Possible Causes

How to Fix / Troubleshooting
Safety first: Verify the wall outlet with another device. Unplug the multicooker before any inspection. Mains voltages are dangerous.
Steps to diagnose:
- Check external factors: Confirm the outlet works and that any power strips or surge protectors are switched on and functional.
- Inspect the power cord: Look for cuts, kinks, or burn marks. Gently wiggle the cord at both ends while plugged in (if safe) to see if power flickers; if so, replace the cord.
- Check mains inlet: Ensure the cord is fully seated in the cooker (if detachable). Inspect for looseness or damage.
- Internal fuse (advanced): With the unit unplugged, remove the housing and locate the input fuse on the main PCB. Test for continuity; replace only with the same rating if blown, and investigate why it failed.
- Inspect power supply: Look for burnt components or bulging capacitors in the power supply area. If present, the main board will likely need replacement.
When to call a technician: If the fuse blows again or the power supply appears damaged, professional service is required.
