F6 flags a faulty heater sensor. The manual says to contact service.
Model compatibility: Bertazzoni reuses codes across series and model years, so F6 / F06 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F6 reports a faulty heater sensor; the manual says to contact service.
A heater and a temperature sensor work as a pair when a dishwasher warms its water. Bertazzoni’s table gives F6, also printed F06, to a faulty sensor, and the single remedy beside it is to contact service.
Three heating faults, one remedy
F6: faulty heater sensor
F7: overheating
F8: heater error
The same instruction follows each of them. The table makes no finer distinction, so separating a bad sensor from a bad heater falls to a technician testing the machine.
Until service arrives
Stop the running program.
Avoid cycling the machine on and off to retest; the sensor is how it knows when heating should end.
Be careful with dishes if a cycle had already started, since the tub water may be hot.
Sensor versus heater
F6 is the part that reports temperature. The heater has a code of its own, F8, so F6 should not be read as a burnt-out heater.
No cold-rinse option is offered in the manual, so leave the dishwasher unused until it has been seen.
Earlier E-code manuals
Sensor entries also exist in the DW18PR, DW24PR and DW24XV documents, one for a cut and one for a short. Bertazzoni does not claim they are F6 under another number, so they are treated separately.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
