Bertazzoni Heritage Dishwasher Code F5: Pressure system failure

What F5 means

On Bertazzoni Heritage, Professional and Master 24-inch dishwashers such as the DW24T3IXV, DW24S3IPV and DW24T2IXB, F5 means the pressure system has failed. The dishwasher can no longer read the water level through its pressure sensing, and the only recommended step is to contact service. The cycle stops and F5 stays on the display until the problem is dealt with. The load stays unwashed until the reading is restored.

Common causes of F5

Pressure switch or sensor not reporting water level
Small air tube to the sensor blocked or loose
Connection between the sensor and the control board interrupted
Control board unable to read the pressure signal

✓ One safe check you can try

1. Press Cancel and let the dishwasher drain. 2. Check that the filter at the bottom of the tub is clean and seated. 3. Close the door firmly and run a short cycle. 4. If F5 appears again, leave the dishwasher off and call us. Please do not open any panels.

! Why to stop there

The pressure system decides how much water goes in, so a wrong reading can cause an overfill or a dry run.
Tracing a sensor problem requires measuring tools and access behind the panel.
Repeated restarts do not clear a sensing failure.
We give you a written price first, and our repair carries a 30-day workmanship 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.

F5F5 questions

What does the pressure system do?

It tells the dishwasher how much water is in the tub so it can fill and drain correctly. F5 means it cannot get that reading, so the control stops the cycle.

Is there anything I can do for F5?

The recommended step is to contact service. A clean filter and a firmly closed door are worth checking first, since they cost nothing, but the sensing part itself needs a technician with a meter.

Does F5 affect the 18-inch models too?

Yes. The 18-inch DW18S2IXV and DW18S2IPV use the same list of codes, so F5 means the same thing there and the same advice applies. Check the filter, then call us if F5 stays on.
