How does a pressure washer work?

A pressure washer simply works by spraying water at high pressure. This is done by a motor that forces water through a small opening to increase pressure. The pressure exerted by a high-pressure washer can range from 100 to 500 bar depending on the model. With this power, a pressure washer can remove even the most stubborn stains, dirt and mud from surfaces.

Parts and accessories for your pressure washer

A high-pressure washer consists of various parts and accessories, including an engine, a pump, a hose, a spray gun and various nozzles. The spray gun has a trigger that controls the water flow, and the nozzles have different openings to control the water jet. Other accessories can include different types of hoses, detergents and extensions that allow you to clean more difficult to reach areas.

Why go for a high-pressure washer?

A pressure washer offers an efficient way to clean surfaces and can be used in a variety of situations. Whether you want to clean a terrace, driveway, car or even a swimming pool, a pressure washer is a handy tool to remove dirt and stains while saving time.

Common problems with pressure washers

Unfortunately, pressure washers can sometimes have certain problems. Here are some common problems and how to solve them.

Why doesn't my pressure washer build up pressure?

If your high-pressure washer does not build up pressure, it could mean there is a blockage in the hose or nozzle. Check these parts and clean them if necessary. It could also be that the pressure washer's pump is broken. In that case, replace the pump.

Why is my high-pressure cleaner not working?

If your pressure washer does not work at all, it could mean that the power supply is not connected properly or that the circuit breaker is off. Check the power supply and switch on the circuit breaker.

Why does my pressure washer stutter?

A common problem with pressure washers is that they can stutter during operation. This can have several causes, such as a clogged nozzle or a blocked supply line. But it can also be due to the pressure washer itself. If your pressure washer has an air intake, it may be clogged with dirt and dust. This can lead to disrupted airflow, causing the pressure washer to start stuttering.

So how do you solve this problem? First, it is important to make sure that you properly clean and check all parts of your pressure washer for blockages. But if the problem persists, you can also look into using accessories such as an air filter or a pressure washer with a water-cooled motor. These accessories help improve airflow and prevent your pressure washer from stuttering.

My pressure washer keeps turning on and off?

Another common problem with pressure washers is that they can suddenly turn on and off during use. This can have several causes, such as a clogged supply line, a worn or damaged pump, or an overheated motor. It can also be due to the pressure washer's electrical system, such as a broken switch or a bad connection.

How do you solve this problem? Firstly, it is important to ensure that all parts of your high-pressure washer are well maintained. Check the supply lines regularly for blockages and replace worn parts. If the problem persists, you can also look at parts such as a pressure regulator or thermal protector. These accessories help regulate the pressure and temperature of the pressure washer and prevent it from turning on and off during use.

Pressure washers are convenient devices for cleaning surfaces quickly and efficiently. But like any other appliance, they need regular maintenance and the necessary accessories to function optimally. Make sure you regularly check that all parts of your high-pressure washer are in good condition and make use of accessories to solve any problems.

Tip from our product specialist: Make sure your pressure washer is stored frost-free in winter. Water left behind can damage the device. Is frost-free storage not possible? Then at least make sure the pressure washer has no water left in the pipes.

Pressure washer leaking at the handle

A common problem with pressure washers is that they might start leaking at the handle. This can have various causes, such as a worn or damaged seal, a loose connection, or simply wear and tear from frequent use. This can be very annoying and prevent you from cleaning optimally.

How do I repair my leaking pressure washer?

To solve this problem, it is important to first determine where the leakage is coming from. If the problem is at the handle, it is best to check the seal first. Often this is worn out and needs to be replaced. You can do this yourself using a replacement seal, which you can get at most hardware stores.

If the seal is not the problem, you can also look at the connections around the handle. Make sure all connections are tight and not damaged. If this does not solve the problem, you can also consider buying a pressure washer with a metal handle. These are generally sturdier and more durable than plastic handles.

In short, pressure washer leaks at the handle can have several causes, but often the problem can be fixed by replacing the seal or checking the connections. If the problem persists, consider buying a pressure washer with a metal handle.

Can I use my high-pressure washer with hot water?

This is a frequently asked question, and the answer is not as simple as yes or no. Some pressure washers are designed to work with hot water, while others are not. It is important to check the manual of your pressure washer to see if it is suitable for use with hot water.

If your pressure washer is suitable for hot water, be cautious that the temperature is not too high. Too high a temperature can damage parts of the pressure washer, such as the seals. Therefore, always ensure that the temperature does not exceed the recommended temperature in the pressure washer's manual.

How do I repair my pressure washer?

If your pressure washer stops working properly, there are several ways to fix it. Here are some tips:

Descaling pressure washer: If you notice that your pressure washer is not as powerful as it used to be, it may have calcified. You can descale the pressure washer by using vinegar or a descaling agent.

Pressure washer parts: A part of the high-pressure washer may have broken and needs to be replaced. For example, you can buy new pressure washer parts at Fiyo.
