    Was the water level dropping as a result of the blockage? Was it dropping below the LWCO and the LWCO wasn't triggering?

    I think you'd be surprised how little condensation is flowing in a small boiler so it's possible it wasn't affected at all.

    Well think about it. A boiler with no or low water will fail. Steam goes out no or little water comes back.

    Low water cutoffs are not 100% dependable. No control is.

    If they didn't maintain the boiler water, there's a good chance the low water cut off is mucked up as well.
