A pressure washer is designed to work with water, and it will not start or function properly without water flowing through the system. Without water, the pump will not have anything to pressurize and the pressure washer will not produce any pressure. Also, the pump could be damaged if it runs without water, as it can cause friction and heat to build up, leading to overheating and possible damage to the pump.

It’s important to ensure that the water supply is turned on and the water inlet and hoses are properly connected before starting the pressure washer. Also, make sure the water pressure is adequate and the water flow is not obstructed. If the pressure washer is not getting water, it’s important to check for any leaks or blockages in the hoses or connections.

It’s important to follow the manufacturer’s instructions when using a pressure washer, and if the problem persist, it’s recommended to contact a professional or consult the manufacturer’s manual for assistance.
