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. Smeg coffee machine display What to do when INSERT BREWING UNIT shows on the coffee machine ### Kind of code Brew 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 to Coffee 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 as What 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. ### Make Smeg A Smeg espresso machine is repaired at the owner's kitchen counter after a single test shot shows where the trouble begins. ### Source Smeg automatic built-in coffee machine instruction manual (linked from the US CMSU4303X, CMSU4104S and CMSU2104G pages) Smeg US built-in automatic coffee machines CMSU4303X (Classic, listed as retiring), CMSU4104S and CMSU2104G (Linea).

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. ### Still there?

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. --- **[Read on the site: Smeg INSERT BREWING UNIT: the infuser is out of the built-in](https://coffeemachinerepair.center/error-codes/smeg-insert-brewing-unit/)** **[Book a visit with CoffeeMachineRepair.center](https://coffeemachinerepair.center/schedule/)**
