Reasons why the condensate- or boiler-feed pump is

The second switch, set to operate at a lower boiler water level, usually serves as a low-water cutoff switch, although you can also use it as an alarm switch. If the pump controller isn't level, the switches may trip too soon or too late, causing the boiler-feed pump to operate erratically. The wrong pump controller is on the boiler.

The needed repairs can range from retubing to total destruction of the unit if the drums overheat. In the event of low water, the low-water trips will trip the burner (or fuel flow for solid fuel boilers) and shut down the forced draft fan. This shuts down the heat input. The trips should be installed at a water level that will prevent damage.
