Possible Causes
Failed microcontroller on main PCB, Corrupted firmware, Power surge damage to control board, Loose display/control panel ribbon cable
How to Fix / Troubleshooting
Safety first: Unplug the cooker before any disassembly.
- Power cycle: Disconnect from mains for at least 10 minutes to allow internal capacitors to discharge, then reconnect and test. Sometimes transient faults clear after a full reset.
- Check supply voltage: Ensure the cooker is connected to a stable 220–240 V outlet (or as specified for your region). Avoid using undersized extension cords.
- Inspect control connections: Remove the top or front panel (depending on model) to access the control PCB. Verify that the ribbon cable between the keypad/display and main PCB is fully seated and not damaged.
- Look for burn marks: Examine the PCB for burnt components, bulging capacitors, or cracked solder joints. Any visible damage usually requires board replacement.
- Replace PCB: If E7 persists and no external cause is found, replace the main control PCB with a Binatone‑compatible board. Firmware programming may be required and is best done by an authorized service center.
