What to do when INSERT BREWING UNIT shows on the coffee machine

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.

01

Turn the machine off using its own on/off button and wait for it to cool.

02

Open the service door, slide the infuser onto its guide and push until the two colored release buttons spring back out.

03

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.

Questions
about INSERT BREWING UNIT.

Can I clear INSERT BREWING UNIT myself?
Turn the machine off using its own on/off button and wait for it to cool. If it comes back, it needs a visit.
How often do I clean the infuser in a Smeg built-in coffee machine?
At least once a month. Rinse it in water only, without soap.
Why is the Smeg infuser hard to take out?
The machine was probably switched off at the main switch instead of with its button, so the infuser did not park. Turn it on, then off with the button, and try again.
Can I run my Smeg built-in with the infuser out?
No. The display blocks drinks until the infuser is back and latched.

Back to your everyday

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.
