How to Fix / Troubleshooting
Safety first: Unplug and let the unit cool before opening the base.
- Normal vs abnormal: Occasional soft clicks from relays and metal expansion are normal. Very loud or grinding noises are not.
- Check pot and plate: Ensure the inner pot sits flat and does not rock. Replace if warped.
- Inspect mounting screws: Remove the bottom cover and gently tighten the screws securing the heater plate and internal frame. Do not overtighten.
- Look for loose parts: Shake the cooled unit gently and listen for rattling. Secure any loose brackets or shields.
If noises persist and are accompanied by error codes or heating issues, seek professional inspection.
