Possible Causes

Corrupted control firmware, Damaged microcontroller on main PCB, Power supply fault on control board, Loose display/control panel ribbon cable

How to Fix / Troubleshooting

Safety first: Unplug the cooker before opening any covers.

Basic reset:

  • Unplug the unit for at least 10 minutes to allow internal capacitors to discharge, then reconnect and test.
  • Try a different outlet or surge-protected power strip to rule out supply issues.

Internal inspection:

  • Remove the control panel cover to access the main PCB and display board.
  • Check ribbon cables: Reseat the ribbon cable between the keypad/display and the main control board.
  • Visual inspection: Look for burned components, bulging capacitors, or scorch marks on the PCB.

Resolution: If E10 persists and there are signs of board damage, the main control board must be replaced. Firmware reprogramming is typically not user-serviceable on MasterPro multicookers and should be handled by an authorized service center.
