I noticed that my Weil McLean ultra 155 boiler had A control fault error lockout. This is the second Time It has happened this season I wonder what could be causing this error just trying to get ahead of a problem just in case one might be brewing over the years. The spoiler has been very fickle however, this wonderful community has helped me problem solve many of my issues the boiler is working fine at the moment, and once I clear the lock out, there’s no issues hope to hear from somebody to shed some light on this Error code

    What series? They're all control fault lockouts. If Series 3 or 4, it should say the reason for lockout, i.e. , temperature high limit, ignition failure, LWCO fault, etc.

    In the past if I needed a new igniter I would get a ignition error

    05,06,08,09,15,16,17,60,61, all lead to U-Control Module Failure. Are you getting one of these codes?

    When I go into the unit on the errors and I see it’s a control fault error when I click on the only option it gives me is to reset it and when I go into the lockout.  I don’t see anything on why the fault occurred The units working fine right now. Next time I get the  Fault How can I see which error code cause the fault without clearing, or resetting it in the error submenu
