How to Fix / Troubleshooting
Safety first: Unplug immediately if you smell burning or see smoke. Do not continue using the appliance.
- External check: Inspect the power cord and plug for damage or overheating. Do not use if the cord is frayed or burnt.
- Internal inspection (advanced): Remove the outer casing to access the main PCB. Look for bulging capacitors, burnt tracks, or discolored components.
- Do not attempt board-level repair unless qualified: In most cases, the entire main control PCB should be replaced rather than repairing individual components.
- Reassembly: If no obvious damage is found but E9 persists, discontinue use and arrange for board replacement by a professional.
