E13 appears at the end of a pressure program; cooker does not switch to Keep Warm.

Safety first: Ensure all pressure is released before opening the lid. Keep clear of steam vents.

Step-by-step checks:

• 1. Check valve position: Confirm the steam release valve is in the correct position during cooking and that it moves freely between Sealing and Venting.
• 2. Inspect sealing ring: Remove and inspect the silicone sealing ring. Replace if stretched, cracked, or hardened.
• 3. Examine safety valve: Check for continuous steam leakage from the safety valve during cooking. If it leaks, replace the valve.
• 4. Clean lid components: Clean the anti-block shield, valve seat, and lid channels thoroughly to ensure proper sealing and controlled exhaust.
• 5. Sensor check (advanced): If mechanical parts are fine, the pressure sensor may not be detecting the pressure profile correctly, causing a timeout. Inspect its wiring and connector.

Note: Persistent E13 after mechanical maintenance may require replacement of the pressure sensor module.
