Possible Causes

Open or shorted lid sensor, Damaged sensor wiring in hinge, Failed sensor on lid PCB, Control board sensor input fault

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.
