There are many similarities and a few slight differences between Generac’s OneWash power washers, model numbers 6602 and 6413. Both of these units feature a spray gun, 20” lance with quick connect features, a 30 ft. high pressure hose, recoil starter, and choke mechanism. Moreover, both of these units feature a thermal relief valve, Power Dial, and drainable chemical tank; the thermal relief valve cycles water through the unit’s axial cam pump when water reaches 125°F, thereby preventing potential damage to the pump, and the Power Dial provides optimal cleaning power for each desired application. Each pump also comes with 3 different nozzles for optimal cleaning; the Blast (0°), Wash (25°), and detergent nozzles can be utilized for various high pressure cleaning applications. Both units also feature a constant flow rate of 2.8 GPM, and an oil capacity of 20 ounces. Also, both units operate between 2000 and 3100 psi.
The key difference between these two models IS that model number 6413 features a System Alert LED, which monitors the engine’s oil level and water supply pressure; while both feature a Low Water Shutdown, only model number 6413 has an LED warning depicting such a shutdown. The engine will shut down to protect the unit, and a fault indicator light will display on the control panel. Also, model number 6413 features a Low Oil Shutdown and associated alert, that of which is not featured on model number 6602.
