The Low Water Cutoff on Your Weil-McLain Boiler

The low water cutoff (LWCO) is a safety control that shuts the burner off if the boiler loses water, preventing dangerous dry-firing. It is required on many systems and must never be bypassed.

On Weil-McLain systems — including models such as ECO, ECO Tec, Ultra — a failing low water cutoff often shows up as low water cutoff trip or related symptoms. We diagnose it precisely and install the correct genuine Weil-McLain part.
