Why does my Generac Portable Products 1540-0 Pressure Washer pump have low pressure?
- HHeather AlexanderAug 9, 2025
If the Generac Portable Products Pressure Washer pump is failing to produce pressure, has erratic pressure, chatters, loses pressure, or has low water volume, several issues could be the cause. You may have a low-pressure nozzle installed, in which case you should replace it with a high-pressure nozzle. The water inlet might be blocked and needs clearing. Ensure an adequate water supply. Check for a kinked or leaking inlet hose, and straighten or patch it as needed. Inspect and clean the inlet hose strainer if it's clogged. The water supply should be cooler than 100°F. Clear any blockages in the high-pressure hose or replace the gun if it leaks. Clean the nozzle if obstructed. If none of these steps work, the pump may be faulty, and you should contact a Generac service facility.
