No power?

Hey y'all. I've got a weil-Mclain VHE6 boiler and our of the blue it completely stopped cycling on. The internet says there's a reset button, but I'm not finding one, and the LED is not lit. I somehow got it to kick on once for about half an hour by flipping the breaker and the switch, but that has not worked today. Am I completely missing something ?

    What LED are you looking for? I think the only LED there would be on the ignition control and I think that would only be lit on a call for heat.

    Usually there's an LED on the Honeywell box that's there, but it's not on. The thermostat currently reads at 50 and is set for 70 and nothing is kicking on. I've flipped the breakers and the cut off switch and the on off knob there on the wall. I am wondering if it may be my thermostat?

    Noona, there is just too many things that can cause that problem. You need a professional hydronics guy come in and find the problem.

    If your boiler is plugged into a wall outlet, unplug the boiler and plug a lamp into it and see if it lights up. If the lamp lights up you have power to the boiler and something else other than loss of power is the problem. You can use a hair dryer.

    If the lamp doesn't lit up, have someone check the breaker. Breakers do go bad.

    I thought as much but I was hoping that might not be the case. This is my first place with a boiler system like this. I'm much better with forced air furnaces. Thank you, anyway!

    Breakers do go bad — but I would ay that that's the least likely problem.

    All boilers will have an emergency power switch somewhere nearby. I should be labelled, but… maybe not. Is it turned on? Did someonw mistake it for a light switch? It's happened… are there more than one? Perhaps one near the boiler and one near the entrance to the basement?

    After tha… there are a number of safeties on a gas boiler, any one of which can shut it off, and several of which need to be reset manually — after you find out why they tripped. This may be something for a decent tach. to play with; if they are any good they should be able to identify the problem, if not the root cause, very easily.

    Does anything click when you turn the power on? Is the inducer fan warm or humming or running? Is there a damper on the flue and does it open when you power on the boiler? Is the thermostat electronic or mechanical?

    A pic from further back may help. It could have a low water safety switch that is causing a no power condition.
