I have a steam boiler with a Taco Low water cutoff Model

Customer Question

I have a steam boiler with a Taco Low water cutoff Model LTF1203S-1 that keeps shutting down the burner and over filling the boiler. I have skimmed the boiler several times and drained the boiler several times and added a softener to settle down the bouncing water line, but it keeps flooding the boiler. Any suggestion
JA: How long has this been going on? And how severe is the problem?

JA: Do you plan on doing the work yourself?
Customer: yes
JA: Anything else we should know to help you best?
Customer: I put a new LWC last yr and still same problem

Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.

That model doesn't come up in the Taco data base. Are you sure about the number? is this a probe type LWCO? if so did you pull and clean the probe?
