The burner does not start:
The transformer does not works during pre-washing, and then the burner stops: - Transformer failure
The burner does not start: (pre-heated version)
The burner starts but then stops due to missed ignition:
The burner ignites but then shuts down:
The fuel atomization is bad
The combustion is abnormal (smoking flame, sooting) :
The fuel drips through the nozzle after burner shutdown:
No production of hot sanitary water:
Very little production of hot sanitary water:
