Fire Hazards:

• Overheating: Blockages in the water reservoir or brew basket can cause the heating element to overheat, potentially igniting nearby materials. Listen for unusual sounds and check for steam escaping from unintended areas.
• Proximity to Flammables: Placing the coffee maker too close to curtains, paper towels, or other combustible items can lead to ignition if the machine becomes hot. Visually assess the surrounding area for any potential fire risks.
• Malfunctioning Thermostat/Safety Shut-off: If the machine doesn’t shut off automatically when the brew cycle is complete or if it overheats, it poses a fire risk. Observe if the machine continues to heat excessively after brewing.
• Clogged Drip Tray/Carafe Area: Coffee residue buildup can become a fire hazard if it overheats. Check the drip tray and carafe holder for accumulated grounds and oils.

Fire hazards can arise from overheating, especially if your electric coffee maker has a blockage. Regular cleaning is key, but if you’re looking for added peace of mind, a newer model with advanced safety features might be a good investment.
