The first step in fixing a pulsing pressure washer is to identify the source of the problem. Inspect the intake and outlet hoses to make sure they are tightly connected and there are no blockages. In some cases, a clog in the hose can cause the pressure washer to pulse.
Make sure the hose is free of obstructions before proceeding to the next step.
Next, check the pump for any issues such as loose parts or worn seals. If the pump has been damaged, it may need to be repaired or replaced. Replace any worn seals or worn valves to ensure the pump is working properly.
If the pump is functioning correctly, the next step is to inspect the unloader valve. This valve is responsible for regulating the pressure of the washer and, if it is damaged or stuck, it can cause the washer to pulse.
Make sure the valve isn’t stuck and is working correctly.
Lastly, check the bypass valve to ensure it is operating correctly. This valve is responsible for allowing excess water to be released and, if it isn’t set correctly, it can cause the pressure washer to pulse.
Once the valve is set correctly and all the other components are in working order, the pressure washer should run smoothly.
Why is my pressure washer revving up and down?
One possibility is that there may be air trapped in the pump, which can cause the motor to labor and stall when it comes on. To make sure this isn’t the issue, check the pump and make sure it’s full of oil and there are no air pockets.
Another potential cause could be an issue with the spray gun. If the spray nozzle is clogged or blocked, the engine may rev up and down trying to build up pressure. Your solution is to clean the nozzle and ensure that it is not obstructed.
Finally, there may be something wrong with the fuel or spark plug. Check the spark plug and make sure it is connected properly, and then check the fuel filter for any signs of blockage or accumulation.
If none of these steps helps fix the problem, it may be best to take it to a professional pressure washer repair service.
Why does my pressure washer keep losing pressure?
There are several possible reasons why your pressure washer may be losing pressure.
First, the pump may need to be serviced. Pressure washers rely on the pressure washer pump to create the pressure you need for cleaning. Over time, the pump can become damaged or dirty, resulting in lower pressure.
A service technician can inspect and clean the pump to restore the proper pressure.
Second, the inlet filter could be blocked. A blocked filter will reduce the pressure of the pressure washer. A dirty or clogged filter should be replaced at least once a year.
Third, the hose may be leaking. Leaking hoses can introduce small amounts of air, reducing the pressure output. Inspecting the hose for damage and replacing any worn or cracked hoses can resolve this issue.
Finally, an issue with the hose gun could be causing the pressure to decrease. The hose gun is where the unloader valve is located, which controls how much water is being supplied to the pressure washer.
Your local service technician can inspect the hose gun and unloader valve to ensure it is in proper working order.
If you are still having issues with your pressure washer losing pressure, it is best to have it serviced by an experienced service technician. They can inspect and diagnose any underlying issues causing the decreased pressure.
What is the most common problem with pressure washers?

If your pressure washer is leaking, it’s important to troubleshoot the problem right away as continued use can cause further damage to the pump and other components. Additionally, over-pressurizing the washer can cause leaks in the hose and connections, so it’s important to make sure that you are using the correct pressure for the job.
If you are still having trouble resolving the issue, it’s best to take the pressure washer to a repair service for professional help.
How long can you continuously run a pressure washer?
The length of time a pressure washer can be safely and effectively run continuously will depend on what kind of pressure washer it is and its design. For example, electric pressure washers tend to have shorter run times as they require a consistent power source and the motor starts to overheat if it runs for too long of a period.
Gas-powered pressure washers may be able to run for long periods since they are not reliant on a power source, however the engine may overheat if it runs for too long, and the pump may wear out if run continuously.
Proper maintenance and keeping an eye on the engines temperature is important so it doesn’t overheat. Generally, a pressure washer should not be run continuously for more than 30-45 minutes. If continuous use is necessary, it’s best to let the pressure washer cool down in between uses.
Do you turn water on before starting pressure washer?
Yes, it is important to turn the water on before starting your pressure washer. Turning the water on first allows the pressure washer’s pump to fill with water before the motor is running. This will make sure the pump is lubricated and functioning correctly.
Additionally, make sure that the water pressure is above the minimum requirement for the pressure washer to operate properly and avoid damage to the machine. Additionally, you should always check your owner’s manual for specific instructions on how much pressure the washer should have to avoid overpressurizing it.
Lastly, check that the hoses, nozzles, and connections are all tight and secure, and that the garden hose is long enough to reach the area that you are trying to clean.
How do you know if your unloader valve is bad?
You can generally tell if your unloader valve is bad if the pressure in your line drops unexpectedly or if your equipment struggles to start up or stops running normally. You might also hear sudden bursts of air, the line pressure will not stay consistent, and the system may lose capacity or power.
Additionally, if the valve does not adjust pressures appropriately when the pump starts or stops, or fails to open or close, this is another indication that your unloader valve might be bad.
If you are still unsure, you can also test your unloader valve with a pressure gauge by measuring the pressure in the line before and after the unloader valve and seeing if they match up. If the pressures are off, the unloader valve may not be working correctly and needs to be checked or replaced.
Why wont my pressure washer shut off?
If your pressure washer is not shutting off, there are several possible causes.
The most common cause is the pressure switch or trigger becoming stuck in the on position. This can happen if the machine has been pushed too hard, leading to the heat and pressure building up in the pump.
If this happens, the pressure switch can become stuck, and the machine will not be able to turn off.
Another possible cause is some kind of mechanical defect. If a crucial part of the switch is broken or worn out, the machine will struggle to turn off. This could be caused by a worn out bearing, shaft, or other part of the switch.
You can also check the electrical connections, especially if the machine has been exposed to water or moisture. If the connections have become corroded, this could mean the switch is not getting the right power or is not being told when to turn off.
Finally, if the problem persists, it is best to call a qualified technician to inspect the pressure washer and make any necessary repairs.
Where is the unloader valve on an electric pressure washer?
The unloader valve on an electric pressure washer is typically located on the pump head. It is usually a small, inline valve with a ball valve attached. On some models, the unloader valve may be located in the hose or nozzle.
To locate the unloader valve, turn off power to the pressure washer and disconnect the water supply. Remove the inlet filter and the pressure relief valve, then look for the valve along the pressure line.
It may be necessary to remove access plugs and cover panels to view the unloader valve. In some cases, you may also need to remove the pump head to access the valve. Once you have located the unloader valve, you can adjust it per the manufacturer’s instructions.
Where is unloader valve located?
The unloader valve is typically located near the compressor and is connected to the pressure relief valve. It is the component which controls the air pressure inside the compressor, allowing air to be discharged from the tank when the tank reaches a certain pressure.
The unloader valve is typically a ballcock type valve and is adjustable to determine the air pressure level at which it will engage and release air from the tank. It is important to note that the pressure relief valve should always be set higher than the unloader valve, as the pressure relief valve is there to protect the compressor and downstream components from damage in the event of an overpressure situation.
Why does my pressure washer shut off when I pull the trigger?
Your pressure washer shuts off when you pull the trigger because it has a safety feature called an Unloader Valve. This is a device that is located near the pump and regulates the pressure by releasing any excess pressure in the pump.
When the trigger is pulled, the Unloader Valve releases the pressure and the engine will shut down. This is a safety feature to protect the user and prevent damage to the pressure washer. If the Unloader Valve gets clogged or blocked, it can cause the engine to shut down when the trigger is pulled even if the pressure is not too high.
To resolve this issue, the Unloader Valve should be checked for clogs and cleaned regularly.
