What damages a power washer?

Since you now know how long a power washer lasts you might be wondering what causes the power washer to get damaged. 

Knowing this might help you prevent your precious machine from getting damaged. So, let’s look at the factors, shall we?

Bubble formation in water

The formation of bubbles in water inside the power washer is known as cavitation. This is one of the most common ways a power washer gets damaged.

There are mainly 2 factors that make their contribution to bubble formation.

One factor is the low water supply rate. Another problem occurs when the diameter of the hose is too small.

You see, each power washer has a specific demand for water supply. And if it’s lower than the minimum requirement it puts a strain on the machine.

Thus, over time the washer loses its capacity to work.

So, to solve this problem you can take a measured bucket and fill it with water from the power washer. Then use a clock to measure the time it takes to fill the bucket. 

Afterwards, simply divide the bucket’s capacity by the number of minutes it took to fill it up. You’ll then have your rate of water supply.

As for the next problem, which is the diameter of the garden hose, simply change it to suit the power washer.

Otherwise, the narrow hose will coggle up and block the water supply once and for all.

Thermal damage

Another factor that might damage your power washer is overheating. Yes, it might be shocking because power washers are designed to handle high pressure.

So, why can’t these heavy machines overcome overheating?

The thing is people assume that a machine that deals with high pressure is prone to heat as well. Although they are to some extent, extra thermal power can still deteriorate them.

This excess heat is produced when the trigger of the power washer is released by turning off the machine first. 

The high pressured water cannot escape from the hose and they end up creating the excess heat.

The best solution is to turn off the machine before letting go of the trigger. This will ensure your power washer has a long and healthy life.

The unloader valve setting

Lastly, we’ll focus on the unloader valve and how it damages your power washer.

You see, the unloader valve is responsible for ensuring that the water travels to the pump when the washer is not being used.

So, if they’re not properly installed the water will flow to the wrong places and your entire washer will get messed up.
