The function of the Igniter

The main function of the igniter is to light up the gas. That’s why it’s called an igniter because it’s supposed to ignite the device. When you turn the switch on, you should be able to see a small spark that lights up the pilot.

Why Is My Hot Water Heater Not Igniting?

In most cases, when there is water heater igniter no spark, there is likely something wrong with the spark electrode. Some issues may happen with it:

  • The pilot line may be clogged. Check whether there is debris or dirt that obstructs the line. If there is any, clean it up. You can also consider replacing it.
  • Loose wire connections. When there is one loose wire connection, it may affect the function of the device. Make sure that tightened properly.
  • The piezo igniter may be faulty. If the entire igniter is faulty, then it’s logical if there is no spark.
  • Broken electrode. The electrode is the one responsible for releasing the spark. So, when it’s broken, no spark won’t be generated. It means that you will have to replace the electrode completely.
  • Grime or carbon deposit on the pilot light. When there is a smudge on the pilot light, it may be difficult to spark. You may want to clean the electrode’s tip using sandpaper or dry cloth. It will remove rust, dirt, or debris.
