Common Weil-McLain Faults We Repair in Mission
Weil-McLain reports problems through displayed fault codes on Evergreen/ECO; no codes on older cast-iron units. These are the faults our technicians diagnose most often on Mission service calls:
- Pilot / Thermocouple Failure (cast iron)
The classic no-heat on older CGa/EG units — a failed thermocouple or dirty pilot assembly. One of the fastest, cheapest no-heat fixes there is.
- Low-Water Cutoff Trips
LWCO devices on cast-iron systems trip on real low water or on sensor fouling — we determine which before resetting.
- Ignition Lockout (Evergreen)
Electrode wear, gas-supply or valve faults preventing light-off on condensing models.
- Condensate Faults (Evergreen)
Blocked or frozen condensate shutting down condensing operation in cold snaps.
- Circulator & Zone Failures
Seized pumps and stuck zone valves leaving rooms cold while the boiler runs.
