Possible Causes
Loose AC inlet connection, Damaged power cord, Weak solder joints on power input of PCB, Unstable mains voltage
How to Fix / Troubleshooting
Safety first: Unplug the cooker before inspection.
- Check outlet and plug: Test the wall outlet with another appliance. Inspect the Daewoo plug for looseness or heat discoloration.
- Inspect power cord: Flex the cord gently along its length; if you feel kinks or see cracks, replace the cord.
- Check internal AC connections: Remove the bottom cover and verify that the power cord strain relief is secure and the live/neutral wires are firmly screwed or crimped to the PCB or terminal block.
- Look for heat damage: Examine the area around the AC input on the PCB for darkened spots or cracked solder joints; reflowing or board replacement may be needed.
If E15 continues after securing all connections and verifying stable mains power, the main PCB's power section may be failing and should be replaced.
