If your pressure washer is surging, it’s likely due to a problem with the pump. The pump is what pressurizes the water in the washer, and if it’s not working properly, the washer will surge. There are a few things you can do to try to fix a surging pressure washer.
If your pressure washer is surging, it’s likely due to one of two issues: either the pump isn’t delivering enough water or there’s an issue with the unloader valve.
To fix a pump that isn’t delivering enough water, you’ll need to check the inlet screen and make sure it’s clear. If it is, then you may need to replace the pump.
If the problem is with the unloader valve, you’ll need to clean it and make sure that it’s free of debris. You may also need to adjust the spring tension.
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 unloader valve is stuck in the “on” position. If it is, simply turn it to the “off” position and see if that stops the surging.
If not, then the problem may be with your pump itself.
One common cause of a pressure washer pump surging is an air leak. To check for this, first make sure that all of the hoses and fittings are tight.
Then start the pressure washer and let it run for a few minutes without spraying anything. If you hear a hissing sound, that’s an indication of an air leak. The most likely culprit is a loose fitting or cracked hose.
Once you find the source of the leak, tighten or replace as necessary.
Another possible cause of pump surging is dirty or old oil in the crankcase. If your pressure washer has been sitting for awhile without being used, chances are good that the oil has degraded and needs to be replaced.
Simply draining and refilling with fresh oil should fix the problem.
Pressure Washer Surging/Pulsing
If your pressure washer is surging or pulsing, it’s likely due to one of two issues: either the pump isn’t getting enough water or there’s something blocking the flow of water. If you’re having this problem, here are a few things you can try:
First, check that the hose connecting your pressure washer to the water supply is turned on all the way.
If it’s not, turn it on and see if that solves the problem.
If the hose is turned on but your pressure washer is still surging or pulsing, there may be something blocking the flow of water. Check the inlet screen (where the water goes into the pressure washer) and make sure there’s no debris clogging it up.
Also check the outlet screen (where the water comes out of the pressure washer) and clean any debris out of that as well.
If you’ve checked both screens and there doesn’t seem to be anything blocking them, it’s possible that your pump isn’t getting enough water. This can happen if the hose isn’t big enough or if there’s not enough water pressure coming from your faucet/hose connection.
Try using a different hose or increasing the water pressure at your faucet and see if that solves the problem.
Karcher Pressure Washer Surging/Pulsing
If your Karcher pressure washer is surging or pulsing, it’s likely due to one of two issues. Either the pump isn’t getting enough water or there’s an issue with the unloader valve. Let’s take a closer look at each issue and how you can fix it.
If the pump isn’t getting enough water, it will start to surge or pulse. This is because the pump is designed to run on a continuous flow of water. When the flow of water is interrupted, the pump will start to cavitate, which causes it to surge or pulse.
To fix this issue, you need to make sure that the hose from the pressure washer to the faucet is not kinked or blocked in any way. You also need to ensure that there’s no leaks in either the hose or fittings. Once you’ve done that, turn on the water and let it run for a few minutes before starting your pressure washer.
If your pressure washer has an adjustable unloader valve, it may be set too high. This can cause surging and pulsing as well because it interrupts the flow of water through the pump. To adjust the unloader valve, turn clockwise to decrease pressure and counterclockwise to increase pressure.
Electric Pressure Washer Surging
If your pressure washer is surging, it’s likely due to one of two things: either the pump isn’t primed properly, or there’s an issue with the unloader valve. If you’re having trouble with your pressure washer surging, here are a few tips to help you get to the bottom of the problem.
First, check that the pump is properly primed.
This can be done by opening the bleed valve and running water through the pump for a few minutes. If this doesn’t fix the problem, then it’s likely that there’s an issue with the unloader valve.
To check the unloader valve, first make sure that there’s no debris or blockages in the line.
Next, remove the hose from the outlet side of the valve and check that the plunger moves freely. If it doesn’t move freely, then it may be stuck in place and will need to be replaced.
