Most Common Tankless Water Heater Replacement Parts

Tankless water heaters are sophisticated systems with many components that must work together. Over time, some of these parts may wear out, fail, or become clogged — especially in hard water conditions. Here are the most common tankless water heater parts we replace:

1. Flow Sensor

The flow sensor detects water movement and tells the system when to turn on. If this sensor fails or is obstructed, your water heater won’t ignite properly. Signs of failure:

• Water doesn’t get hot
• Error codes indicating no flow
• System doesn’t turn on when tap is opened

---

2. Heat Exchanger

This is the heart of your tankless unit, responsible for heating the water. Over time, scale buildup can cause reduced efficiency, overheating, or internal cracks. Signs of failure:

• Reduced hot water temperature
• Overheating warnings
• Strange noises (popping or hissing)

---

3. Ignition Pack / Igniter

Tankless systems rely on electronic ignition rather than a standing pilot. If the igniter fails, your burner won’t fire up. Signs of failure:

• Clicking sounds with no ignition
• Cold water only
• Frequent ignition failures

---

4. Control Board (PCB)

The main circuit board manages all operations of the tankless system. Power surges, moisture, or internal faults can cause the board to malfunction. Signs of failure:

• Display not working
• System won’t respond to input
• Erratic or inconsistent heating

---

5. Temperature Sensors / Thermistors

These components monitor water temperature and help regulate burner output. A failing sensor can lead to scalding water or no heat at all. Signs of failure:

• Fluctuating water temperature
• Scalding or freezing water
• Error codes related to temp sensors

---

6. Gas Valve

The gas valve regulates fuel flow to the burner. If it's malfunctioning, it could prevent ignition or create a safety risk. Signs of failure:

• No burner flame
• Smell of gas near the unit
• Error codes related to combustion

---

7. Vent Fan / Blower Motor

These parts are essential for drawing in air and expelling combustion gases. If the fan fails, the system may shut down as a safety precaution. Signs of failure:

• Loud or unusual fan noises
• System shuts off mid-cycle
• Error codes indicating venting issues

---

8. Condensate Drain Components (Condensing Models)

Condensing tankless units produce water vapor that must be safely drained. Blocked or broken traps and lines can cause leaks or system lockouts. Signs of failure:

• Water leaking from unit
• Error code for condensate backup
• Visible drain clog or overflow

---

9. Water Valve Assemblies

These manage the flow of water through the unit. Scale, corrosion, or mechanical damage can cause them to stick or leak. Signs of failure:

• Leaking around connections
• Poor water flow
• Uneven heating

---

10. Inlet and Outlet Filters / Screens

Debris or sediment in the water supply can clog these filters, limiting flow and reducing performance. Signs of failure:

• Reduced water pressure
• Error code for flow restriction
• Overheating due to low flow
