The Low Water Cutoff on Your Raypak 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 Raypak systems — including models such as XTherm, XVers, MVB — a failing low water cutoff often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Raypak part.
