E5 error appears when trying to start a pressure program; cooker may not build pressure.

Safety first: Unplug the cooker and ensure it is cool enough to handle.

• Check steam release valve: Verify the valve handle is in the Seal position according to the Midea model markings. Clean the valve cap and ensure it moves freely.
• Inspect sealing ring: Remove the inner lid and silicone sealing ring. Wash with warm soapy water, rinse, and dry. Check for cracks, stretching, or hardening. Reinstall firmly in the groove.
• Clean lid and rim: Wipe the stainless steel rim of the cooker body and the lid contact surface to remove food residue or starch that can prevent sealing.
• Test again: Add water to the minimum line, close the lid, set to Seal, and run a pressure program. If E5 still appears, the pressure sensor calibration or lid locking mechanism may be faulty.
