If you own a tankless water heater from brands like Rinnai, Noritz, NTI, Bosch, or Rheem, this troubleshooting guide is designed for you. We'll explore the most common issues you might encounter and provide tips on how to address them.
Tankless water heaters are known for their durability and longevity, requiring minimal maintenance. However, despite their efficiency and eco-friendly technology, they can occasionally display error codes or fail, which can lead to costly repairs. Here are four common problems and solutions:
1. “No Hot Water from Tankless Water Heater”
Symptoms: You're not getting hot water, or it takes too long to arrive at the fixture.
Causes:
Overload: If you're using multiple hot water appliances simultaneously, you might be exceeding the capacity of your heater.
Gas Supply: For gas units, ensure the gas valve is open.
Maintenance: Lack of regular maintenance could lead to issues. Consider scheduling periodic checks and possibly investing in a water softener if you have hard water.
Solution: If these steps don't resolve the issue, call a professional from Scenic Air Solutions for a thorough diagnosis.
2. “My Tankless Water Heater Shuts Off During Showers.”
Symptoms: The water heater turns off unexpectedly, especially during showers.
Causes:
Flow Rate: Older units might have a higher minimum flow rate, causing the heater to shut down when the flow is too low to prevent overheating.
Solution:
Check Flow Rate: If you frequently encounter this issue, consider consulting with our technicians about upgrading to a newer model with a lower minimum flow rate, which can handle smaller demands for hot water more effectively.
3. “The Water Heater Reports That the Exhaust Pipe is Blocked”
Symptoms: An error message indicating a blocked exhaust.
Causes:
Ventilation Issues: Tankless heaters require fresh air intake and must expel exhaust. Blockages can occur from dust, debris, or obstructions near the ventilation.
Solution:
Immediate Check: Inspect around the unit for any blockages or debris. Clear any obstructions. If the problem persists, contact Scenic Air Solutions for a professional inspection to ensure all pathways are clear.
4. “My Water Looks or Smells Differently”
Symptoms: Water from your taps might be discolored or have an odd smell.
Causes:
Mineral Buildup: Over time, minerals in the water can accumulate, leading to cloudy or discolored water. Rust can signify internal rust or damaged pipes.
Solution:
Regular Flushing: Use a descaling solution or distilled vinegar to flush the system. Aim to clean your tankless water heater at least biannually to prevent such issues.
