- Check the water inlet and outlet for blockages or scale deposits. Use a soft brush if needed.

Step 4: Descale and Use Cleaning Tablets
If you suspect mineral buildup, descale the machine using a descaling solution or Breville-approved cleaning tablets. Follow the manufacturer’s instructions carefully to avoid damage.
