Common Tankless Water Heater Problems We Repair
No Hot Water or Ignition Failure
If your unit isn't producing any hot water, the problem could be a failed igniter, a blocked venting system, a gas supply issue, or a faulty flow sensor. Our technicians perform a full diagnostic to identify the root cause before we start repairs.
Error Codes & Control Board Issues
Modern tankless units display error codes when something goes wrong. These codes can point to anything from a flame failure to a pressure problem or a faulty temperature sensor. We work with all major brands and models, so we can interpret your unit's error codes and address the underlying issue efficiently.
Inconsistent Water Temperature (Hot & Cold Fluctuations)
If your water swings between hot and cold, or never reaches the temperature you set, the likely culprits include a faulty flow sensor, a scaling buildup on the heat exchanger, a miscalibrated thermistor, or a malfunctioning mixing valve. We'll diagnose and repair the issue, so you get steady, reliable hot water every time.
Mineral Scale & Sediment Buildup
Lloydminster's hard water can cause mineral scale to accumulate inside your tankless unit over time, reducing efficiency and eventually causing overheating or unit shutdowns. We perform professional descaling and system flushes to clear buildup and restore your unit to peak performance.

Leaking Connections or Pressure Relief Valve Issues
Leaks around your unit, its connections, or the pressure relief valve should never be ignored. Water damage escalates quickly, and some leaks point to potentially unsafe pressure conditions. Our technicians can assess the source, stop the leak, and replace any faulty components on the spot.
Venting & Exhaust Problems
Improper or obstructed venting can trigger safety shutdowns and, in gas-fired units, create a dangerous situation. We inspect the full venting and exhaust system as part of every service call and clear any blockages or correct any venting deficiencies we find.
Thermostat & Temperature Sensor Failures
If your unit heats water to the wrong temperature, a faulty thermistor or temperature sensor may be to blame. We test and replace these components to restore accurate, safe temperature control.
