E10 appears and the cooker will not start; often after a power surge or lightning event.
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
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.
