How to Fix / Troubleshooting
Safety first: Unplug the coffee maker before any internal inspection.
- Power cycle: Disconnect from mains for 10–15 minutes, then reconnect and test. Temporary glitches can sometimes be cleared this way.
- Avoid moisture: Ensure the machine has not been exposed to excessive steam or water around the control panel. Allow it to dry for 24 hours if moisture is suspected.
- Do not open sealed modules: Internal sensor modules and wiring looms should not be tampered with by untrained users.
- Service required: Persistent E16 indicates an internal communication problem that requires diagnostic tools and should be handled by a Kenwood service center.
