How to Fix / Troubleshooting

Safety first: Immediately switch off and unplug the machine. Do not continue to use it until the source is identified.

Inspection:

  • Check for visible damage: After cooling, open the housing and look for burnt wiring, discolored connectors, or melted plastic.
  • Descale: If no obvious damage is found and the smell is slight, perform a descaling cycle to reduce heater stress.
  • Check pump operation: Ensure the pump is not running without water (always keep the tank filled).

Important: Any sign of burnt components or persistent burning smell requires professional inspection and likely replacement of affected parts.
