Bertazzoni Heritage Dishwasher Code F9: Divisor position error

What F9 means

On current Bertazzoni Heritage, Professional and Master dishwashers such as the DW24T3IPV, DW24T2IXB and DW18S2IPV, F9 means a divisor position error. The divisor is the diverter that steers wash water between spray levels, and the control cannot confirm it is in the right position. The recommended step is to contact service. The cycle stops and F9 appears on the display.

Common causes of F9

Diverter motor not turning to its position
Diverter stuck by debris or a hard object
Position signal wire or connector loose
Control board not reading the position correctly

✓ One safe check you can try

1. Press Cancel and let the dishwasher drain. 2. Remove the lower rack and check that nothing is jammed near the spray arm or its base. 3. Clean the filter at the bottom of the tub. 4. Put everything back and run a short cycle. 5. If F9 returns, switch off and call us.

! Why to stop there

The diverter is under the tub and cannot be reached without taking the dishwasher apart.
A jam and a failed motor produce the same code, so testing is needed.
Cycles that cannot change spray levels leave part of the load unwashed.
We provide a written price first, and our repair has a 30-day warranty.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F9F9 questions

What is a divisor in this dishwasher?

It is the part that directs water to the upper or lower spray arms in turn. F9 means the control does not see it where it should be.

Can a spoon or utensil cause F9?

Small items can fall through the rack and jam the area near the spray arm. Checking and clearing that space is a safe first step before calling.

Is F9 the same on the 18-inch models?

Yes. The 18-inch DW18S2IXV and DW18S2IPV use the same list of codes, so F9 still means a divisor position error and the same safe steps apply before you call.
