Display shows “E5” and the unit shuts off or resets during brewing.

Safety first: Unplug the coffee maker before opening the base or back panel.

• 1. Try a different outlet: Plug the coffee maker into a dedicated 120V outlet, avoiding shared circuits with high-draw appliances like microwaves.
• 2. Inspect power cord and strain relief: Check where the cord enters the unit for damage or looseness. Tighten the strain relief if needed.
• 3. Check internal connections: Remove the base and verify that the line and neutral wires are firmly attached to the control board and not discolored or burnt.
• 4. Observe for overheating: Look for components on the control board that appear overheated. If present, the board should be replaced.
• 5. Replace control board if necessary: Persistent E5 errors with good external power usually indicate a failing internal power supply on the control board.
