Question about Krups Coffee Makers & Espresso Machines
The heat sensor on the boiler is not detecting any temperature change. It could be a wire or terminal off. The sensor is right at the front of the boiler. If the sensor is faulty it means a new boiler because it's stuck on in the factory.

After I changed piston sealing I get the same error 09. It was caused by missing connection to the thermoblock temperature sensor. In my case both connectors for thermocouple were cracked. They are located directly on the body of thermoblock, below two fuses, covered by rubber housing. After I solder them again on the position error 09 disappeared. Unfortunately it is necessary to open at least front panel of the machine. Moreover I tink that there is also important to save polarity of those two cables.
