Generally, this happens for two reasons: poor quality water inlet or, more commonly, external contamination of the boiler due to incomplete maintenance. The steam handle pushes out all steam from the boiler through a direct connection. When the steam tap is not properly maintained, milk can enter the boiler and contaminate it. The only way to resolve this issue is to perform a deep cleaning purge, remove the boiler, immerse it in acids, and reinstall it.
Maintaining the steam tap of your espresso machine is crucial for ensuring optimal performance and longevity. Here’s a step-by-step guide to help you:
Daily Maintenance
- Clean the Steam Wand: After each use, wipe the steam wand with a damp cloth to remove any milk residue. Purge the wand by turning on the steam for a few seconds.
- Check for Blockages: Use a pin or a small brush to clean the steam wand tip to prevent blockages.
Weekly Maintenance
- Deep Clean the Steam Wand: Remove the steam wand tip and soak it in a solution of warm water and a mild detergent for about 20 minutes. Rinse thoroughly before reattaching.
- Inspect the Steam Tap: Check the steam tap for any signs of wear or leaks. Tighten any loose connections.
Monthly Maintenance
-
Lubricate the Ball Joint (if apply): Apply food-grade grease to the ball joint of the steam tap to ensure smooth operation.
General Tips
- Regular Purging: Always purge the steam wand before and after each use to maintain steam pressure and prevent milk from entering the boiler.
- Proper Storage: Ensure the steam tap is closed properly when not in use to avoid contamination.
By following these maintenance steps, you can keep your espresso machine’s steam tap in excellent condition and ensure a consistent quality of steam for frothing milk.
