In this guide, we’ll troubleshoot the most common causes of low pressure in pressure washers, so you can get your machine back up and running in no time.

We’ll start by discussing the basics of how a pressure washer works. Then, we’ll take a look at the different things that can go wrong and how to fix them. By the end of this guide, you’ll be able to diagnose and fix the problem with your pressure washer like a pro.

Reasons Why Low Pressure Siphon Not Working Pressure Washer

Dirty Filter

The most common cause of low pressure in a pressure washer is a dirty filter. The filter traps dirt and debris that can clog the pump and restrict water flow. To check the filter, remove it from the pump and clean it with a hose. If the filter is damaged, replace it with a new one.

Clogged Nozzle

Another common cause of low pressure is a clogged nozzle. The nozzle is the part of the pressure washer that directs the water stream. If the nozzle is clogged with dirt or debris, it will restrict water flow and cause low pressure. To clean the nozzle, remove it from the gun and soak it in a cup of vinegar for a few minutes. Then, rinse the nozzle with water and reattach it to the gun.

Blocked Intake

If the intake of the pressure washer is blocked, it will prevent water from flowing into the pump. This can cause low pressure or no pressure at all. To check the intake, remove the inlet hose from the pump and look for any obstructions. If there are any obstructions, remove them and reconnect the hose.

Damaged Pump

If the pump is damaged, it will not be able to generate enough pressure to power the pressure washer. This can cause low pressure or no pressure at all. To check the pump, remove the inlet hose from the pump and turn on the pressure washer. If the pump is making a loud noise or is not generating any pressure, it is likely damaged and will need to be replaced.

Low Voltage

If the pressure washer is not getting enough power, it will not be able to generate enough pressure. This can be caused by a loose connection, a faulty power cord, or a problem with the power outlet. To check the voltage, use a voltmeter to measure the voltage at the pressure washer’s power cord. If the voltage is below 110 volts, the pressure washer will not work properly.

Incorrect Water Pressure

If the water pressure at the pressure washer is too low, it will not be able to generate enough pressure. This can be caused by a problem with the water supply, such as a low water pressure or a restricted water flow. To check the water pressure, use a pressure gauge to measure the water pressure at the pressure washer’s inlet hose. If the water pressure is below 40 psi, the pressure washer will not work properly.

How to Troubleshoot: Low Pressure Siphon Not Working Pressure Washer

Symptoms of a Low Pressure Siphon Not Working Pressure Washer

There are a few symptoms that you can look for to determine if your pressure washer’s siphon is not working properly. These include:

Low water pressure: The most obvious symptom of a problem with your pressure washer’s siphon is low water pressure. If you’re not getting the desired amount of pressure from your pressure washer, it’s possible that the siphon is not working properly.

Water leaking from the pump: If you see water leaking from the pump on your pressure washer, it’s possible that the siphon is not working properly. This is because the siphon is responsible for drawing water from the pump and sending it to the nozzle. If the siphon is not working properly, water will leak from the pump instead of being sent to the nozzle.

The pressure washer won’t start: In some cases, a pressure washer that has a problem with its siphon may not start at all. This is because the siphon is responsible for priming the pump, and if the siphon is not working properly, the pump will not be able to prime.

Troubleshooting a Low Pressure Siphon Not Working Pressure Washer

If you’re experiencing any of the symptoms listed above, it’s likely that your pressure washer’s siphon is not working properly. To troubleshoot the problem, you can follow these steps:

1. Check the siphon hose:
The siphon hose is a small hose that connects the pump to the water inlet. If the hose is kinked or damaged, it can prevent water from flowing properly from the pump to the nozzle. Check the hose for any kinks or damage, and replace it if necessary.

2. Check the siphon cup:
The siphon cup is a small cup that sits inside the pump. It helps to create a vacuum that draws water from the pump and sends it to the nozzle. If the siphon cup is dirty or damaged, it can prevent water from flowing properly from the pump to the nozzle. Clean the siphon cup with a clean rag, and replace it if necessary.3. Check the siphon valve:
The siphon valve is a small valve that controls the flow of water from the pump to the nozzle. If the valve is stuck open or closed, it can prevent water from flowing properly from the pump to the nozzle. Clean the valve with a clean rag, and replace it if necessary.

Preventing Problems with Your Pressure Washer’s Siphon

You can help prevent problems with your pressure washer’s siphon by following these tips:

Keep the siphon hose free of kinks and damage:
Make sure that the siphon hose is not kinked or damaged. If the hose is kinked or damaged, it can prevent water from flowing properly from the pump to the nozzle.

Clean the siphon cup regularly:
The siphon cup can become dirty over time, which can prevent water from flowing properly from the pump to the nozzle. Clean the siphon cup with a clean rag on a regular basis.

Replace the siphon valve if necessary:
The siphon valve can wear out over time, which can prevent water from flowing properly from the pump to the nozzle. If you notice that the valve is sticking open or closed, replace it with a new valve.

By following these tips, you can help prevent problems with your pressure washer’s siphon and keep your pressure washer running smoothly.
