E6 displays and the cooker stops heating or will not start; may occur when switching between modes or after a power surge.

Safety first: Disconnect the multicooker from power for several minutes before attempting any reset.

• Perform a power reset: Unplug the unit for at least 10 minutes to allow internal capacitors to discharge. Plug back in and check if the error clears.
• Check the outlet: Plug the cooker into a different, properly grounded outlet without extension cords or power strips. Unstable power can trigger control errors.
• Inspect control panel connections (advanced): With the unit unplugged, remove the top or front panel to access the control PCB and display board. Ensure any ribbon cables or plug-in connectors are fully seated and not damaged.
• Look for visible board damage: Examine the PCB for burn marks, bulging components, or corrosion. Any such signs usually indicate the board must be replaced.
• Reassemble and test: After reseating connectors, reassemble the housing and test basic functions. If E6 persists, the control board is likely faulty.

Warning: Component-level repair of the control PCB is not recommended for non-professionals. Replacement of the entire board is the typical remedy.
