Bertazzoni Heritage Dishwasher Code F1: Overflow

What F1 means

On current Bertazzoni Heritage, Professional and Master dishwashers such as the DW24T3IXV, DW24S3IPV and the 18-inch DW18S2IPV, F1 means Overflow. The recommended response is to unplug the machine, close the water tap and contact service. The dishwasher stops because water has risen higher than it should inside, and you will see F1 on the display, often with water at the bottom of the tub or base.

Common causes of F1

Water inlet not shutting off and overfilling the tub
Leak from a hose, door seal or fitting into the base
Drain not carrying water away properly
Level detection not reading correctly

✓ One safe check you can try

1. Unplug the dishwasher or switch off its breaker. 2. Close the water tap or shutoff valve to the dishwasher. 3. Mop up water on the floor and inside the tub. 4. Check under the sink for a wet hose connection. 5. Do not restart. Call us and tell us the model.

! Why to stop there

An overflow can damage cabinets and flooring quickly.
Finding where the extra water came from needs a check of the inlet valve, the seals and the drain together.
The inside of the base is close to wiring, so it must not be explored with power on.
We quote in writing first and stand behind the repair for 30 days.

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.

F1F1 questions

What should I do first when F1 appears?

Unplug the dishwasher, close the water tap and contact service. Doing that stops more water entering while the cause is found, and it protects the floor and cabinets.

Is F1 on the Heritage the same as E4 on older models?

They carry the same idea. The older DW24XV, DW24XT, DW24PR and DW18PR use E4 for overflow, while the current Heritage, Professional and Master machines use F1.

Can I run the drain cycle to clear F1?

The tap and power should be off first. Once the cause is removed, a technician can test the drain safely. Running the machine with a leak risks more water on your floor.
