How to fix insufficient flow in my STIEBEL ELTRON Water Heater?
- GGregory TorresAug 9, 2025
If you're experiencing insufficient flow from your STIEBEL ELTRON Water Heater, it could be due to several reasons. First, check if the ECO mode is activated (indicated by the 8 l/min symbol); if so, press the ECO push-button to deactivate it. Also, the shower head or rose might be blocked with limescale, requiring descaling or replacement. Another possible cause is dirt in the system, which would require a service engineer to clean the filter. If the inlet temperature is above 60 °C, a user or qualified installer should limit it to below 60 °C. Finally, the air detection system might be sensing air in the water, causing the heating power to switch off; in this case, the unit should return to normal operation shortly.
