Machine turns off by itself during brewing or shortly after starting.

Safety first: Unplug the machine and allow it to cool before inspection.

Inspection:

• Check ventilation: Ensure the machine has adequate space around it and vents are not blocked.
• Inspect internal connections: Remove the housing and check all mains connectors for looseness or discoloration. Tighten or replace as needed.
• Look for heat damage: Examine the power supply section of the PCB for darkened areas or bulging capacitors. These indicate overheating and require board repair or replacement.
• Test with no load: Run the machine without brewing (idle) to see if it still shuts off. If it only trips under load, a heater or pump may be drawing too much current and should be tested by a technician.
