Temporary microcontroller glitch, Loose internal connector (sensor, heater, or keypad), Faulty touch panel or keypad matrix
How to Fix / Troubleshooting
Safety first: Disconnect from mains before opening the housing.
- Soft reset: Unplug the cooker for 10–15 minutes. Press and hold the Start/Stop or Keep Warm button (if possible) while plugging back in to force a reset on some models.
- Check connectors: Remove the top or front panel to access the control board. Reseat all ribbon cables and connectors (keypad, display, sensors, heater).
- Inspect keypad: If some buttons do not respond or are stuck, clean around the touch panel. For membrane keypads, check for cracks or moisture under the overlay.
- Test operation: Reassemble and test a basic program. If 'Err' reappears, the control board or keypad assembly may need replacement.
