What to do if ELRO KT200TS heating boiler won't turn on but the wheel is spinning?
- BbryanreeseAug 11, 2025
If your ELRO Thermostat's heating boiler isn't turning on but the wheel is spinning, there are several potential causes. First, ensure you are using only ALKALI batteries, as incorrect batteries can cause this issue. You should also replace the batteries, as nearly depleted batteries can prevent the boiler from activating. Check and secure the cable connection, as a loose connection at the Coronet-Anschluss could be the problem. Finally, make sure the heating boiler is properly connected.
