Every Wolf coffee system has a removable infuser behind the service door that compresses and brews each dose. After cleaning it has to slide onto its support and pin and click in, with the two red buttons popping back out. If the machine does not sense it, it will not brew. The infuser locks in place if the unit was shut down with the master switch instead of the front button. Wolf coffee machine display What to do when INSERT INFUSER 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.

Switch the coffee system off with the front On/Off or standby button, never the master switch, and let it cool. If it comes back, it needs a visit. ### Why is the infuser stuck in my Wolf coffee system? It stays locked when the unit is switched off at the master switch, which skips the shutdown that releases it. Turn it on, then off with the front button, and try again. ### Should I wash the Wolf infuser with dish soap? No. Wolf wants a five-minute soak in water alone, then a rinse and towel dry, since detergent and vinegar both harm the lubricated parts. ### How often should the Wolf infuser come out for cleaning? At least once a month. Always do it with the machine switched off and cooled. --- **[Read on the site: Wolf INSERT INFUSER: the coffee system does not sense its brew unit](https://coffeemachinerepair.center/error-codes/wolf-insert-infuser/)** **[Book a visit with CoffeeMachineRepair.center](https://coffeemachinerepair.center/schedule/)**
