It is crucial to always ensure that there is an adequate water supply before starting a pressure washer. This simple step can prevent expensive repairs and extend the lifespan of your machine.

Importance of Water for Starting Pressure Washer

When starting a pressure washer, it is of utmost importance to have water present before starting the machine. Not having water in the pressure washer can lead to serious damage to the pump and other components of the machine.

The water in the pressure washer helps to cool down the pump and prevent it from overheating while in operation. Without water, the pump can quickly overheat, causing damage to the seals, pistons, and other internal parts. This can be an expensive repair and may even require replacing the entire pump.

Water also acts as a lubricant for the pump, helping the pistons move smoothly and preventing any friction or wear. Without water, the pump may seize up or experience excessive wear, leading to reduced performance and potentially costing more money for repairs.

In addition to protecting the pump, water also plays a crucial role in producing the high-pressure spray that a pressure washer is known for. Without water, the pressure washer will not be able to generate the necessary pressure to effectively clean surfaces. This means that even if the machine starts correctly without water, it will be useless for its intended purpose.

3. Hose Damage: The high-pressure hose plays a crucial role in delivering water to the nozzle. When the pressure washer is started without water, the hose can burst due to the buildup of excessive pressure. This not only poses a risk to the user but can also cause damage to surrounding objects or property.

4. User Safety: Starting a pressure washer without water can be dangerous for the user. Without water flowing through the system, the pressure washer can have sudden bursts of pressure when the trigger is pulled, leading to a loss of control and potential injury to the user or bystanders.

5. Motor Burnout: In some pressure washers, the motor is designed to shut off automatically when there is no water flow. However, if the pressure washer does not have this safety feature, running it without water can cause the motor to overheat and burn out.

It is essential to always connect a pressure washer to a water source before starting it. This not only protects the pressure washer from potential damage but also ensures the safety of the user and those nearby.

Impact on the Pump and Engine

Starting a pressure washer without water can have a detrimental impact on both the pump and the engine. The pump is designed to circulate water through the system, and without water, the pump can overheat and become damaged.

When there is no water running through the pump, it can create a condition called cavitation. Cavitation occurs when air bubbles form in the pump due to the lack of water. These air bubbles can then collapse, causing small implosions that can damage the internal components of the pump, including the seals, valves, and pistons.

Additionally, running the pressure washer without water can cause the pump to lose prime. The prime is the initial suction required to begin pumping water. Without water, the pump may not be able to establish this suction, leading to a loss of efficiency and possible damage.

Furthermore, the engine can be negatively affected by starting the pressure washer without water. Without the load of water passing through the system, the engine can experience what is known as “run dry.” This means that the engine is running without any resistance, causing it to rev at a higher RPM than intended. This excessive speed can lead to engine damage and premature wear.

In conclusion, it is important to always ensure that there is water running through the pressure washer before starting it. Failing to do so can result in damage to both the pump and engine, leading to costly repairs and a shortened lifespan of the machine.
