Sterra Flow — E5 NTC Short Circuit — LED Flashes Red Green BlueUpdated a day ago
If your Sterra Flow digital display screen is flashing the E5 error code and the indicator lights are cycling through a combination of Red, Green, and Blue, please be completely reassured. Your vacuum has not suffered a critical meltdown or permanent damage!
An E5 code indicates that the vacuum's microprocessors have triggered a Smart Thermal Sensor Guard. The Sterra Flow battery pack is equipped with a highly specialized sensor called an NTC thermistor, which constantly reads the internal temperature of the lithium-ion cells down to the exact degree to ensure safe operation. If this sensor experiences a communication lag or an electrical calibration glitch, the vacuum instantly pauses all operations as a standard safety precaution to protect the battery pack's integrity.
🛑 Immediate Safety Step: To allow the smart safety system to rest, please turn off the vacuum, remove the battery pack from the main handle slot, and disconnect any charging cables. Leaving the unit fully powered down gives the internal components the optimal environment to stabilize.
