Possible Causes
Open-circuit main heating element, Shorted or open triac on control PCB, Burned solder joints on heater terminals, Overheated power relay (if used)
How to Fix / Troubleshooting
Safety first: Unplug the appliance. Do not attempt to run it again until basic checks are done.
- Visual inspection: Look under the unit (without opening the case) for signs of burning, melted plastic, or strong burnt smell, which indicate internal damage.
- Check mains outlet: Test the wall socket with another appliance to rule out supply issues.
- Avoid repeated resets: Do not repeatedly power-cycle the cooker if E6 appears; this can worsen internal damage.
- Service required: The heating circuit involves high voltage and power semiconductors. Diagnosis requires opening the base and testing the heater and triac/relay with a meter.
Due to shock and fire risk, this repair should be carried out only by a qualified technician.
