VERIFIED
What is in your oven right now
Open the door and look. A sheet of foil on the bottom to catch drips, a pizza stone that has lived on the lower rack for months, a roasting pan pushed to the back wall. Each of these changes how heat and air move around the cavity and where the sensor sits relative to them.
There is no verified fault named for E17, so the contents of the oven are the first, free thing to examine. That also means the meaning for your model is unconfirmed, so the responsible step is to rule out cavity habits before testing parts.
How accessories interfere
- Foil on the floor can reflect heat to the element and the sensor and distort what the control sees.
- A thick stone slows warm-up and leaves the control chasing a number that rises more slowly than expected.
- Trays pressed against the back wall can block airflow or touch the sensor.
- Racks loaded edge to edge can trap hot spots.
What owners report
Preheat takes much longer than usual, then E17 appears. Or the oven behaves for ordinary bakes and shows the code only when the stone is in place. Foil melts onto the bottom after a spill and looks like a gray puddle.
Take-out test
- Let the oven cool, then remove stones, foil, spare racks and trays.
- Wipe any spilled sugar or cheese from the cavity floor with a damp cloth.
- Run a plain preheat to 350 with nothing inside and see if E17 comes back.
If the empty oven shows no code, the stone or liner was the likely contributor. Keep foil on a rack beneath the dish instead of on the floor.
What if it still appears empty
Then the sensor, element and wiring need examining. A technician checks whether the sensor is intact and in position, whether the element delivers its full output and whether melted foil damaged the heating element or the surface beneath it. The sensor is a probe whose resistance tells the control board the cavity temperature, so a probe sitting out of position can give readings that do not match the real heat.

Tell us what lived in the oven, how the foil was used and what the empty-oven test showed. The visit starts with diagnosis, the estimate is in writing and the work waits for your approval.
Cleaning up after foil
If foil has melted or fused, avoid scraping with metal tools. Once the oven is stone cold, soften residue with a damp cloth and a little time, and report any pitting or exposed metal on the cavity floor, because damaged enamel near the element is worth having examined.
Frequently asked questions
Many manuals warn against it because it can damage the surface and interfere with heat, so check yours.
Not directly, but it slows warm-up, which can stress a control that expects a normal climb.
Leave it until cool; do not pry it, as that can chip the enamel.
It separates cavity habits from true faults, which saves a lot of guessing.
Model compatibility: Bertazzoni reuses codes across series and model years, so E17 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
