Why does my Craftsman 580.754882 Pressure Washer pump have low pressure?
- CCheryl MannAug 11, 2025
Several factors can cause low pressure in your Craftsman Pressure Washer pump. It could be due to a low-pressure selector nozzle being installed—try replacing it with a high-pressure nozzle. Other causes include a blocked water inlet (clear it), inadequate water supply (provide adequate flow), a kinked or leaking inlet hose (straighten or patch it), a clogged inlet hose screen (check and clean it), water supply exceeding 100°F (use cooler water), a blocked or leaking high-pressure hose (clear any blockages), a leaking spray gun (replace it), or an obstructed selector nozzle (clean it).
