- Run a descaling cycle focusing on the steam/hot-water outlet.
- After descaling, run several steam bursts with clean water.
Step 3 – Internal inspection (advanced)
- Unplug and remove the cover.
- Locate the steam thermoblock and its NTC sensor.
- Check wiring and connectors for damage or looseness.
Step 4 – Component testing (for technicians)
