Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the appliance before removing the control panel.
Step-by-step:
- Dry the panel: If the top panel has been exposed to spills or condensation, wipe it dry. Leave the unit unplugged with the lid open for several hours to allow moisture to evaporate.
- Inspect the keypad: Remove the top cover to access the control panel PCB. Check for signs of corrosion or liquid damage.
- Check cable connections: Reseat the cable between the keypad/display board and the main control board.
- Test buttons: With the unit reassembled and plugged in, press each button individually. If some buttons do not respond or trigger E8, the keypad membrane is likely faulty.
When to call a technician: Persistent E8 usually requires replacement of the control panel assembly or UI PCB.
