About this service
Tankless Water Heater Repair
Tankless Water Heater Repair is for an installed unit with an error code, ignition problem, temperature fluctuation, flow problem, leak, venting concern, condensate issue or recurring lockout. Error codes and symptoms are diagnostic leads, not complete diagnoses.
Repair-versus-replace decisions depend on the exact fault, heat-exchanger and overall condition, installation defects, parts availability, warranty terms, repair cost and homeowner plans. A fixed age threshold does not decide the outcome.
Failure Families and Diagnostic Clues
Ignition and flame faults. Gas supply, ignition components, flame sensing, appliance controls, venting and installation conditions can all contribute. The manufacturer’s code definition and service procedure govern interpretation.
Flow and temperature faults. Inlet restrictions, sensors, controls, mixing, changing demand, recirculation and undersizing can affect activation or outlet temperature. The symptom does not prove one component has failed.
Water quality and heat-exchanger condition. Scale or other deposits may affect some units, but the water source, treatment, maintenance history, model and observed condition determine whether descaling or another service is appropriate.
Venting, condensate and combustion faults. Intake, exhaust, fan, condensate and combustion-related problems require qualified assessment. The Crazy Plumber is a Technical Safety BC (TSBC) licensed gas contractor, TSBC licence No. LGA0213328.
Electrical, control and sensor faults. Power supply, wiring, control boards, thermistors and other sensors vary by model. Do not open the case or test live components. Use the selected manufacturer’s documentation and qualified diagnosis.
Information That Helps Diagnose the Fault
Before the visit, gather what can be observed safely:
- The brand, model and serial number from the exterior rating plate.
- The exact error code and whether the code repeats or changes.
- Whether the symptom follows high demand, low demand, weather, wind or a particular fixture.
- Whether the unit is gas-fired or electric and whether any gas odour is present.
- The installation age, service history and whether descaling or filter service has been documented.
- Recent renovations, gas-appliance changes, outages, plumbing changes or water-treatment changes.
- Visible leakage, condensate overflow or exterior vent obstruction that can be observed without opening the unit.
These details narrow the investigation without assuming the cause or promising that a particular part will be available.
Tell us the brand, model, error code, symptom pattern, service history and any recent renovation, appliance, power or water-treatment changes. Do not open the unit or remain inside to gather information when gas odour or carbon monoxide is suspected.

Spot the signs
Signs a Tankless Unit Needs Assessment
- An error code appears, clears and returns, or several codes appear over time.
- There is no hot water, intermittent hot water or a recurring lockout.
- Outlet temperature changes while fixture demand remains steady.
- The unit no longer activates at demands that previously worked.
- Hot-water flow or performance declines.
- A new fan, ignition, rattling, kettling or other unusual sound appears.
- Water leaks from the case, piping or condensate system.
- Performance changes after a renovation, gas-appliance change, outage, maintenance visit or water-treatment change.
If you smell gas, leave the building immediately. Do not use switches, phones or ignition sources inside. From a safe location, call FortisBC at 1-800-663-9911 or call 911. Do not return until advised it is safe.
Job steps
What the Service Visit Clarifies
- The code and symptom history. Record the code, when it appears, the demand pattern and any recent changes. A repeating code and changing codes can point to different diagnostic paths.
- The operating fundamentals. Assess water flow, gas supply where applicable, venting, condensate, electrical supply and installation conditions before assigning the fault to a component.
- The manufacturer-specific procedure. Use the exact model’s current manual and service information for code definitions, test steps, resets and replacement parts.
- Maintenance versus repair. Determine whether filters, water quality, descaling, condensate service or another maintenance issue is relevant. Maintenance is not assumed to be the cure for every fault.
- Repair versus replacement. Consider condition, installation defects, heat-exchanger integrity, parts availability, warranty terms, repair cost and homeowner plans.
- The next service relationship. An installation defect or capacity problem may route to Tankless Water Heater Installation. Broader condition planning may route to Water Heater Maintenance or Water Heater Flush Service.
Before you book
Questions homeowners ask
Follow the exact manufacturer’s instructions for the model. Do not use a universal reset rule. Record the code before it clears, and arrange assessment when it returns, when the unit locks out or when the instructions direct you to stop.
No hot water without a code can involve power, controls, flow, gas supply where applicable, sensors, settings or the plumbing system. Use only safe exterior observations and the manufacturer’s homeowner instructions. Do not open the unit or test live or gas components.
The decision depends on the exact fault, heat-exchanger and overall condition, installation defects, parts availability, warranty terms, repair cost and homeowner plans. Neither brand category nor a fixed age threshold decides the result.
Colder incoming water increases the temperature rise required to reach the set outlet temperature. Seasonal symptoms can also involve demand, gas supply, venting, freeze protection, filters, controls or installation conditions. Diagnosis must use the actual property and selected unit rather than assume one cause.
