Hart Pressure washer has no pressure

If your Hart pressure washer has no pressure, the pump assembly is the most likely problem. A worn or damaged pump may cause a pressure washer to have no pressure, run at low pressure, or stop building pressure even though the motor runs. When the pump is more than a few years old and the machine is used often, replacing the complete pressure washer pump assembly is usually the best repair. If the pump is relatively new or the pressure washer is used only occasionally, the pump may be repairable by rebuilding it or replacing the pump seals. Damaged pump components, including the pump head, pump manifold, pump pistons, pump valves, or pump o-rings, can also reduce water pressure. Make sure the replacement pump matches your Hart pressure washer before ordering. Enter your model number to find the exact pump assembly, pump, or seal kit made for your specific machine. With the correct part and a few basic tools, you can restore pressure without replacing the entire pressure washer.
