How to Fix / Troubleshooting
Safety first: Unplug the multicooker and let it cool. Do not attempt to remove the lid hinge while the unit is hot.
- Inspect lid cable (if visible): Some Brock models have a visible cable or harness running through the lid hinge. Check for pinched, cut, or frayed insulation.
- Clean lid interior: Remove the inner lid plate (if removable) and clean any condensation, oil, or food residue around the sensor area. Dry thoroughly.
- Check for moisture: Excess steam condensation inside the lid can temporarily affect the sensor. Leave the lid open to dry for several hours and then test again.
- Test non-pressure modes: Try a low-temperature mode like KEEP WARM or YOGURT. If E8 appears immediately, the lid sensor circuit is likely defective.
- Service note: Lid sensor replacement usually requires disassembling the lid and hinge. This should be done by a qualified technician to avoid damaging the steam path or hinge mechanism.
