Display shows E13 and the machine shuts down shortly after starting, sometimes with a burning smell.

Safety first: Immediately unplug the coffee maker. Do not continue using it if you smell burning; risk of fire or further damage.

Steps:

• Allow full cooling: Let the machine cool for at least 45–60 minutes before touching internal components.
• Check for visible damage: Remove covers and inspect the boiler/thermoblock area for burnt insulation, melted plastic, or darkened metal.
• Descale thoroughly: If no severe damage is visible, descale the machine to restore proper heat transfer and water flow.
• Inspect thermostats and thermal fuses: Locate the thermostats and thermal fuses on the boiler. A blown fuse indicates serious overheating and must be replaced with the exact rated part.
• Do not bypass safety devices: Never short-circuit a thermal fuse or thermostat to "test" the machine. This is dangerous.
• Service recommendation: Because E13 indicates overheating, have the unit inspected by a qualified technician to ensure safe operation before further use.
