Signs You Need Tankless Water Heater Repair Right Now
Tankless units are reliable, but they do develop faults over time. Catching a problem early prevents a small repair from becoming a full replacement. Here are six warning signs to watch for.
Error Codes on the Display
Most tankless units display fault codes when something goes wrong. Navien, Rinnai and Noritz all use specific codes for ignition failure, overheating and flow sensor faults. Our technicians read and resolve every common error code on the same visit.
No Hot Water or Inconsistent Temperature
If your tankless unit fires up but delivers lukewarm water, or cuts out mid-shower, the problem is likely a faulty flow sensor, a scale-blocked heat exchanger or a failing igniter. All three are repairable on the spot.
Ignition or Flame Failure
A unit that clicks but fails to ignite, or lights and then shuts off immediately, usually has a gas supply issue, a faulty igniter or a problem with the flame sensor. Our gas-licensed technicians diagnose and fix these safely.
Water Leaking from the Unit
Any moisture around your tankless unit is a warning sign. Leaks often come from loose fittings, a cracked heat exchanger or a failing pressure relief valve. Left untreated, leaks cause water damage and void manufacturer warranties.
Low Hot Water Pressure
Reduced hot water pressure on a tankless system often means scale buildup inside the heat exchanger or a clogged inlet filter. Annual descaling and filter cleaning restore full flow and prevent damage to internal components.
Unit Has Not Been Serviced in Over a Year
These units require annual maintenance to stay efficient and to keep manufacturer warranties valid. If your unit has not been serviced in the past 12 months, a descale and inspection could prevent a breakdown before it happens.
Common Tankless Water Heater Problems We Fix
Our Red Seal certified technicians have diagnosed and fixed every type of tank and heating fault across the Lower Mainland. Here are the faults we see most often and how we resolve them.
Scale and Mineral Buildup
Hard water in Vancouver deposits calcium and magnesium inside the heat exchanger over time. This reduces efficiency, causes overheating and triggers error codes. We flush and descale the unit to restore performance and prevent long-term damage.
Flow Sensor Failure
The flow sensor tells the unit when water is running and triggers the burner. When it fails, the unit produces no heat or fires inconsistently. We test and replace flow sensors on all Navien, Rinnai, Noritz and Bosch units.
Igniter and Flame Sensor Issues
A worn igniter or dirty flame sensor prevents the burner from lighting or causes it to shut down on safety lockout. We carry replacement igniters and sensors for all major brands and complete most repairs during a single visit.
Control Board Faults
The control board manages every function on a tankless unit. When it develops a fault, the unit may display incorrect error codes, fail to respond to temperature settings or shut down without warning. We test and replace boards on all major models.
Venting and Exhaust Problems
Blocked or improperly installed venting causes carbon monoxide risks and triggers safety shutdowns. Our technicians inspect the full exhaust system, clear obstructions and correct any venting issues to BC Safety Authority standards.
Pressure Relief Valve Issues
The T&P valve protects your unit from excess pressure buildup. A leaking or failing valve needs immediate attention. We inspect and replace pressure relief valves on every tankless service call we attend across Metro Vancouver.
