Before you book,
in this order.

Each step comes from Bertazzoni's own guidance for rES on its ovens. Follow it to the end: the last card says whether this is a visit.

01

Slide the water tank fully into its slot above the cavity.

02

Check the message clears once the tank is seated.

03

If rES stays with the tank in place, book a visit.

Still there?

It usually turns into steam system repair. Book with the code and the model number.

What not to do

rES does not mean the tank is empty; that is -L0-.

In Bertazzoni's own words

If the indication “rES” appears, it means that the water tank was not properly inserted.

Questions
about rES.

Can I clear rES myself?
Slide the water tank fully into its slot above the cavity. If it comes back, it needs a visit.
My Bertazzoni steam oven shows rES right after I filled it. Why?
The tank is probably not pushed all the way in. Seat it firmly in its slot and the message should clear.
Can I cook on my Bertazzoni steam oven while rES is showing?
Bertazzoni says every function needs the water tank. Put it back properly first.

Still showing rES?
