Bertazzoni PE244INDXV Cooktop Code E4: IGBT Sensor Short Circuit

What E4 means

On Bertazzoni professional induction cooktops such as the PE244INDXV, PE304INDXV and PE365INDXV, E4 is an error message from the IGBT sensor, showing a short circuit. The IGBT is the power switching part that drives the induction coil. The official remedy is to replace the mainboard. The cooktop will not heat while E4 shows. The cooktop will not heat until the board is dealt with.

Common causes of E4

A short circuit reported by the IGBT sensor
A power stage on the mainboard that has failed
A mainboard that needs replacement

✓ One safe check you can try

1. Switch the cooktop off and disconnect it at the breaker. 2. Do not restart it repeatedly to test the code. 3. Note the model number and E4 for the call. 4. Call us so we can arrange the mainboard work.

! Why to stop there

E4 points at the power electronics, where high voltage is present.
The fix is a mainboard replacement, which a technician must do and test.
We give a written price before we order or install anything, and the repair has 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.

E4E4 questions

What is the IGBT?

It is the power switching device that creates the high-frequency current for the induction coil. If its sensor reports a short, the cooktop shuts down instead of risking more damage.

Will a power reset fix E4?

It is unlikely. The official remedy is replacing the mainboard, so a reset is only worth one try to see whether the code was a one-time event.

Is the cooktop worth repairing?

That depends on the model and age. We quote the mainboard replacement in writing first, so you can compare it with the value of your cooktop before agreeing.
