Display shows E7 and the Swan coffee maker shuts down shortly after starting or will not complete a brew cycle.

Safety first: Unplug the coffee maker immediately. Do not repeatedly reset and restart, as this can worsen internal damage.

User checks:

• Inspect power cord and plug: Look for cuts, burns, or loose pins. Do not use the appliance if the cord is damaged.
• Check for burning smell: If you smell burnt plastic or insulation, internal components may be shorted.

Technical inspection (for qualified persons only):

• Remove the base and inspect the heating element, pump, and control PCB for visible damage or burn marks.
• Use a multimeter to check resistance of the heating element; a near-zero reading indicates a short.
• Inspect the mains filter (EMI filter) and surge suppressor (MOV) for cracking or charring.
• Replace any shorted component with the correct Swan-specified part. If the control PCB is visibly damaged, replace the entire board.

Warning: Because this error involves mains power and potential fire risk, most users should contact a professional technician rather than attempting repair themselves.
