When it comes to the operation of a pressure washer, two key components work together to provide the necessary power and performance: the pressure washer pump and the engine. Understanding the relationship between these two components can help diagnose and troubleshoot any starting issues that may arise.

The Pressure Washer Pump: Powering the Cleaning Process

The pressure washer pump is responsible for the high-pressure water output essential for effective cleaning. It draws water from a water source, such as a hose or a tank, and pressurizes it to the desired level. This pressurized water is then expelled through the nozzle, delivering a powerful stream that can remove dirt, grime, and stains.

The pump is typically powered by the engine, either directly or through a belt or gear system. It relies on the engine’s rotation to generate the pressure needed for cleaning. Therefore, any issues with the pump, such as a malfunctioning valve or a clogged inlet, can impact the engine’s ability to start and run smoothly.

The Engine: Providing the Power to Drive the Pump
