Krups Error Code 09 ((hot)) «Editor's Choice»

Calcium buildup (limescale) in the internal water circuit can change the pressure dynamics. When the pressure is wrong, the piston cannot move against the resistance, triggering Error 09.

Making back-to-back lattes subjects the thermoblock to sustained, high-temperature strain. Allow the machine a minute or two to idle and stabilize between intensive frothing sessions.

Finally, the issue could be in the wiring that connects the NTC sensor to the main electronic board, or even on the board itself. Wires can become frayed, or connectors can oxidize, creating a poor electrical connection.

If the error is intermittent and allows you to access the menu, immediately run a descaling cycle using Krups descaling powder.

When the machine says it is time to descale, do it immediately. Delaying the process allows scale to bake onto the thermoblock, accelerating sensor failure. When to Contact Professional Service Calcium buildup (limescale) in the internal water circuit
