How to Fix / Troubleshooting
Safety first: Unplug the coffee maker immediately. Do not continue using it until the cause of overheating is addressed.
- Allow to cool: Wait at least 45–60 minutes for internal components to cool down.
- Check water supply: Ensure the water tank is full and correctly seated. Never run the machine with an empty tank.
- Descale thoroughly: Run a complete descaling cycle using a Kenwood-approved descaler. Follow the manual carefully, ensuring both coffee and steam circuits are treated.
- Clean coffee outlet: Remove and clean the coffee spout and any removable outlet parts. Use a brush to clear dried coffee residues that may restrict flow.
- If E10 reappears quickly: The thermostat or thermal cut-out may be faulty or the heater is not regulating correctly. This requires professional diagnosis and replacement of the thermostat or thermoblock.
