    Why is my STIEBEL ELTRON Water Heater clicking but not heating?
    • A
      Allison BrowningAug 7, 2025
      If your STIEBEL ELTRON Water Heater isn't providing hot water, but you hear a clicking sound, the problem could be a tripped circuit breaker. Try turning the circuit breaker on. Alternatively, the safety thermal cut-out may have tripped; in this case, reset the thermal cut-out.

      If the water from your STIEBEL ELTRON Water Heater isn't warm enough, it could be due to a high water flow. Try reducing the water flow and closing the flow adjustment screw. It could also be that the voltage is too low, so ensure the unit is receiving the correct voltage.

    What to do if my STIEBEL ELTRON DHC 6-2 has no hot water and no audible click?

      Charles ReedAug 27, 2025
      If your STIEBEL ELTRON Water Heater isn't producing hot water and you don't hear a click, the issue might be due to low water flow preventing the flow switch from activating. Try cleaning the faucet aerator. Also, ensure the shut-off valve is completely open. You may also need to open the flow adjustment screw or clean the filter screen at the DHC unit.
