EA — Ionization current outside permissible range during calibration (deviation too great)

What does EA mean?

The burner is in a fault mode because the ionization current during calibration deviates too greatly from its previous level, indicating an inconsistency.

• Flue gas recirculation in the flue system
• Very dusty conditions for combustion air in open flue mode
• Faulty boiler coding card

Click steps to track your progress.

1. 1

   Press the reset button 'R' on the boiler.

2. 2

   If in open flue mode, ensure the combustion air intake area is clean and free of excessive dust.

3. 3

   Contact a qualified heating technician to check the flue system for recirculation or, if several reset attempts fail, to replace the boiler coding card.
