Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the unit before inspecting the lid or hinge area.
- Inspect lid wiring: On models with wired lids, gently move the lid and observe if the error appears/disappears, indicating a broken wire in the hinge.
- Check for visible damage: Look for pinched or frayed wires where the lid attaches to the body.
- Reset and test: After a 10-minute unplug, plug back in and test a non-pressure mode. If F3 returns immediately, the sensor is likely defective.
- Service recommendation: Lid sensor replacement usually requires disassembling the lid and hinge, best done by a technician.
