Low Water Cut Off

*Is a Cycleguard supposed to shut the Boiler down when water gets too low or is it another box that does that?
Cause when water gets low nothing is shutting Boiler down.
*When water gets low the Cycleguards two little lights go on and asks for water..which automatically goes on..but I have the water feed off cause i am worried Cycleguard will not stop feeding water(as it once did in the past) So I go check water level every few days.
The other day I went down and water was very very low the two lights asking for water on Cycleguard were on, so I turned on feed and added more water to boiler..water went up to level ..but lights did not turn off on Cycleguard.
Boiler would not turn on for some time..but eventually went back on..Is this Cycleguard unit sounding faulty?
Thanks

That said I would get some sandpaper, turn the power off and check and sand contacts. See if any seem sticky.
If that doesn't work you might need to replace it.

1. Turn off the boiler by its switch, and turn off the water valve in front of the auto feed.
2. Set up the thermostat high, so it will fire when turned back on.
3. Drain out the boiler water to the bottom of the gauge glass.
4. Turn on the switch-the boiler should not fire.
5. Turn on the auto feed, and wait for it to fill the boiler. When the correct level has been obtained, the boiler should fire.
6. Set the thermostat back down.
7. If the LWCO fails on #4, and 5, call a technician who is familiar with hydronic systems, as not every plumber is.
8. I suggest going with the model of LWCO which does not cut off the burner every few minutes, (ie. Safguard, by the same company). It should have a water meter on it.—NBC
