Error codes and troubleshooting
| Code | Meaning | What to do | Manual page |
|---|---|---|---|
| Overload | Generator was overloaded by too much drawn wattage. The overload reset button activates and cuts output within 3 to 16 seconds, depending on load. | Turn off and disconnect electrical devices until the overload light turns off. Wait about five minutes, then press the activated reset button. If no power after reset, turn off and disconnect all devices and restart the generator. | 23 |
| Flashes 1x | Voltage at the alternator is too low. There is no electrical output. | Check for loose connections. Call 1-800-232-1195 for assistance. Call service if it persists. | 24 |
| Flashes 2x | Engine speed is too low. There is no electrical output. | Check carburetor and stepper motor. Ensure Eco-Mode is OFF. Have the generator serviced; call 1-800-232-1195 for assistance. Call service if it persists. | 24 |
| Flashes 3x | Inverter temperature is too high. There is no electrical output. | Turn the generator off and let it cool fully for 1 to 2 hours before restarting. | 24 |
| Flashes 5x | Voltage at the alternator is too high. There is no electrical output. | Have the generator serviced; call 1-800-232-1195 for assistance. Call service if it persists. | 24 |
| Flashes 6x | Generator exceeded rated output and cut off power to protect itself. There is no electrical output. | Turn OFF and disconnect loads. Press the RESET button on the panel. Reduce the load on the generator. | 24 |

FAQ
How long does the WEN DF875iX run on a tank?
The maker rates it at 6.7 hours at 50 % load (about 3,500 W) on a 4.2-gal tank. A light load such as a refrigerator and lights runs longer; a full load runs shorter.
Can the WEN DF875iX start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 8750 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
