What SELF-DIAGNOSIS
actually means.
The EC24 runs a self-check when it powers up. Wolf says this message stays when a component will not pass that check. A power reset clears one-off cases; if it comes back, the component needs to be found and replaced.

What to do when SELF-DIAGNOSIS shows on the coffee machineKind of codeControl board and power
The electronics that read the keys and run the grinder, the pump and the heater have flagged a problem with themselves or with the power reaching them: a supply that dipped or spiked, a board that lost its settings after an outage, a display or touch panel that stopped answering, or a relay that stuck. One switch-off at the key or the breaker clears a passing glitch; a message that returns, or any hot smell, means the power stays off and a technician tests the board.

Shows up asWhat a Coffee Machine Error Code or Warning Symbol Means
A coffee machine error code may show as a short string of letters and numbers, a flashing symbol for water, grounds or the brew unit, a short sentence on a text display, or a machine that stops with one light blinking.

Before you book,
in this order.
Each step comes from Wolf's own guidance for SELF-DIAGNOSIS on its coffee machines. Follow it to the end: the last card says whether this is a visit.
Switch the breaker for the coffee system off for 30 seconds, then back on.
Start the unit and watch whether it moves on to normal operation.
If it works normally afterward, no further action is needed.
If SELF-DIAGNOSIS returns, book a visit and mention how long it stayed on screen.
Still there?
It usually turns into coffee machine control board repair. Book with the code and the model number.
What not to do
A brief SELF-DIAGNOSIS right after the master switch goes on is routine. Coffee residue inside the unit is reported differently, as GENERAL ALARM.

In Wolf's own words
EC24 is not able to complete self-diagnostic because of component error.

Still showing SELF-DIAGNOSIS?
Three things make the booking useful: the message or number exactly as the display showed it, the full model number from the plate, and whether the machine still grinds and pours at all. Send those and the likely part can be looked up before the van leaves.
