Heatline Compact boiler fault code F28


I own a Heatline compact boiler, which is approximately three years old. The boiler is displaying a F28 fault code. I have restarted the boiler in order to fix this issue but no success. Has someone faced this problem if yes, then please help me

Thank You


Hi Nick, a fault code F28 on your Heatline compact boiler means “ignition fault”. You have to check the following things for fixing the issue

  • Check ignition wire along with electrode. You have to replace them if needed
  • Carefully, check the different electrode connections. If needed fix them
  • Afterward check the spark gas and position and fix them if required
  • You have to check & fix the different connections, which are positioned at printed circuit board & ignition generator.
