The table’s wording
For F9 (F09 on some lists) Bertazzoni writes “Divisor position error”. The usual term is diverter: a valve or flap that directs circulating water to one spray level or another, which is why its position matters to the machine.
Only a fault and an action are printed, the action being contact service. A stuck diverter, a motor problem or a failed position sensor are all unmentioned.
Questions
Are the spray arms damaged? Spray arms do not appear in the table, only the diverter position.
