I have a customer w a 7 yr old WM boiler- Hydrolevel 450 lwco and a M/M 101? auto feed. the lwco works when draining the excess water from the boiler. Problem is when I shut the power off to service the burner, the feeder feeds when I turn the power back on, regardless of water level and is overfeeding. I think the LWCO is faulty. Am I wrong?

    Doubt it

    I have not personally had the problem as I hate auto feeders.



    However here is a video of Gerry Gill explaining the issue I beleive you are seeing.
