What INSERT BREWING UNIT
actually means.
The infuser is Smeg's name for the removable brew unit behind the service door. It comes out for monthly rinsing and has to be clicked back in before the machine will brew.

What to do when INSERT BREWING UNIT shows on the coffee machineKind of codeBrew unit
The brew unit did not reach the position the control expected, or could not press and brew as it should: it is caked with old grounds, dry where it needs its grease, jammed by a dose too large, or its drive and seals are worn. On a machine with a removable unit, lifting it out with the power off and rinsing it is the owner's check; a fixed unit is cleaned by its own cycle, and anything past that is a visit.
Usually leads toCoffee machine brew unit repair
Resealing, lubricating or replacing the brew unit that tamps the grounds and presses water through them, removable or fixed.
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 Smeg's own guidance for INSERT BREWING UNIT on its coffee machines. Follow it to the end: the last card says whether this is a visit.
Turn the machine off using its own on/off button and wait for it to cool.
Open the service door, slide the infuser onto its guide and push until the two colored release buttons spring back out.
If it will not go home with light pressure, leave it and book a visit rather than forcing it.

What not to do
The line does not mean the infuser is dirty. If it will not come out in the first place, the machine was not turned off correctly, which is a separate case in Smeg's table.

Still showing INSERT BREWING UNIT?
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.
