If the spanner flashes with fault code E3 on your STIEBEL ELTRON Water Heater, it indicates a short circuit in the outlet sensor. Check the outlet sensor and replace it if necessary.
What does spanner flashes with fault code E2 mean on my STIEBEL ELTRON Water Heater?
If the spanner flashes with fault code E2 on your STIEBEL ELTRON Water Heater, it indicates no DHW and could be due to a faulty PCB (lead break or short circuit in inlet sensor).
What to do if the spanner flashes with fault code E1 on my STIEBEL ELTRON DHE 18/21/24?
If the spanner flashes with fault code E1 on your STIEBEL ELTRON Water Heater, it could be due to several reasons: 1. The safety switch wasn't activated during commissioning. To solve this, firmly press the reset button to activate the safety switch. 2. The safety switch was triggered by a high limit safety cut-out. In this case, check the high limit safety cut-out (plug-in connection, connecting cable) and then activate the safety switch. 3. If the safety switch continues to respond after checking the high limit safety cut-out, the high limit safety cut-out might be faulty. Replace it, then activate the safety switch and draw-off with maximum set value for more than 1 minute. 4. A faulty PCB may also cause this issue. Consider replacing the function module.
What to do if my STIEBEL ELTRON DHE 18/21/24 is green flashing, yellow off, red off?
If your STIEBEL ELTRON Water Heater shows a green flashing light, yellow light off, and red light off, it could be due to: 1. No DHW appliance starting flow rate being reached, possibly due to a scaled-up shower head or aerator. Descale or replace the shower head/aerator. 2. The appliance starting flow rate not being reached because the strainer in the cold water inlet is dirty. Clean the strainer. 3. The flow meter not being plugged in. Check the plug-in connection and correct if necessary. 4. A faulty or dirty flow meter. Replace the flow meter. 5. A faulty PCB. Replace the function module.
Why no LED illuminates on my STIEBEL ELTRON DHE 18/21/24?
If no LED illuminates on your STIEBEL ELTRON Water Heater, it could be due to: * One or more missing power supply phases. Check the fuses in the distribution board. * A faulty PCB. Replace the function module.
What does it mean if my STIEBEL ELTRON Water Heater is green flashing, yellow off, red on?
If your STIEBEL ELTRON Water Heater displays a green flashing light, a yellow light off, and a red light on, it could be due to: * One or more missing power supply phases. Check the fuses in the distribution board. * The air detection system responding. Continue draw-off for more than 1 minute.
