Hello,

Does anyone know what LWCO code ERR 3-1 represents for a Burnham ES2-4 boiler?  The boiler is full of water and it operates fine if I disconnect the LWCO card from the boiler.  Thanks I'm advance.

    Okay so I have been playing around with it and now I am getting ERR 2-2.  Any idea what that code represents? Thanks again.

    Now I'm getting ERR 2-3 without even a card plugged into the panel.  I feel like something is up with the panel internally.

    I figured it out.  I jumped out the IQ Panel and now the boiler fires up.  I'll have to replace the IQ panel.

    Replaced the IQ Panel the other day. The boiler is working fine now. Time to get the two radiant zones going now!

    Hi! I'm having the same Err 3-1 from the LWCO display. I'm trying to figure out if it's the LWCO's issue or the IQ Panel's issue. Any thoughts?
