What to do if my Kärcher SC 4 has no steam?
- Eevelyn01Jul 28, 2025
If there's no steam coming from your Kärcher Steam Cleaner, several things could be happening. First, the water reservoir might be empty; fill it to the MAX marking. Second, the steam boiler might be empty, triggering the pump's overheating protection; in this case, turn the appliance off, fill the water reservoir, and then turn the appliance back on. Finally, the water reservoir might not be inserted correctly or could be calcified; remove it, rinse it, and then re-insert it, pressing down until it's secure.
