Loose or corroded connectors between the sensor and the main logic board.
Unplug the machine from the power outlet for at least 10 minutes. This allows the internal capacitors to discharge and the sensors to reset. Sometimes, a simple software glitch triggers the code, and a cold reboot clears it. 2. Inspect for Scale
If your machine is still under warranty, contact Krups support before attempting any internal repairs. If out of warranty, Error 09 is usually a "repairable" fault that requires a relatively inexpensive replacement part rather than a whole new machine.
If you haven't descaled your machine recently, mineral buildup may be the cause. While the machine is off, check the water tank and intake. If the machine allows you to enter the maintenance menu despite the error, run a descaling cycle immediately using a Krups-approved citric acid solution. 3. Check Environmental Temperature
A technician will use a multimeter to check the ohms on the NTC sensor. A reading of zero or infinity confirms the sensor is dead.
Before calling a technician, you can attempt several DIY fixes to clear the error. 1. The Hard Reset
The most common culprit is a damaged or short-circuited temperature sensor.
