Probe

Make sure 1st 2 threads on probe do not have dope or teflon tape on them.Might be a bad LWCO?

Guage glass ....

If this is the same as the Dunkirk Plymouth, the guage glass is very long on the electronic cut off units and low water is about half way up the glass. Check the actual probe level... it is very high.

Also check

that the pipes between the boiler and the gauge glass are clear. If they are not, you can get a false reading which confuses the situation.
