Krups EA8908 - message "Disconnect and reconnect or use application"

✨ The Krups EA8908 espresso machine displays the error message "Disconnect and reconnect or use the app," often accompanied by relay clicking sounds and followed by "Automatic maintenance" and prompts to place a 600 ml vessel under the nozzles. This issue is commonly linked to faults in the heating system, temperature sensor (NTC sensor), flow meter, or water filter. Several users reported that broken or detached cables from the temperature sensor or a damaged sensor tip attached to the boiler cause the error. Repair solutions include soldering or gluing the temperature sensor tip back onto the boiler, replacing thermal fuses (G4A00 216 ºC), cleaning or replacing the flow meter and its filter, and descaling the water system using liquid descalers. Some users noted that clogged water filters located near the flow meter inside the machine can cause water flow reading errors. The problem may also arise from coffee grounds blocking the brewing unit or plunger. In some cases, resetting the machine by unplugging it for several days or removing and rinsing the water tank temporarily resolves the issue. Replacement parts such as the NTC sensor element and Littelfuse 124JG1K thermistor are available on platforms like Allegro. The error can also be related to blown thermal fuses near the NTC sensor, which may cause additional messages about tank alignment due to shared wiring. Overall, the fault is often hardware-related, involving temperature sensing and water flow components, requiring inspection, cleaning, or part replacement to restore normal operation.
