E8 error appears when trying to start a program; unit may beep repeatedly.

Safety first: Unplug the cooker before inspecting internal components.

• Verify inner pot is installed: Some Bella models will show E8 if the pot is missing. Insert the correct Bella inner pot and ensure it sits flat.
• Inspect pot bottom: Check for warping or dents. A significantly warped pot may not engage the detection mechanism properly and should be replaced.
• Clean the heating plate: Wipe the plate and the bottom of the pot to remove residue that could interfere with contact or weight sensing.
• Check pot detection mechanism: From the underside, locate any spring-loaded switch or weight sensor under the heating plate. Ensure it moves freely and is not stuck by debris.
• Replace detection switch if faulty: If the switch does not actuate when the pot is pressed down from above, the pot detection switch assembly may need replacement.
