What to do if the Boiler Low Water lamp is illuminated and Audible alarm sounds in my FULTON Boiler?
- RrpattonAug 3, 2025
If the FULTON Boiler's low water lamp is illuminated and the audible alarm sounds, it could be due to several reasons. First, ensure that the feedwater supply line valves are open and that the ball valve in the tank is operating correctly by removing the inspection cover on the tank. There might be an obstruction in the feedwater line to the pump, so verify that the shut-off valve below the tank is open, remove and clean the filter in the strainer, and check the non-return valve. Another possible cause is an air lock in the pump, which can be resolved by bleeding the pump at the point provided. Also, check the connections to the water level probes and ensure that each relay is pressed firmly home on its base.
