Possible Causes
Weak household circuit or shared high-load devices, Loose mains cord connection inside cooker, Failing capacitors in main PCB power supply, Partial short in heater wiring
How to Fix / Troubleshooting
Safety: Unplug before internal inspection.
- 1. Dedicated outlet: Plug the multicooker into a dedicated wall outlet with no other high-wattage appliances.
- 2. Inspect power cord and strain relief: Ensure the cord is firmly anchored and that internal connections to the PCB are tight.
- 3. PCB inspection: Check the main PCB for bulging or leaking electrolytic capacitors in the low-voltage supply section. Replace the PCB if components are failing.
- 4. Heater wiring: Inspect heater wires for partial shorts to chassis or melted insulation.
Do not continue using the cooker if it repeatedly resets; this can corrupt internal memory.
