Understanding the Pressure Washer System

Before learning how to prime a Hotsy pressure washer, it is important to understand the different components of the pressure washer system. This knowledge will help you better understand the priming process and troubleshoot any potential issues that may arise.

Pressure Washer Pump

The heart of the pressure washer system is the pump. The pump is responsible for pressurizing the water in order to create the force needed for effective cleaning. Most Hotsy pressure washers use an axial piston pump that is powered by either an electric motor or a gasoline engine.

When the pump is running, it creates a suction effect that draws water from the water source or a detergent tank. This water is then pressurized and forced out of the spray nozzle at high velocity.

Unloader Valve

The pressure washer system also includes an unloader valve, which regulates the pressure generated by the pump. The unloader valve ensures that the pressure does not exceed the maximum rating of the pressure washer. It achieves this by diverting excess water back into the water source or recirculating it within the system.

In some pressure washers, the unloader valve is integrated into the pump. In others, it may be a separate component that can be adjusted to control the pressure output.

If the unloader valve is not functioning properly, it can cause issues with priming the pressure washer. It is important to check the unloader valve and ensure it is clean and properly adjusted.
