What you will notice
You boil water on the front left, start a sauté on the rear left, and the code appears within a minute or two. Switch either one off and things settle. Some owners notice the effect on a bridged or flexible zone, others on a pair at the same side of the glass. Noting which two zones trigger it, and in what order you switched them on, is the heart of the report. Induction zones heat the pan through a coil under the glass, so a power stage shared by two coils can be stressed by both at once even though each zone works alone.
Checks you can do yourself
- Try different pairs, such as front left with rear right, to map which combinations trigger E13.
- Note the order in which the zones were switched on and the heat levels chosen.
- Check that no pan overhangs a neighboring zone, which can confuse sensing near the edge. A warped or off-center pan can also affect pan detection, so use the same flat pan for each pairing.
Where the work starts inside the cooktop
When two particular zones cause trouble, the first look goes to what they share: the power stage that serves that pair, its heat sink and airflow, and the wiring between that stage and the zones. The panel and the other zones are examined only afterward.
What the code does and does not tell us
We do not treat E13 as having one fixed meaning on every Bertazzoni cooktop, since generations differ. The behavior of paired zones is more informative than the characters: it hints at something the two zones share, such as a power stage or a section of cooling, though only a measurement on the exact model confirms that. A pair that triggers the code in one order but not the other suggests timing or load rather than a failed zone.
Cooktops installed in an island, with deep drawers below, tend to run warmer in the shared stage area. Mention the layout if you have this arrangement.
The order of use can matter as much as the pair. If E13 only appears when the second zone is started while the first is on boost, say so, because that suggests a peak-demand moment rather than a steady overload. A short note listing the heat levels is worth far more than a general description.
When to book a visit
Pair-dependent faults are repeatable, which makes the technician’s job efficient. The cooktop is run with the same pairing while supply, temperature and zone output are read, an activity that involves live parts and so is not suited to home testing. Your pair map is the best preparation.
Frequently asked questions
Zones that share a power stage or cooling area add their loads together. Other pairs may sit on separate stages and cope fine.
As a short-term workaround, yes. It does not remove the cause, so book the visit.
Then something common to all zones is more likely, and the supply or main board becomes the first suspect.
Model compatibility: Bertazzoni reuses codes across series and model years, so E13 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
