Bertazzoni Master Dishwasher Code F3: Continuous water input

What F3 means

On current Bertazzoni Heritage, Professional and Master dishwashers such as the DW24T3IPV, DW24T2IXB and DW18S2IPV, F3 means continuous water input. Water keeps entering the dishwasher when it should have stopped. The recommended response is to close the water tap and contact service. The machine halts the cycle, and you may see more water in the tub than normal. Keep the tap off until a technician has checked the inlet valve.

Common causes of F3

Inlet valve that does not close fully
Control not shutting off the fill signal
Level detection not reporting the water height
Constant household pressure keeping a worn valve slightly open

✓ One safe check you can try

1. Close the water tap or shutoff valve to the dishwasher. 2. Switch off the dishwasher at its breaker or unplug it. 3. Look under the sink and on the floor for signs of water. 4. Leave the dishwasher off. 5. Call us and give us the model number.

! Why to stop there

An inlet valve that stays open can fill the tub and then the floor.
The valve and level control are inside the cabinet near wiring.
Turning the tap back on to test it without a repair could flood the kitchen.
We give a written price before work and warrant 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.

F3F3 questions

Why is closing the tap the first step for F3?

Because with F3 water is still coming in. Closing the tap stops the supply at once, so the dishwasher cannot overfill while you wait for a technician.

How is F3 different from F1?

F3 reports water entering continuously, while F1 reports overflow. They are related, since an inlet that never shuts can lead to overflow, but each tells us where to start looking.

Can the dishwasher still be used with F3 showing?

No. Keep the water off and the power off. Running it could keep filling the tub, so wait for a technician to test the inlet.
