Milk residue has hardened inside the steam wand tip, blocking the holes.
First, wipe the wand with a damp cloth after each use. Then, with the steam wand tip over the drip tray, briefly turn the STEAM/HOT WATER dial to the STEAM position to clear remaining milk.
If holes are still blocked:
- Set the STEAM/HOT WATER dial to STANDBY.
- Press POWER to switch off and let the machine cool.
- Use the pin on the end of the provided cleaning tool to unblock each hole.
IF THAT DIDN'T WORK: For a severe blockage, remove the steam wand tip using the integrated spanner in the cleaning tool. Soak the tip in hot water. Use the pin tool to unblock the holes before re-attaching.
HEADS UP: Always purge the steam wand after texturing milk to prevent this. Direct the steam over the drip tray, not your hand or cup.
