Multicooker shows E5 and will not build pressure or complete pressure-cook programs.

Safety first: Unplug the unit and ensure all pressure is released before removing the lid. Never attempt to service the pressure system while the cooker is pressurized.

• Clean pressure sensor port: On many KitchenAid multicookers, the pressure sensor is connected to a small port or tube from the lid or lid ring. Check for dried food or starch blocking the port and clean with a soft brush or toothpick (do not enlarge the hole).
• Inspect sensor wiring: If accessible under the top cover, verify that the pressure sensor connector is firmly attached to the control board and that wires are not pinched or broken.
• Check sealing components: Ensure the lid gasket, float valve, and steam release valve are clean and correctly installed. Poor sealing can prevent pressure from building, which may be interpreted as a sensor fault.
• Test with water only: Add 2–3 cups of water, close the lid, and run a short pressure program. If E5 appears again and no pressure builds, the sensor or board likely needs replacement.
• When to call a technician: Pressure sensor replacement and board diagnostics should be performed by a qualified technician due to safety-critical nature.
