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.
