Diva DDP-50 induction cooktop the 2 left burners stopt working. How can I fix this.

We aren't Electrolux, we are FixYa dot com, and you appear to have fixed it.

Resetting the board would simply involve cutting the power to it. Induction cooktops are a relatively new innovation to the home markets are in general, all Induction cooktops fail due to failing electrical components. I have a 50 year career in catering, and 10 years with induction units. Even the catering quality units with a single hob that cost $1,800 fail in 18 months to 2 years.

Contact Electrolux direct and ask if they can find the failed component and repair the board.

Hi Ross,
The error code E A on your Smeg induction cooktop indicates a communication error between the electronics of the cooktop and the specific burner. This could be caused by a fault in the electronics of the burner, a wiring issue, or a problem with the main control board of the cooktop.
You can try to reset the cooktop by turning off the power supply to it and then turning it back on after a few minutes. If the error code persists, it is recommended to contact Smeg customer service or a certified technician for assistance in diagnosing and repairing the issue.

Induction cook tops do not heat by convection... only the cook ware gets hot. Your cook ware has to be made or encapsulate ferrous materials. More simply put; if a magnet won't stick to the pot it won't work on an induction cook top.

Same problem - any solution yet?

I have the same problem, and resetting the breaker didn't work. There is no child lock on my unit that I can find. Was your issue ever fixed? Does anyone have any other suggestions?

Just change big fuses in box.

Throw your circuit breaker that leads to this unit for a few seconds, then reset the breaker This unit is very sensitive to power fluctuations.
