I could use some help IDing a sensor 5428 003
The boiler cut on me the other day and the message on the water level master controller showed sensor 5428 003. I have looked through our books and on line I cant find anything on the sensor?
This set up uses a c/b hawk ics controller to control 3 250 hp c/b steam boilers. I am starting to think the issue might be in the hawk controller?
I did get the boiler to reset so it isn't a urgent issue

    @Lewes we have worked on many CB boilers over the years, but I suspect you will have to reach out the manufacturer due to the proprietary Hawk control. There is a reason they use proprietary controls, I'm guessing it's so you have to have them do service.

    It's probably a probe type water level sensor. I would call your local C/B Rep.

    You can try removing and cleaning the probe and check the wiring to the probe. It probably uses a ground return. With 3 boilers you need some spare sensors and other parts on hand

    Contacting Tech. support at Cleaver Brooks is your best bet. Try cleaning the probe(s) as @EBEBRATT-Ed mentioned too. Be sure to let Cleaver Brooks know what's going on before things get worse.
