Daewoo Refrigerator Error Code Eg

The Eg error code on a Daewoo refrigerator indicates a water supply error detected through the I-Sensor (ice maker temperature sensor). Specifically, after a water fill cycle, the I-Sensor is expected to register a temperature rise caused by the warmer incoming water. If that temperature increase does not occur or does not reach the anticipated threshold, the control board registers a water supply failure. This points to a breakdown somewhere in the water delivery path to the ice maker, whether in the inlet valve, the water line, or the sensor itself.

The refrigerator's control logic is built to tolerate occasional anomalies. A single occurrence of this condition does not immediately halt ice production. Instead, the system monitors for repeated failures: if the error condition is detected three consecutive times, ice making is automatically paused. If normal water supply behavior resumes and the I-Sensor detects the expected temperature response, the error clears itself without requiring manual intervention. This self-correcting design helps prevent false shutdowns from brief, temporary supply interruptions.

Common root causes include a kinked or frozen water supply line, a failed or partially clogged water inlet valve that restricts flow, or an I-Sensor that has drifted out of calibration and cannot accurately detect temperature changes from incoming water. Low household water pressure can also prevent the fill valve from delivering adequate water volume, resulting in no measurable temperature shift at the sensor. Inspecting water flow, inlet valve operation, and sensor continuity are the primary diagnostic starting points.
