Below, we’ll review some typical problems and offer advice to help keep your water heater running smoothly.
Common Tankless Water Heater Problems
When your tankless water heater isn’t working as it should, it can be frustrating. Here are some of the most frequent issues and how to address them.
Lack of Hot Water
One of the most common complaints is when the unit fails to produce hot water. This could stem from various causes, such as a closed water valve, a low gas supply, or even a power outage.
How to fix it:
- Check the water valve and ensure its fully open.
- If you suspect a gas supply issue, verify whether other gas appliances in your home are functioning properly.
- For units requiring electricity, inspect your breaker box to ensure the power isn’t off.
- Water Runs Hot, Then Cold
Some users may encounter a frustrating issue where the water gets warm but turns cold intermittently. This “cold water sandwich” problem can often occur with tankless systems.
What to do:
It might be caused by the unit’s inability to keep up with high water usage or flow rates. If this issue persists, you can read more about possible causes and solutions by visiting why my tankless water heater goes cold. Small adjustments to usage patterns or system settings might resolve the issue.
Mineral Build-Up
Hard water can lead to mineral deposits accumulating inside your unit over time, especially if you haven’t performed regular maintenance. This build-up can restrict water flow and reduce efficiency.
How to fix it:
- Describe your water heater using a manufacturer-approved cleaning solution.
- Installing a water softener can help prevent future mineral issues.
- Error Codes on the Display Panel
Modern tankless water heaters often display error codes to identify specific issues. While these codes can be helpful, they can also feel cryptic without some guidance.
What to do:
- Refer to your water heater’s manual for the meaning of the specific error code.
- If you can’t resolve the issue, you may need professional assistance to identify the exact problem.

- Clean or replace water filters regularly to maintain strong, continuous flow.
- Check the venting system for blockages to prevent overheating or improper combustion.
When to Call a Professional
While troubleshooting can often resolve minor issues, some problems, such as gas leaks or severe internal damage, require expert attention. If your efforts don’t seem to work, it’s always better to seek professional help to avoid further complications that might lead to costly repairs.
By addressing problems early and keeping up with maintenance, you’ll get the most out of your tankless water heater and enjoy hot water whenever you need it.