Once you’ve checked both of these things and still can’t get your pressure washer to stop surging, then it’s time to call in a professional for help.
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’s clean. If it’s dirty, replace it with a new one.
Next, check the spark plug to see if it needs to be replaced. Finally, check the fuel line to see if it’s clogged. If none of these solutions solve the problem, take your pressure washer to a qualified technician for further diagnosis and repair.
Pressure Washer Throttle Problems
If you’re having pressure washer throttle problems, there are a few things you can check. First, make sure the throttle is in the correct position. Next, check the fuel line and make sure it’s not kinked or blocked.
Finally, check the air filter and spark plug to make sure they’re clean. If all of these things check out, then it’s likely that your pressure washer needs to be serviced by a professional.
Ryobi Pressure Washer Surging
If your Ryobi pressure washer is surging, there are several possible causes. First, check the intake filter to see if it is clogged. If the filter is clean, then the problem may be with the pump itself.
Try cleaning the pump by removing any debris that may have accumulated on it. If the pump is still not working properly, you may need to replace it.
Troy Bilt Pressure Washer Surging
If your Troy-Bilt pressure washer is surging, it may be due to a number of different factors. First, check the oil level in the pump. If the oil level is low, add oil until it reaches the full mark on the dipstick.
Next, check for any blockages in the intake screen or hose. If there are any blockages, clean them out and try again. Finally, check the unloader valve to make sure it is not stuck in the “on” position.

Why Does My Power Washer Keep Surging?
If your power washer is surging, it could be caused by a few different things. First, check to see if the engine is running at a consistent speed. If the engine speed is fluctuating, it could be causing the pump to surge.
Second, check the pressure relief valve to make sure it’s not stuck in the open position. A stuck pressure relief valve can cause water to flow back into the pump, causing it to surge. Finally, check the unloader valve to make sure it’s functioning properly.
An improperly functioning unloader valve can also cause surging.
Why Does My Pressure Washer Rev Up And Down?
If your pressure washer is revving up and down, it’s likely that the engine is being overloaded. This can happen if there’s too much debris in the water, or if the pump isn’t primed correctly. To fix this, first check the intake screen to make sure it’s clear.
Then, prime the pump by running water through it for a few minutes without turning on the power washer. If neither of these fixes works, you may need to get a new pump.
How Do I Stop My Pressure Washer from Pulsating?
If your pressure washer is pulsating, it could be because the pump isn’t primed properly. To prime the pump, start by making sure there’s fresh oil in it. Then, turn on the water supply and hold down the trigger until water starts flowing from the nozzle.
Once water starts flowing, release the trigger and let the pump build up pressure.
If your pressure washer is still pulsating after priming the pump, it could be because of a restricted intake filter. Check the filter to see if it’s clogged with dirt or debris.
If so, clean or replace it as needed. You should also check for any kinks in the hose that could be restricting water flow.
How Do You Bleed Air from a Pressure Washer?
If your pressure washer isn’t performing as it should, one possible issue is that there is air in the pump. This can happen if you store your pressure washer for an extended period of time without using it. Over time, the seals in the pump can dry out and allow air to enter.
Bleeding the air from your pressure washer’s pump is a relatively simple process that anyone can do.
To bleed air from your pressure washer’s pump, start by turning off the engine and disconnecting the spark plug wire so that the engine can’t accidentally start while you’re working on it. Next, locate the bleeder valve on the side of the pump.
The location of this valve will vary depending on make and model, so consult your owner’s manual if you’re unsure where to find it. Once you’ve located the valve, open it up and attach a length of clear tubing to it. Run the other end of the tubing into a container such as a bucket or jar.
Now start up your pressure washer and let it run until all of the air has been purged from the system and only water is coming out of the tubing into your container. Once this happens, close up the bleeder valve and reattach any covers or hoses that may have been removed during bleeding process. Your pressure washer should now be primed and ready to use!
