E5 appears during pressure or high-temperature programs; cooker stops heating and may beep continuously.

Safety first: For pressure-capable Redmond multicookers, never force the lid open while under pressure. Unplug the unit and allow pressure to drop naturally.

• Release pressure safely: Once the float valve drops, open the lid carefully away from your face.
• Clean steam valve: Remove the steam release valve and anti-block shield (if fitted). Wash thoroughly with warm soapy water to remove starch and grease. Ensure all holes are clear.
• Check safety valve: Inspect the safety valve in the lid for free movement. It should not be stuck with dried food. Clean and reassemble.
• Avoid overfilling: Do not fill above the MAX line, and avoid foamy foods (e.g., porridge, beans) without sufficient oil or anti-foam measures.
• Inspect pressure sensor: On some models, a pressure sensor is mounted in the lid or body. If E5 recurs after cleaning, the pressure sensor or control board may need professional diagnosis and replacement.
