The Wiring Harness on Your Weil-McLain Boiler

The wiring harness ties together the control board, sensors, igniter, valves and pump. Heat-damaged, chafed, or corroded harness connectors cause intermittent faults that are notoriously hard to chase down without proper diagnosis.

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