Hi Dolores, I understand that your cooktop will not turn on after receiving an error code "40". Usually this error code can indicate a communication error between the Induction Module, Relay Board, and Control Board. I would also recommend doing a hard reset by unplugging or turning the household power breaker off to the appliance for five to ten minutes. If the problem persists, please reach out to a professional technician. Hope this helps! -JK

Good Afternoon friend, I appreciate your inquiry!

Typically on an Electrolux induction cooktop the "E4" error code stands for key sensor for timer. Which means you could be experiencing an issue with the right board, center board, or left board. I would perform a reset on your cooktop and you can do that by flipping the household circuit breaker off for ten minutes.

If that does not assist with clearing any false error codes or the error "E4" continues to display I would suggest seeking assistance from a professional for proper diagnosis and repair. Hopefully this helps. -Matt

You really can't. Ceramic can be repaired but it can be short term. There may be a sealer they can put in the opening.

Verify AC input voltage at the cooktop input. Verify AC main input cables, screws and jumpers. Verify the fuse resistance to be approximately 0 ohms on the Induction Module. Replace the Filter Board on the Induction Module.

This part should still be available from a local parts outlet. You'll need model and serial and color. Model and serial are located underneath the unit on its bottom.
You won't like the price. Good Luck
