# Bertazzoni dishwasher error code F9

### What F9 means on a dishwasher

Divisor position error — the valve that sends water to one spray arm or the other is not where the machine expects it. That comes out of the dishwashers manual this maker publishes for the machine, and it is one of only three documents in the whole current catalog that carries a code table at all.

### What to do

- Check nothing is jamming the lower spray arm or sitting under the bottom rack.
- If it returns, it is the divisor mechanism or its position sensor and that is a service call.

### What the repair is

Conditions like this one end at [Dishwasher drain & filter repair](https://bertazzonimiami.support/services/dishwasher-drain-and-filter-repair/) more often than anywhere else. The figure on that page is a starting point; the exact cost is confirmed after an on-site diagnostic and agreed in writing before anything is opened.
