If your Craftsman pressure washer has no pressure, the pump is the most likely cause. A worn or damaged pressure washer pump assembly can leave the motor running while the machine produces weak pressure, low pressure, or no water pressure at all. If the pump is more than a few years old and you use the pressure washer often, replacing the complete pump assembly is usually the most practical repair. A relatively new pump on a machine used only occasionally may need a rebuild instead, starting with the pump seals. Inspect the pump, pump head, manifold, valves, pistons or plungers, and o-rings for wear or damage before ordering parts. A failed pump assembly or worn seals can prevent the pump from building pressure even when water flows through the hose and spray gun. This guidance applies to Craftsman gas and electric pressure washers because both use a separate pump system, although the engine or electric motor may still run normally.
