Hi There, i have a Weil Mclain boiler EGH-125 and i have 2 lwco installed on it. i went to try to put it on today and after checking to make sure water lever was good and all, i turned the boiler switch on, the red light on the LWCO s started to blink as usual and as soon as it went off both LWCO started to make clicking noises and the green button started to flash and the burner didnt fire up... could it be the probes need to be cleaned?? any ideas before i start taking things apart?  Thanks

    Phantom water level

    Sometimes the sight-glass can be misleading, if the connections are plugged up, the waterline will show in the glass, but there is not enough water in the boiler to fire.

    Otherwise, the probes may be dirty enough not to register the waterline.

    You should be able to download the manual for the lwco's and then clean the probes.--NBC
