Display shows E10 and the unit shuts down shortly after starting a brew cycle; sometimes accompanied by a faint burning smell.

Safety first: Immediately unplug the coffee maker if you smell burning or see smoke. Do not attempt to operate it again until inspected.

• External inspection: Check the power cord for cuts or burns. If damaged, do not use the unit until the cord is replaced.
• Internal visual check (advanced): With the unit unplugged, remove the base and inspect for burnt components, melted insulation, or blackened areas on the control board or around the heater and pump.
• Isolate the fault: If you are experienced with appliance repair, you can disconnect the heater or pump one at a time and test (with extreme caution) to identify which component is causing the overcurrent. This should only be done with proper tools and knowledge.

Due to the risk of fire and electric shock, persistent E10 or any signs of burning require professional diagnosis and likely replacement of the faulty component and possibly the control board.
