  If the power lamp isn't on and the water isn't hot, the issue might be due to several reasons. First, check the breaker to ensure the unit is receiving power. Second, inspect the power line connections at the contact points and fix any looseness. Lastly, the thermal cut-out (TCO) might be triggered; in this case, reset the thermal cut-out and check the thermostat.

  If your STIEBEL ELTRON Boiler's main breaker keeps cutting off, it could be due to a few reasons. The main breaker might be overloaded, so try turning off other appliances to reduce the current draw. Alternatively, there might be a wrong connection in the power line, in which case you should replace the main breaker. Also, ensure the power lines L, N, and G are reconnected properly.
