If the boiler is not working because of lack of power, it may be because the breaker is tripped or the fuse that controls the boiler is blown. To repair those issues, reset the tripped circuit breaker or replace the fuse.

If a boiler isn't working because the water is too low, maintain the boiler's water level at half full. The boiler should have a filling system that uses a pressure release valve in order to maintain water levels. If the boiler does not have such a valve, open the water feed valve and manually feed the unit until it reaches 12 pounds per square inch.
