How to Fix / Troubleshooting

Safety first: Unplug the cooker and ensure it is cool and depressurized.

  • Inspect sensor tube: Remove the lid and locate the small tube leading to the pressure sensor. Clean any blockages with warm water and a thin brush, then dry completely.
  • Check wiring: Remove the bottom cover and verify the pressure sensor connector is firmly attached to the main board.
  • Replace sensor: If the tube and wiring are intact but the error persists, replace the Cosori pressure sensor assembly.
  • Board diagnosis: Continued PrSE after sensor replacement suggests a main control board fault that should be addressed by a technician.
