How to Fix / Troubleshooting
Safety: Unplug the appliance before any inspection.
- Power reset: Disconnect from mains for 10–15 minutes, then reconnect and try a simple non-pressure program (e.g., sauté or warm).
- Check control panel: Wipe the touch panel or buttons with a slightly damp cloth, then dry. Ensure no buttons are physically stuck or jammed.
- Remove moisture: If steam has entered the control panel area, leave the cooker unplugged in a dry place for 24 hours to allow moisture to evaporate.
- Test different modes: If only one specific program triggers the error, note it; this can indicate a sensor or relay associated with that mode.
- Service: Persistent 'Err' messages usually require diagnostic testing of sensors and the control PCB. Replacement of the main board or keypad PCB may be necessary.
