Tankless Water Heater Repair

Tankless water heaters are designed for consistent performance. When issues arise, they often show up as temperature problems, error codes, or interruptions in hot water.

Black Hills provides tankless water heater repair for homeowners across Western Washington. Our approach is straightforward. Find out what’s causing the issue, repair what’s needed, and explain what’s going on so you’re not left guessing.

Some problems happen suddenly. Others develop over time. Either way, we work to get the system back to normal operation.

Signs of Issues

Tankless water heater systems often give clear signals when something isn’t right. Paying attention to these signs can help avoid longer disruptions.

Common signs include:

• No hot water at fixtures
• Water temperature changing during use
• Error codes showing on the unit
• Whistling, clicking, or unfamiliar sounds
• Lower water flow on the hot side
• The system shutting off during operation

If you’re noticing these issues, it’s a good time to have the unit checked.

Common Components That Fail

Tankless water heaters rely on several parts working together. When one part starts to fail, the system can struggle to keep up.

Components often involved in tankless water heater repair include:

• Heating elements or gas burners
• Temperature and flow sensors
• Control boards
• Ignition parts
• Internal valves and filters
• Air intake or venting components

Because tankless systems are more complex than traditional tank heaters, proper diagnosis matters. Fixing the symptom without addressing the cause can lead to repeat issues.

Troubleshooting Before Calling a Plumber

There are a few simple things homeowners can check before scheduling service. These steps won’t repair internal problems, but they can help rule out basic issues.

Before calling for tankless water heater repair, you can:

• Look for error codes on the display
• Confirm the unit has power and the breaker hasn’t tripped
• Make sure gas or electrical service is active
• Check that water valves connected to the unit are open
• Look for visible leaks around the system

If the unit still isn’t working properly after these checks, it’s time to call a professional. Avoid opening the unit or resetting it repeatedly.

When to Repair or Replace

Many tankless water heater issues can be repaired, especially when caught early. In other situations, replacement may be the better long-term option.

Repair is often appropriate when:

• A single component has failed
• The system has been maintained
• Problems started recently
• Error codes point to a specific issue

Replacement may make sense when:

• Multiple components are failing
• Repairs have become frequent
• Performance continues to decline
• The unit is nearing the end of its service life
