Lochinvar Boiler Repair in Delta
Red Seal–certified Lochinvar boiler repair for Delta homes and buildings. We diagnose three-digit SMART-system fault codes (E117, E125…) on the touchscreen and get your heat and hot water back — same-day available.
Lochinvar boilers — American commercial-grade condensing boilers with the SMART touchscreen control platform — most common in Metro Vancouver commercial buildings, multi-family complexes, and institutional facilities. If yours is showing a fault in Delta, our Red Seal Gas Fitter–certified technicians service Knight XL / Knight WH and commercial Crest Series condensing boilers with the proprietary SMART control system across the Richmond/Delta area.
Delta's farm properties often require dual boilers or larger BTU units for outbuildings. We provide commercial-grade installations for residential acreages.

Common Lochinvar Faults We Repair in Delta
Lochinvar reports problems through three-digit SMART-system fault codes (E117, E125…) on the touchscreen. These are the faults our technicians diagnose most often on Delta service calls:
- SMART System Communication Faults
The SMART touchscreen controller talks to sensors and safety devices over a digital bus. Communication faults can come from wiring corrosion in commercial environments, PCB aging, or ground faults introduced during third-party electrical work — diagnosis needs equipment that reads Lochinvar’s communication protocol.
- E117Ignition Failure
The boiler failed to establish ignition within the permitted trial period — a degraded igniter electrode, gas-valve issues, burner-to-heat-exchanger alignment (more relevant on commercial Crest units), or inadequate combustion air in a tight mechanical room. Investigate promptly: repeated attempts can accumulate unburned gas.
- E125Water-Temperature Sensor Out of Range
The water-temperature sensor reads outside the expected range — a failed sensor, a wiring fault to the SMART board, or a genuine abnormal-temperature condition from flow restriction or modulation issues. We carry Knight-series temperature-sensor replacements.
- Heat-Exchanger Scale Buildup
The Knight series uses a stainless-steel fire-tube heat exchanger. In large commercial systems where water chemistry is not actively monitored, scale and inhibitor depletion reduce thermal transfer and can cause pitting. We recommend water treatment and annual inhibitor testing for commercial installs.
- Combustion-Blower Issues
The induced-draft combustion blower supplies air to the burner. Bearing wear — common in high-run-hour commercial units — causes abnormal noise, incomplete combustion-air delivery, and eventually flue-condition fault codes. Blower-motor replacement on Knight units is a routine repair.
