How to Fix / Troubleshooting
Safety first: Turn off and unplug the machine. Allow it to cool completely and ensure no steam pressure remains.
- Check wand tightness: Gently try to move the steam wand. Excessive play may indicate loose fittings.
- Clean joint area: Wipe away milk residues and scale around the wand base. Visible cracks or splits indicate the wand must be replaced.
- Descale steam circuit: Run a descaling cycle focusing on the steam function to reduce scale that can damage seals.
- If leak persists: The O-rings or wand assembly must be replaced. This involves opening the machine; contact a technician.
