Signs You Need to Repair Your Tankless Water Heater
When a tankless water heater begins to struggle, it rarely fails without warning. Small changes in performance often signal underlying issues that need professional attention. Knowing what to look for can help you take action before your hot water disappears completely.
No Hot Water at All
A total loss of hot water often means your system can’t heat at all. This might be due to an internal malfunction, like a failed ignitor or faulty sensor, and requires prompt service.
Inconsistent Performance Across Appliances
When hot water comes and goes across different appliances, there may be an issue with flow regulation or mineral deposits affecting specific outlets. Don’t wait for it to fail completely.
Electrical or Ignition Failures
Trouble starting your unit or keeping it running? These symptoms often signal ignition failure, control board problems, or voltage issues, especially after storms or power outages.
Rusty Water or Unpleasant Taste
Discolored or foul-smelling hot water may indicate corrosion in the unit or sediment buildup caused by Nashville’s hard water. Left untreated, this can shorten the life of your heater and damage connected appliances.
Banging, Clicking, or Unusual Noises
When your system starts making new or louder noises, it’s often reacting to internal restrictions or mechanical trouble. These sounds usually indicate developing problems that shouldn’t be ignored.
Active Leaks or Water Damage Near the Unit
Any moisture around a tankless unit is cause for concern. Leaks may come from worn connections, internal cracks, or failing valves and can quickly lead to property damage.
Components That Typically Require Repairs
As your system ages, some parts naturally see more stress than others. Nashville’s water conditions and daily demand make these particular components more vulnerable.
Some common repair targets include:
- Heat exchangers: Sediment and minerals can clog internal pathways and lead to rust.
- Flow sensors: Often fail due to debris or scale interfering with proper water measurement.
- Gas ignition and burner system: Sometimes burn out or become less responsive in aging systems or homes with electrical instability.
- Temperature sensors: May give false readings, leading to water that’s too hot or too cold.
- Inlet and outlet valves: May become blocked by mineral deposits or start leaking with age.
- Control boards: Prone to failure from moisture intrusion or power surges during severe weather.
Every repair visit includes licensed techs, reliable diagnostics, and stocked trucks ready to tackle the most common tankless water heater issues in Nashville.
