Tankless Water Heater Repair for Burnaby homes and buildings
Tankless units report faults as codes, and the code is the starting point, not the diagnosis. A code 11 on a Rinnai tells you the burner did not light; it does not tell you whether the cause is a closed valve, low gas pressure, air in a new line, a fouled flame rod, a failed igniter or a board fault. CANRO's technicians test gas supply pressure, ignition and flame signal, the condensate trap and vent, the inlet filter and flow sensor before replacing parts.
Repeated lockouts and temperature swings are often maintenance issues in disguise: a scaled heat exchanger, a blocked inlet screen or a full condensate trap. Where that is the case, the repair becomes a descaling visit and the manufacturer's service reminder is set so it does not recur.
Gas and plumbing permits. The City of Burnaby requires a Gas Permit to install, modify or upgrade any part of a gas system in single and duplex dwellings, and a plumbing permit for plumbing fixtures, which its fee schedule lists as including a water heater. Permits can be applied for through the City's My Permits Portal. Source
Water hardness. Metro Vancouver's 2024 water quality report gives treated-water hardness of about 22 mg/L as CaCO3 from the Capilano and Seymour sources and about 2.5 mg/L from Coquitlam, which is very soft water. Source
Tankless Water Heater Repair in Burnaby: what to expect
Tankless faults in Burnaby announce themselves as codes, and the code is the start of the diagnosis. This site documents Rinnai SENSEI codes such as 11 (no ignition) and the deeper 60-series flame and sensor faults, and Navien models carry their own documentation; a call with the brand, model and code from the rating plate schedules fastest.
Being CANRO's base city, a Burnaby tankless call is a short drive from 6th Street, which matters for the units stacked into townhouse mechanical rooms and laneway walls where access planning is half the job. The same city soft water that slows scale still lets filters, flow sensors, condensate traps and igniters fail in their own time, and the visit checks all of them.
Repeated lockouts and temperature swings are often maintenance in disguise, and where that is the finding the honest repair is a descaling visit with the service reminder reset rather than a parts invoice. CANRO services the tankless brands it lists, including Rinnai, Navien, Noritz, Bosch and Takagi.

Frequently asked questions
Should I reset the unit when it shows a code?
Check the obvious supply items the manual lists, reset once, and if the code returns stop resetting and call. Repeated resets do not clear the cause.
Do you repair Navien and Noritz as well as Rinnai?
CANRO lists Navien, Rinnai, Noritz, Bosch and Takagi among the tankless brands it services. Codes on this site are documented brand by brand; call with the model number if yours is not listed yet.
