How to Fix / Troubleshooting
Safety first: Unplug the machine and allow it to cool completely. Steam circuits can remain pressurized.
Step-by-step:
- 1. Clean nozzle: Remove the steam tip or hot-water nozzle and soak in descaling solution. Use a cleaning needle to clear any blocked holes.
- 2. Descale: Run a full descaling program, ensuring the steam/hot-water steps are completed to flush the steam circuit.
- 3. Test flow: After descaling, run hot water and steam for 20–30 seconds to confirm flow.
- 4. Professional service: If there is still no steam or hot water, the steam valve or heater may be defective and should be replaced by Siemens service.
