If your steam wand is not producing adequate steam or not reaching the correct temperature, consider the following:
- Water Level: Ensure the water tank has sufficient water.
- Red Dust Plug: Verify that the red dust plug at the bottom of the water tank has been removed. This is crucial for proper water flow.

- Temperature Gauge: Confirm the temperature gauge needle is in the red zone for optimal steam temperature.
