Bertazzoni Heritage Dishwasher Code F6: Heater sensor failure

What F6 means

On current Bertazzoni Heritage, Professional and Master dishwashers such as the DW24T3IXV, DW24S3IPV and DW18S2IPV, F6 means a failure of the heater sensor. The sensor reports the water temperature to the control, and without a reading the dishwasher cannot manage heating safely. The recommended step is to contact service. The wash stops and F6 appears on the display. Dishes may be left cool and unfinished.

Common causes of F6

Heater temperature sensor open or shorted
Loose connector between the sensor and the control
Control board unable to read the sensor signal
Wiring near the heater damaged

✓ One safe check you can try

1. Press Cancel and let the dishwasher drain. 2. Open the door and let the tub cool if the dishes feel hot. 3. Switch the dishwasher off at the breaker for one minute and back on. 4. Try a short cycle. 5. If F6 shows again, stop using the dishwasher and call us.

! Why to stop there

Without a temperature reading the dishwasher cannot heat the water safely.
The sensor sits near the heating element, which carries line voltage.
Swapping parts without testing can cost more than a proper diagnosis.
Your price is given in writing first, and the 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.

F6F6 questions

What is the heater sensor?

It is the temperature sensing part that tells the control how warm the water is. If its reading is missing or out of range, the dishwasher shows F6 and stops.

Is F6 the same as F8?

No. F6 is the heater sensor, while F8 is a heater error. They are close, so a technician will test both the sensor and the element before deciding on a repair.

Will the dishes be clean if I keep running cycles?

Probably not well. Without the right temperature reading the dishwasher will not heat correctly, so the load may come out greasy. Call us instead of repeating the cycle again and again.
