Steam wand sputtering weakly or not frothing milk at all? A blocked wand is nearly always dried milk clogging the tiny holes in the tip, and it clears with a simple soak.
Here is why the wand blocks and how to clean it.
This article will teach you:
- Why the wand clogs
- How dried milk builds up
- How to clean the tip
- How to prevent it
Why the Wand Blocks
- Dried milk sealing the tip holes.
- Not purging the wand after steaming.
- Milk drawn back into the wand.
- Scale combined with milk residue.
What You’ll Need
- A pin or wand-cleaning tool
- Warm water and a cloth
- A milk-line cleaner
How to Clear a Blocked Wand
- Soak the tip. Remove the tip if possible and soak it in warm water or cleaner.
- Clear the holes. Use a pin to open each tiny hole in the tip.
- Purge steam. Run steam through the clear wand to blow out residue.
- Wipe after use. Wipe and purge the wand every time you steam milk.
Pro Tip: Purge and wipe the wand right after every steaming, while the milk is still wet. Once milk dries in the tip it hardens fast, and that is what causes most blockages.
When to Look a Little Deeper
Because the wand shares the steam system, it helps to check related parts, and reviewing a steam leak, shots with no crema, or a portafilter leak can reveal related issues.
When to Call a Pro
The wand is fully DIY. If steam pressure is weak even with a clear wand, look at the boiler or pump rather than the tip.
Wrapping Up
A blocked wand is just dried milk. Here’s the recap:
- Soak the tip in warm water.
- Clear each hole with a pin.
- Purge steam through it.
- Wipe and purge after every use.
Clean the tip, and frothing returns. You’ve got this.
