What ERRx
actually means.
Smeg's combi microwave ovens such as the SFU4104MCS print error messages as ERR plus a number. The manual does not explain each number to owners; it asks you to note the message, the function and the temperature that was set.

What to do when ERRx shows on the microwaveKind of codeControl board and touchpad
The electronics that read the keys and run the cycle have flagged a problem with themselves: a key that the control sees as held down for too long, a membrane keypad worn through or swollen by steam, a lost link between the keypad and the board, or a board that failed its own check after a surge. A breaker reset now and then clears a glitch; a stuck key or a code that comes straight back points to the keypad or the board.

Tracing a dead display, keys that do not answer or a code that keeps returning to the keypad, the ribbon, the relays or the main board, and replacing only the part that failed.
Shows up asWhat a Microwave Error Code Is Telling You
A microwave error code may be a letter and a number on the display, a lock or demo word, a row of dashes, or a beep with a blinking clock, and it can show while the microwave still heats or block every key until it is cleared.

Before you book,
in this order.
Each step comes from Smeg's own guidance for ERRx on its microwaves. Follow it to the end: the last card says whether this is a visit.
Write down the full ERR message and what function and temperature were set.
Check that demo mode and the controls lock are off, since those cause no-heat and dead-key complaints on their own.
Turn the circuit off and on again once the oven is cool.
If the ERR message returns, book a visit and give the details you noted.

What not to do
An ERR message is different from the demo and controls lock settings, which Smeg lists separately as causes of a cold oven and dead controls. It is also not something a menu setting will clear if it keeps coming back.

Three details make the booking useful: the characters or beeps just as they appeared, every character of the model number, and whether a cup of water still warms up. With those, the technician arrives already halfway to the answer.
