’ll need to take a look at the seals and gaskets inside the pump itself. These can wear out over time and cause leaks, which will lead to loss of pressure.
Replacing them is usually pretty straightforward – just follow your manufacturer’s instructions.
If you’re still having trouble after checking all of these things, then it’s probably time to call in a professional or take your pressure washer to a repair shop.
Karcher Pressure Washer Cycles on And off
If your Karcher pressure washer is cycling on and off, there could be a few different reasons why. The most common reason is that the pressure washer’s pump is overheating. To fix this, you’ll need to give the pump a break by letting it cool down for 30 minutes.
Another possibility is that the water inlet filter is clogged. This can happen if you’re using water from a hose that hasn’t been used in awhile. To clean the filter, simply remove it and rinse it off with clean water.
Lastly, if your pressure washer has an unloader valve, it could be stuck in the “on” position. This will cause the pump to cycle on and off because it’s not able to build up enough pressure. To fix this, you’ll need to locate the unloader valve and turn it to the “off” position.

Why is My Pressure Washer Pulsating?
If your pressure washer is pulsating, it could be due to a few different factors. First, check to see if the pump is properly primed. If the pump isn’t primed, it can cause the pressure washer to pulsate.
Also, check the inlet water supply to ensure that it isn’t restricted or obstructed in any way. Another possible reason for pulsation could be an issue with the unloader valve. If there is something wrong with the unloader valve, it can cause pulsation as well.
Finally, make sure that all of the hoses and connections are secure and free of leaks. If any of these factors are causing your pressure washer to pulsate, you should be able to fix the problem relatively easily.
How Do I Stop My Pressure Washer from Pulsing?
If your pressure washer is pulsing, there are a few things you can check to troubleshoot the issue. First, check the water supply to ensure that it is turned on and that there is adequate water pressure. Next, check the pump to see if it is damaged or leaking.
Finally, check the hose for any kinks or blockages. If you cannot resolve the issue yourself, contact a qualified technician for assistance.
Why Does My Pressure Washer Surge When Trigger Released?
If your pressure washer is surging when the trigger is released, there are a few possible causes. The most common cause is that the pump isn’t primed properly. This can happen if you don’t fill the pump with enough water before turning it on, or if you run the pump dry (i.e. without any water).
Another possible cause of surging is that the unloader valve isn’t working properly. The unloader valve regulates the flow of water through the pump, and if it’s not working correctly, it can cause surging.
Finally, surging can also be caused by a problem with the regulator (if your pressure washer has one).
The regulator controls the amount of pressure that’s produced by the pump, and if it’s not set correctly, it can cause surging.
How Do I Fix My Pulsating Karcher Pressure Washer?
If your Karcher pressure washer is pulsating, it may be due to a blockage in the pump. To fix this, you will need to remove the blockage and clean the pump.
1. Disconnect the power supply to your pressure washer.
This will ensure that you do not damage the pump when cleaning it.
2. Remove the high-pressure hose from the pump. You may need a wrench to loosen the fittings.
3. Remove any debris or build-up from inside the pump using a brush or other tool. Be sure to clean all surfaces of the pump, including the impeller and housing.
4. Reassemble your pressure washer and test it out.
