A water heater is a device that provides hot water for various purposes, such as bathing, cooking, cleaning, and heating. However, like any other appliance, a water heater can malfunction due to various reasons, causing inconvenience and frustration for the users. There are several reasons why a tankless water heater might malfunction and require water heater repair in Leander, TX, but these three are typically the main culprits.
Mineral Buildup
Tankless water heaters are susceptible to mineral buildup, especially in areas with hard water. Over time, minerals like calcium and magnesium can accumulate inside the unit, leading to reduced water flow, decreased efficiency, and eventually, complete failure. Regular water heater maintenance, such as flushing the system with vinegar or a descaling solution, can help prevent this issue.
Overheating or Overloading
Tankless water heaters have limits to the amount of hot water they can produce at a given time. If you’re demanding more hot water than the unit can handle, it might overheat and shut down. This can happen if multiple hot water fixtures are running simultaneously, or if the unit is undersized for your household’s hot water needs. As such, proper water heater installation is a must.
Additionally, if there’s a problem with the unit’s temperature sensors or controls, it might incorrectly perceive overheating and shut down as a safety measure. A professional inspection should be done to determine if repairs would suffice or if a complete water heater replacement is needed.
Flame Failure or Ignition Problems
A tankless water heater relies on a burner assembly and a flame sensor to heat the water. If there’s a problem with the gas supply, ignition system, or the flame sensor itself, the unit may not function properly. Gas supply issues could be due to a closed gas valve, insufficient gas pressure, or a malfunctioning gas control valve. Ignition problems could stem from a faulty igniter or thermocouple. If the heater cannot ignite the gas, it won’t be able to heat the water.
If you’re experiencing issues with your tankless water heater, it’s essential to consult the manufacturer’s manual or contact a professional technician for proper diagnosis and repair. Attempting to DIY repairs can lead to further damage or tankless water heater safety hazards.
