How to Fix / Troubleshooting
Safety first: Unplug the multicooker before cleaning the control panel.
- Full power reset: Unplug the cooker for at least 10–15 minutes to allow internal capacitors to discharge. Plug back in and try again.
- Clean control panel: Wipe the touch or button panel with a slightly damp, non-abrasive cloth. Dry thoroughly. Moisture or sticky residue can cause false button presses.
- Check for stuck buttons: Press each button individually to ensure it moves freely and is not jammed.
- Use a stable outlet: Plug the cooker directly into a wall outlet, avoiding extension cords or multi-plugs that may cause voltage drops.
- Firmware issues: If Err appears frequently even after resets and cleaning, the control PCB may need replacement. Contact Brock support for service options.
