When your Briggs & Stratton pressure washer has no pressure, the pump assembly is the most likely problem. A worn or damaged pump can cause a pressure washer not building pressure, low pressure, or a motor that runs but produces no pressure. If the pump is more than a few years old and the machine is used often, replacing the pump assembly is usually the best repair. If the pump is relatively new or the pressure washer is used only occasionally, rebuild the pump or replace its pump seals instead. Worn pump seals can allow internal pressure to escape, while damaged pump pistons, plungers, valves, or o-rings can also prevent the pump from working correctly. Before ordering parts, confirm that the water supply is turned on and the inlet screen is clear, since restricted water flow can contribute to weak pressure.

You may need to rebuild or replace the pump. If the pump is more than a few years old, and you use the pressure washer fairly often, replace the pump. If the pump is relatively new, and you don’t use the pressure washer often, either rebuild the pump or replace the pump seals.
