What Error EA01 Means on Your Bosch Boiler
Error EA01 on Bosch boiler systems indicates the ionization current was lost during burner operation. This diagnostic code is generated by the system's control board when sensor readings or operating conditions fall outside the expected range. Bosch equipment uses sophisticated diagnostics to help technicians pinpoint problems accurately. The error code is stored in the control board's memory and can be retrieved even after the system has been reset.
