How to Fix / Troubleshooting
Safety first: Unplug the cooker before removing the control panel.
- Drying: If a spill occurred on the control panel, wipe it clean and allow the cooker to dry unplugged for 24 hours.
- Inspect ribbon cable (advanced): Remove the front panel and check that the flat cable from the keypad is fully inserted and locked into the connector on the PCB.
- Check for corrosion: Look for green/white deposits on connectors indicating moisture damage.
When to call a technician: Replacement of the touch panel or control board is often required for persistent E17 and should be done by service personnel.
