    Hard lockout weil mclain ultra 230 plus
    Have a weil mclain ultra 230 plus boiler. Display went blank, unit won't start. When I press reset the blower works for a second. The circulating pump does run. Is there a another reset I can do or is it the control module

    That seems to be a fairly common problem based on previous post with your model. You might want to contact WM directly as they may have an easy fix or at least give you some help.

    Without further facts or knowing your own proficiency, contacting the manufacturer, or the installer, would be the way to go before you do your own checks or fixes. You should have a contact number with your service warranty.
